I’m an mechanical/mechatronic/ robotics engineering student and I like to spend my spare time to develop and build various mechatronic objects/prototypes, with main focus on manufacturing machines (e.g. CNC milling machines, lathes; 3d printer; robotics..)
Come on, please give us at least one video on the electronics and design process. This is so incredibly cool and I so badly want to learn about it for my own Uni project. This video is a massive tease as a mechanical engineering student who's super itnerested in robotics but hasnt a clue where to start.
Hello! I have seen many different projects, but I have never seen such results! This is great! May I ask a few questions? 1) what software are you using? Motion planner? Isn't this a ROS package moveit? 2) are you considering the option of free distribution of the project or perhaps selling it? For example, we would like to make the same robots and teach students how to work with mechanics and software.
I would 100% join a patreon for educational content on how to build this, Im hugely interested in robotics and want to do a robotic arm for my final year uni project.
30% max speed looks cracked honestly. It might benefit from a little bit higher payload with like 2x the reduction. (I'm sure that's way easier said than done haha)
I don't get it... Why can't the hyperloop just use this design, it would mean that the tracks can be literally iron bars suspended by some supports. And why not lose the tunnel, and just make the tic tac pod a very long train like body. I mean wouldn't that be maglev, but a LOT cheaper?
Are J5 and J6 fully printed? Also, I just bought a Annin Robotics AR4 Mk2. Printing the parts for it right now. But that is based around open loop steppers. A very simple robot arm. (My respect to Chris Annin though. This was the most capable arm I could find at the price point and he's a hero for making it.) However, your arm makes me drool just thinking of the capabilities! Compliance is a game-changer for advanced robotics. Ugh~~~~
Also, since the main mode of failure for prints is tension, maybe putting some using a long bolt or some tensioned wires could help keep it in compression? Kinda like using reinforced concrete. I'm sure this is wildly impractical and not even necessary. But a cool thought :P More relating to the science printing than to your project specifically.
Joint 5 has two machined aluminium parts with petg covers. Joint 6 is printed from aluminium and machined afterwards. Actually no structural part is printed.. I didn’t had the chance to check the AR4 in any detail yet, but he for sure put a lot of work in the his project! Yes, compliance was a key factor for me. It really extends it capabilities.. Fun fact: in the hand knob (Joint 6) for grabbing it, I did exactly this: Using 4 screws for compression. I don’t thrust this layer bond in a critical part :D
@@TheRealMrLaserCutter he might have gone with one of the machining networks like jlcpcb, or xometry. I don't know if you necessarily call this for the common man because it's probably pretty dang expensive. But using these services definitely cheaper than buying your own printer and furnace for curing. But then again, his whole robot is fully machined and beautiful, and not necessarily intended for someone who can't afford those fabrication techniques right now. If you're looking for a really good robot add a great price, I would consider the Annin robotics ar4 mk3. It's really affordable. Around like two grand. And it comes with basically all the structural pieces made of aluminum. All joints are preloaded with tension to take away any play. High quality bearings all around. I would say it is an excellent design.
How is this a "spare time" project man? O.O You are literally a god amongst men. Most people could not dream of achieving this if they dedicated their life to it...
