Now if you add a metal detector and gps based mapping software that records each detection for you to go back and find the metal later-Then you have something! Something I invented years ago, you made it possible and automatic once this is perfected. Think of it: you could have this autonomously find metal in large areas, taking most of the leg work out of the equation. Excellent videos, I watch them all.
@@MarcAntoine01 Another genius idea, also sellable, but for a life saving purpose. That is a multimillion dollar idea many large countries would use.. but surely it already has been tried
For marking, a solenoid controlled spray can, or small flags, fired into the ground, might prove simpler to manage as you don't have to use mapping. Pair that with a a random search pattern, and you'll have detection from multiple directions, to make detection more reliable. Leave in a field for a week, and check the markings armed with your pinpointer only. Could use different colors for ferrous and nonferrous?
I have done metaldetecting for years, and i can say this wont work like you said. You need to move detector side to side like once per second. That needs a motor system and causes wobble. Then, metal frame and wires will cause interfearance with the detector. Also, you really need to hear the signals from the detector by yourself so you can skip like nails and stuff like that. That come only with human experience. Cool idea tho
One small suggestion for future missions: doing a loop course will stress the motors on one side a lot more, if you turned your waypoint mission into more of a figure 8 it would even out the work both sides are doing a bit. I love the idea of this bot just trundling around in a field all day, hope your Barbie gearboxes make things work!
I made a "battlebot" type robot with those kind of motors and won second place against much more sophisticated and expensive competitors. In the end, my choice of surplus, used batteries (batteries were not very affordable back then) is what failed and not the motor packs. I think the only reason that they were not commonly used back then was that they had non-standard drive outputs and 3D printers were not a thing. I ended up taking a welding class, specifically to make adapters for them.
Man, I usually never comment on RU-vid, but I have to say I really look forward to each one of your videos. I really enjoy the content and all your effort! Keep it up!
What he should do is create and autonomous boat to launch and autonomous plane that drops an autonomous rover that launches and autonomous rocket into space.
Its hard to find custom tracks, 3d printers are really the easiest thing to make them, and I can be fiddly dealing with sprockets, harder then wheels, but yes your right, it needs them
If you separate the wheels and glue the tires to the rims with silicone you can drop the air pressure to almost 0, way better traction and a little bit of suspension
I want to make one like this with a mower attachment. I was thinking of adding steering to each wheel. If you could angle them in combination with the motor drive differential and avoid skid steering, it should improve traction.
@@tigeroll that design works fine for flat surfaces with predictable traction, but if one wheel falls in a hole or spins, there is no backup traction to get you out. My zero turn mower is made this way and it gets stuck on hills and wet grass easily. If a wheel starts slipping going down a hill, there is no way to steer it.
Hoverboard wheels with in-wheel motors are also very usable and reduce complexity. We're using them with two dummy wheels on the front and 2 wheel drive for our rover. Also, weight wise it might be good to use flexible solar panels.
...so I designed an additional 3D printed cycloidal gearbox with a 13:1 reduction ratio that goes in series with the Barbie Jeep gearbox........ ooooofffff course ya did!! LOL. I'd expect you to 3D print a cold fusion reactor next to power the thing. Great job on this.
Maybe ad some little feet actuators? Then if the program detects the GPS stays stuck in one spot too long, it could cycle those every now and then to lift the whole vehicle up and set it down again to try and get it un-stuck. Might help with the treads digging through the ground. Other than that, perhaps two sets of bogies and some free-spinning wheels that aren't driven to spread out the weight more? It'd end up looking more like some kind of rover yet. Also I don't see any problems with the new gearing. Just that the plastic it's made from could shear if it's loaded up enough. (Depends on what kind of traction those wheels could get.)
This is awesome! Consider using wheels with grousers like the Mars rovers. Should work well on soft terrain. For a smaller rover this size I would increase the grouser size in comparison to Curiosity to like 2cm with a 10cm wheel diameter. A simple wheel like that should be 3D-printable as well!
If you buy an old powered wheelchair and take off the seat you have a 'bogie' ready for about 15km of heavy work. Add the electronics...Im' in Ireland and already have one if you'd like to Co operate. I have lathe, milling machine fold and shear etc, so I can look after mechanical part.Joss in Cork, Ireland.
You should use the Mars rover suspension. And then the back sets of 2 tires on each side would be connected by chain so 1 less motor and then expand the solar panels another foot on each side with a down angle 38 degrees the rover would have the rover suspension in the back and don’t change the front. If you don’t/won’t have a sensor you should put bumpers. 👍 Thanks for reading.
You can flash the firmware on the multi rotor esc to support bidirectional motors. Nearly all esc's can do it. Even tiny whoop drones can be flashed for 3d inverted flight.
If those wheels on that rover are solid and not air filled, I would cut a paddle or lug style tread into them, so they provide great Driving grip in soft areas.
Give it articulating steering then it will be unstoppable and you could even add a get unstuck option where it can drive and steer back and forth to “walk” out of a hole
Hi I am just a kid and I just want to say I’m fascinated with the stuff you do my life I always want to stuff like you do and you’re inspiring me I just love it and I love your videos keep up the good work your the best!!!! 😃🤟
You could prototype structural stuff a lot faster/easier with 8020 aluminum profiles probably, certainly less welding involved ;-) Love the concept though, definitely following.
my homemade rc boat uses a old plane brushless esc, to get it to reverse i just used a old tamiya MSC, and a servo to reverse 2 of the wires, so at the swick of a flitch it can reverse.
If you have enough solar power a 4G uplink and a website showing it's current position (obfuscated!) and it's current total distance traveled etc. would be awesome. So we (subscribers) could follow this little rover on it's purely entertaining mission :D Add some BMP280 sensor (temperature, humidity, pressure) and it could be the first autonomous, motorized weather station.
Maybe use swivel casters for your front wheels, like power chair has... or entire power chair base, including motors / gearboxes (one I tested though has major disadvantage - too low, maybe 1" clearance above the ground).
Not sure if you are responding to posts, because I have a question about the 'autonomous solar rover'. ? Why did you choose the type of skid-steering versus other types of steering? I'm guessing it made it easier to follow the GPS way-points. I'm slowly working towards a GPS, FPV drone aircraft. I have some experience with rc planes and one helicopter. I have been accumulating some Arduino and Rasberri Pi boards, and associated parts. Also, I purchased a 3d printer in February, 2021. I have a ton to learn. I have some cnc, Bridgeport, and lathe experience. And a tiny bit of welding experience. I love the autonomous Tupperware boat. I saw a post regarding a company that offers drone support, especially when making delieveries. My 1st. thought was your videos and which direction you went in after graduating from college. 'Technology Demonstrator'. My ultimate goal is aircraft, but it would make sense to learn on the ground versus losing an rc plane, and more importantly, the electronics. Thanks for the videos, they have helped give me some direction, advice, and motivation.
I can’t believe I’ve never seen this channel before. It’s almost embarrassing. Well I subscribed and hit the bell and thumbs up. Looking forward to seeing this beautiful creation when you revamp it.
OMG dude I have this same idea too, building roving robots, I always feared they'd get stolen but on your own property it's not bad. 3:14 Holy shit you can ride it? hahaha 4:46 damn look at the aspect ratio on that thing What is my purpose? You drive back and forward in a field until you die. Just throwing this idea out there for you: drone submarine, surfaces at night for communication. The sat modules are mad expensive but gsm works too I guess not as "cool". Not sure if you can charge panels slightly underwater, probably not. Future project for me but not sure when I'll get to do it.
Fro the GPS problem: put a metal thing under the GPS, and make sure that there is no metal blocking the visibility to the satellites(it can be on the horizon!).
@@rctestflight do you think you could upload a video showing what gps and software you use, and how to set up the gps waypoint missions? Thanks in Advance
That's really cool! Maybe add more of those grips on the wheels, maybe 4 per wheel, and it will be pretty good I think. For the GPS mount wonder if having a little antenna tower would work too, though I guess it would cast a shadow on the solar panels.
Very cool project and I feel a little embarrassed at my attempt to help you with tuning issues on the Ardupilot discussion boards. I thought you were a Newbie, but you are WAY beyond me, I think! :)
