I was wondering how many English speaking people in the world today are adept enough to comprehend his treasure trove of material. That’s not a slight on English speaking folks. I just assume folks speaking other languages would be quickly lost without hearing his knack for teaching as he guides us through his journey. Jeremy’s in my top 5 for sure!
@@JohnDuthie just saying compared to others doing this on youtube sci/tech he has a big following. without saying sci/tech needs more exposure as well as he. but just not sure how big it is of interest to the average youtube watcher if it doesnt explode. there are some really talented youtubers that dont get near the following as the ones going by the seat of their pants. im a new sub here, i like what he is doing and offered to help with the equipment i have if i can.
Sharing your failures as readily as your successes is a much appreciated and powerful teaching tool. Beyond affirming that these things simply do happen and are a normal part of the learning process, you demonstrated how to take a moment to reckon with the issue and move beyond the frustration. Dig your videos, Jeremy, the subject matter and your excellent example as you learn.
also, analyzing the *decision making* that went into causing the mistake, means he learns from it, and we learn from it. sometimes its hard to admit being dumb, but the upside it to learn why you where dumb, and how to do it differently next time. Better labeling, or better yet, key the plug so they cannot be swapped accidentally. Sometimes this is as easy as removing/adding pins, sometimes, it requires selecting mechanically incompatible connectors (like he hinted at).
Humans learn from mistakes. We can either learn the hard way from our own mistakes, or the easier way from other's mistakes. While it is good to strive to not serve as a lesson to others, it is noble to step up and share one's errors to help others avoid them.
I'm a mechanical engineer that has spent the past 35 years designing and building factory automation for a living. For a large part of my career I have been self employed and during this time I have tended to structure my workload such that I am the only guy on the project. This means that I am designer, fabricator, machinist, electrician, and commissioning engineer. Let me start by saying, "I feel your pain". Its so easy for people watching to jump in with 20/20 hindsight and state the obvious. In reality, I know first hand how difficult it is to cover every angle of a design to minimize start up and commissioning issues. Secondly, I want to commend you on the way that you involve your family into what you do on your channel. Exposing them to the wonders of technology in the way (and to the degree) that you do is extremely inspirational and refreshing. The world needs more engineers like yourself. Keep up the GREAT work.
Mad props for having the guts to show your audience when you made a costly mistake. Teachers with this kind of authenticity and humility reach students on a far deeper level than those who sweep gaffs under the rug. Not to mention keeping the language kid safe and ending with a smile! Hats off to you, sir!
That hurts..... It still crazy to think. A couple years ago you were tinkering in a shoebox shop finding awesome space saving solutions for portable tools etc. And now your welding, machining, and building robots!! Congrats bud!! Your content is awesome as always. Keep it up
My favorite will always be the washing machine break-down. I now have a giant square shaped planter out of an old washing machine, lovingly rescued from the side of the road. (gardener here)
All your videos are truly outstanding. The "If I can do it, you can do it, and I'll show you how." aspect is both 'giving' and inspirational. I would not be surprised if you find out you changed some people's paths in life. You are a natural born teacher and source of inspiration.
There are plenty of robotics engineers that don’t think about these kind of things when designing or programming robots. This is a great series, and you can go on forever with improvements!
@@Jeremy_Fielding Soooooooooooooooo very frustrating when it happens, my friend, and so easily done. The number of times I've saved a file under the wrong name (prior to when OS's warned you you were about to overwrite something) or have done exactly what you just did plugging the wrong plug in and letting the smoke out... It's not so bad if (like my plasma speaker) things just blow up for seemingly no reason at all, but so much worse when a moment's inattention which usually results in us questioning ourselves if we should triple check before power up.... "nah! I already checked twice" we tell ourselves. We humans are lucky our legs don't twist in certain directions. we can't actually kick our own asses with any great force. ;) Still a banger video though!
@@jimmyb1451 Learn from aviation: Good pilots adhere to a variety of written procedures that they learn by heart but anyway read. The exception happens only when something much out of the ordinary seems inexplicable and demands team work to decide what to do, given the circumstances. So there are procedures for this, for that, and for that other... a long list of drills. Some are performed in sequential order (and their completion is announced out loud for all the team to hear): normal operation procedures. Some other are called for in specific but abnormal circumstances (I remember, for example, Operation in cold weather) or in emergency situations. So: prepare and write your drills, each with a name (what phase you are, or what main thing is done in the procedure) and a list of points to first perform, then re-read and check that the settings are as the list demands, even if such a list is very short (and it should include whatever security and safety issues could occur during that phase, i.e., checking out fire extinguisher is nearby and full, gloves, masks, apron, and boots are worn, no unneeded flammable material nearby, etc., in the Before Welding checklist). When the next procedure requires such prior checks and actions to have been done, you know you've done because you just declared that procedure completed. So, you start this next procedure and go on safely. After-this or -that procedures may also be useful (generally brief drills). Drills may also contain some piece of advice on what to do or avoid if certain things are this or that way. This procedural method saves lives and wealth, and sometimes it even saves overall time spent!
@@wafikiri_ What you're describing reminds me of "pointing and calling" a safety protocol used by Japanese railway workers and others where you point and say/call each step of procedure. en.wikipedia.org/wiki/Pointing_and_calling
What a punch to the gut. Catastrophic failure, unrecoverable, it was preventable, and it's completely your own fault and you knew it almost right away. Hardly anything even to learn from it because you knew in advance how important it was not to get those cables mixed up. It just happened anyways. Man, what a frustrating day that must have been for you. That's the kind of event for me that can have me put the project on a shelf for a year or two. Glad you persevered and didn't let the mistake take over.
Bad things happen. A man in California rebuilt a truck from the ground up. Took him three years. Drove it 2 miles to a local store. A truck crashed into the car. No way to repair. The man just said, at least no one got hurt.
I love that you show your mistakes, sometimes after watching so many of these videos I begin to think I'm the only one who makes mistakes. Thanks for keeping it real.
I have exactly zero experience in welding or machining, but I imagine the stress and flexion of the part when welding can warp your precision milled cuts and then no worky.
specifically due to the thermal expansion of the metal you are welding. The molten metal, in it's molten state, is notably less dense than the cold metal on the other side of the part, and as it cools it contracts until it reaches the same density. Because the metal hardens before it is entirely cooled, it still has contraction to do after it becomes hard, and thus it creates a good deal of tension on that side of the part which tends to bend the whole part in that direction. Thus, welding perfect right angles into parts too large to clamp to a table is a very challenging task indeed.
Its the same reason S and O and I arent used in auto VIN numbers.. Tooneasily confused so we just dont use em. But in the home shop... These things are bound to happen as one point or another. It's all about how you handle it. And Jeremy takes defeat like a champ. I can really appreciate that.
@@kjfuson92 the letter S is used in some VINs (European IIRC) but your point is solid. I wished manufacturers would avoid using similar letters in part numbers, although I get that there are technical reasons why that probably isn't possible. In practice, a label maker and a clean font will help in the future.
That was so FREAKING COOL!! Usually, talented engineers just want to show off the finished product. Jeremy makes his videos a lesson for up-and-coming engineers by talking about design issues, resolutions, executing on the design, more. Makes me want to build my own Jarvis.
@@charlieroney1008 Fair point, but given all the hand-made steps, would you want to support people in a project like this? Lot of liability, and lots of room for error that our guy doesn't have control over. I wouldn't want to support such a complex project.
@@The-KP yeah but I am on my quest to actually acomplish all of this like I actually want to do one of these giant robot arm builds but theres no info on what drives the ones maybe bigger than jarvis as for liability he has none if I deicide to be a dumbass with stuff i decide to make myself its not like you cant go build an AR4 robot arm that can do most of the same things I just want to move like 10+pounds with my arm. in a larger size
This world was made better by men like you, the perseverance to overcome adversity is what made America. You have an amazing impact on so many and stir the minds of all who see your videos. Keep up the great work Jeremy.
considering the motors are new and not pulled from old equipment i'm sure the encoders could be purchased and replaced for a pretty minimal cost. Automation direct has their name on them but I think they are sourced from either Delta or Yaskawa. Parts should be cheap and plentiful.
Yeah, I was thinking that too. If its just the encoder thats blown, that might be a replaceable part. Tho I'd probably do the same as he did and just order new and then look to repair when in a better frame of mind.
@@frenchonion4595 I've had good luck with Leadshine brand products. There is a US distributor called AMT that sells their servo/stepper products. If you're looking for single/3 phase induction motors, its hard to beat the selection of automation direct.
There are other advantages to the belt that you didn't mention. By adding the elasticity you reduce the bandwidth of the mechanical system (as you mentioned by the 'overshoot and snapping back'). This is likely outweighed by the otherwise greater rotational inertia (assuming you did your math right). The reduction in bandwidth though, also has an advantage, namely increased safety. By using an elastic element in series with your motor, you decouple the motors rotational inertia (which, because it is coupled through the gearbox, is very large) from the arm. I.e. the inertia from the arm with the motor directly coupled to it is higher than if it would be coupled through an elastic element. This effectively spreads out the force of an impact over a larger time period making it safer to work with. Also, it gives the controller more time to deal with the impact and reduce impact forces/energy even more. That is the second point. Although the added belt elasticity decreases POSITION bandwidth of the system, it makes force control much easier. By measuring the belt deflection (difference between the input and output pulleys) you can deduce the torque/force applied as the deflection of the elastic belt is roughly linear with this force/torque. This makes it possible to relatively cheaply implement force/torque control on your robot. If you do interactions with humans, this is a superior way of doing control (namely force control + outer loop of impedance control). Because if a robot is commanded to a certain position in position control, it will move with all its might to get to that point, potentially breaking things (including limbs) in the process to get there. With impedance control there is inherently a limited amount of energy that will be used, and if an object is encountered it more naturally interacts with it. You can implement position control through impedance control by using a virtual spring between the position of the robot arm, and the point where you want to go.
fascinating project and thank you for including the errors as well as explaining. As to your question, metal can warp when welding and mess with the precision milling you've done. But you seem to be pretty good at mitigating that. Thank you for sharing.
You, my friend are a genius. You make everything easy to understand and you put proper effort into your projects and videos. Really appreciate these videos. Keep up the great work!
I love your passion. You are a true teacher and the humility you seem to express in your life is humbling to watch. Also, what a good looking engaged family. Thanks for the pick me up.
If you havent done it atleast once you probably only just started. Theres a reason I prototype my projects on knockoff arduino boards and save the real ones for the final iteration :)
I think I have a box of IC's that have suffered my late night "oh hey, lets just get one more thing wired up, I can do this!!"... zzpfffft.... shit, well I guess I have the make a wish the genie is out...
I love your stuff and I am so glad you are doing stuff like this! It has helped me in so many of my own projects simply by understanding the concepts I need to know! And when you combine all of your knowledge while still educating people is amazing! It's entertaining and helpful to see things in actual applications! Really helps when applying them in other projects!
Also I think the order of operation matters simply due to warping caused by the rapid heating and cooling when you weld. This could distort the part and the accuracy of it after machining.
Your channel should be huge by now. You are a great educator. As one father to another, I couldn't help but think "awesome" when I saw how you were teaching your kids and playing with them.
Don't think that'd work. The fuse blows on current, not voltage. And thanks to mr Ohm's law, a lot of damage could be done by 24V before a fuse that is suitable protection for 5v blows. I could be wrong tho. You could build over voltage protection into the circuit, but easier to just label things better.
I love how you can still show us your contagious & beautiful smile, even on your bad days. Thanks for showing us how to adapt and overcome, keep up the great work
Oh man…I’ve been there before a number of times. That moment of dread when you do something stupid that fubars your project or what you are working on. So disheartening….but hey at least you can always pick up the pieces. In my line of work when I fubar something people can die….so it really, really sucks.
I love the variation in camera angles, really makes the presentation more engaging. That’s in addition to the amazing project as well, thanks for sharing!!!
Why don’t you want to weld after machining? I would imagine it’s because the amount of heat introduced to the material while welding has a high potential of warping or deforming the material, even if only to a small degree. However, when working with precision parts, even minute changes in the material can create massive problems with fitting, alignment, etc., down the line.
I've heard this old Tony say that weld joints can pull things together - as the weld cools it contracts with an incredible amount of force, enough to pull things out to true if you don't plan your welds sufficiently I've never done anything precise enough to worry about these forces so idk the full extent, just quoting ToT
I think it's "weld distortion". Meaning, the warpage from heat that ruins machining level precision. Think what a can looks like if its been in a camp fire. There are some good videos about it on YT.
Probably not HAZ unless these are all on critical material strength locations. Most likely because you will always gets some warpage when welding, and this can easily throw off tolerances.
good ol' Automation Direct servo drives. almost cutting edge, almost reliable, but dang theyre cheap! We blew up a $3000 servo drive last week because a piece of copper wire fell into it.
I have been watching your videos for year and couldnt believe i wasnt suscribed to you already... As a welder machinist business owner for 25 years you never cease to amaze me with your abilities. I also love seeing the mistkes you make... that we all make. Keep up the good work and ill keep following
Hear me out- Jeremy Fielding + Stuff Made Here series. Project: Robots at Home- design and build a series of open source robots that can be built and used by average makers. Sell kits and/or plans. Show crazy use applications for these robots.
Now that's something I'd dedicate hours to watching if they ever posted something that long. But we should have a backup plan in case they cause the end of the world...
@@faielgila7375 I’ve thought about it more… Imagine this: This Old Tony, Colin Furze, Smarter Every Day, Stuff Made Here, Integza, Mark Roper, Jermey Fielding, Matt Parker, Make Anything, Styropyro, NileRed, Teaching Tech, Tom Stanton, Veritasium, and 3D Printing Nerd (or more, or less) network and take on a real world problem, and solve it through crowdfunding and engineering solutions. A pyramid scheme, but for ideas and solutions. They could reach out to their specific communities and crowdsource/delegate individual pieces of the overall project. The RU-vid creators would be the project managers for their part of the solution, using each of their communities as resources. In a matter of months, there could be thousands of makers, engineers, programmers, physicists, mathematicians, and chemists working in the same direction to solve a global human problem, instead of each of them doing siloed projects in no particular direction. Baseballs breaking the sound barrier and pool cues that can’t miss are cool (really cool) but not really pushing humanity forward. The beauty of this, is no single person needs to take on a huge amount of responsibility or dedicate huge amounts of time, other than a Google/RU-vid rep that keeps tabs on the project as a whole. A project like this would get global attention from everywhere, and create thousands and thousands of hours of RU-vid content. Sponsors would be all over it. Realistic ideas: *A realistic automated recycling solution- The world’s current solutions for recycling has completely failed. To fix the problem, there needs to be solutions from sorting at home, to industrial sorting, to supply chain. Plastic testing/sorting. Cleaning and processing into raw materials that are actually ready to be used in industry. *Home automation- affordable kits that can monitor use of electric, water, and natural gas/LP and manage each effectively. *Climate change- look at what can be done to improve carbon emissions by individuals. Tiny changes to each of our daily lives can have large impacts. I’m sure there are engineered solutions that can make our lives more convenient, and lessen our carbon footprint. *Affordable water purification- A lot has already been done in this area, but clearly there is still room for improvement. *Affordable and fast housing- 3d printed houses are happening, what else could this group of RU-vidrs come up with? *Home-based product manufacturing- home robots of various sizes that can perform various tasks. Some useful, some fun, some silly. Zero-point production isn’t just the future of energy, consumer products are heading that direction too. *Efficient food/plant production- automated vertical vegetable gardens, grains, mushrooms, root starches, latex (rubber trees/plants). If we all spent 100 hours spread across a couple years, we could solve these problems permanently. We just need some leadership to guide us and manage our efforts. @Jeremy Fielding Please go talk to your RU-vid buddies and RU-vid representatives to see if there’s any interest in this. Sorry for the novel.
Praise the RU-vid Algoritm for recomending me this video! How have I never seen channel before? Awesome work dude! + as a new dad it's awesome to see you have your children around you in the shop learning new stuff, very inspirational :) Cheers!
maybe to avoid any problems further down the line, why not 3d print some covers on your cables and plugs so that it is physically impossible to mix them up ?
I really like the fact you shared when you messed up with everyone. When you're self taught there is a lot to learn from making mistakes. Kudos on the great work. Love your videos.
Correct me if I'm wrong, but it's generally better to not weld after machining because the heat can cause the part to deform, yes? p.s. Love these videos! Keep up the great work :)
You can learn it too, man. That's the great thing about stuff like this. It takes effort, but if you have the drive, you can accomplish the same thing or even better. I honestly think that's why he's sponsored by that company from the video. Start from somewhere and build on that over time.
He's definitely got me beat too. Depending on how interested you are in the electro-mechanical fields, you might want to look into Arduino as a starting point. It's a lot of fun and a great way to learn about electronics, programming and combining the two.
Well that's why he makes these videos, so you can learn to do it to. Knowledge is power. If you've ever built something out of trash, you have the drive to build a manufacturing business. Most businesses are made out of trash, anyways!
Wow! The last time I watched, back when you started your channel, you explained a washing machine motor to me. Now you have 500k Subs and a robot arm! Im am impressed! Keep up the good work man! Cheers from Germany.
Man, working in production of industrial parts, I feel that moment of realization @12:50. Those are make or break moments. Great content Jeremy! You're a brilliant and accessible teacher
You seem like exactly the father I hope to be someday!! I want to show my kids all the amazing things I have learned about machining from my job and all the incredible things that are possible with creativity!!
You are someone to follow. I’m starting in robotics and I’m 50 steps behind you. Very inspiring to see your work, success and failures are both part of the process. Btw I know that setting up all those camera angels and managing footage takes a lot of work, much appreciated 👍🏻 keep it up
First time I have seen your videos. I love that you show both the failures and successes and how you overcame the problems as well to see that your human and make some of the same mistakes I might make if I had your knowledge and ability. Great work all the same. Just subscribed and sent this video to someone that you remind me of and whom I deeply respect.
When I was working at a mechatronic and setting up industrial machines and electrical cabinets, we had big multi-pin connectors with usually 60-100 pins. You had to crimp the pins onto your wires and then press them into the connector. The good thing was that you could put screws in some of the pin slots so that you could only plug in a specific connector and we usually only used certain pins for power. As most of our equipment used 24V, we rarely put other voltages on the connector, if only a few parts needed 5V or 12V we converted it after the main controller cabinet. When having hundreds of conductors between the main cabinet and some machine, not having to worry about messing up the voltage helped a lot. I remember once that someone from another team put 230V on some DC power line and fried nearly 30 motors and lots of sensors, was no fun to get fixed.
I’m over here trying to make a belt grinder and this dude has engineered a whole ass robot. Thank god I’m so humble, or this would really be a blow to me ego. Love your channel man just subscribed today and I’m all about it, wishing you continued growth and prosperity.
Even though it was a mistake it's one that many of your viewers wouldn't know to avoid. So great teaching lesson and I personally am glad it happened besides now we get to see another video on how you fix it.
When I watch your videos I can follow up your development procress very well. As I build and develop a lot of stuff at home I highly appreciate that you show your progess and failours. Showing your mistakes and how you deal with them afterwards helps me to understand your projects better and encourages me a lot learning more about your topics!
I'm impressed with your self-control and over-all attitude. It's actually more inspiring than the project itself - I'll never make an industrial robot. But I can aspire to deal with setbacks the way you do.
your videos are so inspirational. just watched this one before heading to my warehouse/shop where mi converting my cnc table to have a second gantry for a laser cutter on. nearly every part im making myself except electronics. so thanks. your videos energise me to go on
Its good u show the pain and anguish of building a large complex thing like this. Not everything always goes perfect. I know you will get it going in no time! Great vid.
I did a simple fan yesterday. I had forgotten how good it feels to do even the simplest project. You have been a big inspiration. I can't wait to get a bigger one started.
I love it! I can't wait to show this to my grand kids that people who build things like they see in movies, actually exist. Thank you Jeremy! You're truly an inspiration!
Treat success and failure with equal contempt :-) We’re with you - be strong! P.S. you can sometimes buy circular connectors with different “key ways”. That way they have the same pins, sockets and assembly process, but will not mate if the key ways don’t match. P.P.S. I’m working on renovating an old Sea King anti-submarine radar that uses: - Two-phase AC servos - Resolvers - Synchro controllers This is all old technology, but I’d love to see a video on these! Thank you for all your work educating the rest of us!
Love seeing how my knowledge has progressed over the years. I've watched engineering videos for most of my time on youtube and always "understood" what was going on, but not the actual engineering details that went into making it. Stuff like the safety factor and actually being able to do the concrete math in the design of such a machine has been something I finally truly understand. Having gotten more than halfway through my engineering degree these kinds of videos have slowly turned from "that's awesome I'd love to build something like that" to "this is awesome, I wonder how I would design one"... and I actually know how to design one now. I know for me this was a big hurdle to get over with my motivation and perceived capabilities since these videos made it seem like I'd never be able to build such a device. But give it time and lots of studying and you absolutely can.
I totally felt that. Sometimes you gotta breath before you can push through the next phase of work. Especially when its mentally intensive and you're frustrated with an aspect of the build process. Very impressive seeing you deal with that dread and loss and come back so clear headed and explain the issues with a great attitude. Stay motivated when you're able, remain driven always!
Man you have some serious engineering and electronics skills. I hope wherever you work outside youtube pays you well, or you have your own engineering firm.
I really admire your engineering but what you inspire me more is how you interact with your family into the passion you love. I hope if I'm ever blessed to be a father, that I may be like you.
You are incredible. Back when you were explaining 1 and 3 phase, and now all the way to a robot arm. I will send Patreon as soon as I am able. You are basically teaching a steam degree for children to adult. You cover everything, it's simple and clear, the physical, mathematics, physics, and the laws that enable everything. Any age can learn from basic to complex reasoning and practical skills. I have pointed many people to you, "the best place to really understand that is on Jeremy's Channel ". Truly a gem.
