Very, interesting project! I found it so inspiring that I included it in the Weekly Robotics #34 that is live since 30s ago (https://weeklyrobotics.com/weekly-robotics-34 https://weeklyrobotics.com/weekly-robotics-34).
For anyone interested here is a link to the paper: https://arxiv.org/abs/1904.03815 https://arxiv.org/abs/1904.03815 . Having robotic arms for <$5k would be great for research, hobbyist and applications not requiring crazy accuracy. I don't have hard data at hand but I doubt that at present you can find commercially available robot with similar characteristics for less than $15k.
Another thing that's happening here and I really enjoy is how BLDC motors are being used in applications like these. The reason I like it so much is because hopefully there will be a market for cheap actuators that will do the job well enough to be used for some applications. I'm pretty sure that among other things I've seen a lot of BLDC based actuators on quadruped robots.
- mtw 8y agoAre there any "hobbyists" who can afford a robot arm at $5k?
- lnsru 8y agoThere are already quality German robot kits for 5k: https://de.rs-online.com/mobile/p/roboterarm-montagekits/1765631/ https://de.rs-online.com/mobile/p/roboterarm-montagekits/176...
- pauljurczak 7y agoThe specs are much lower - you get only 5DOF for $5,600, instead of 7DOF. Igus is working on their ReBeL arm, which may be a more competitive option.
- lnsru 7y agoIs there any specific application, that needs 7DOF and cannot be done any other way? I guess, that Igus will give you other price when you ask them directly and 50 pieces. I am not related to them, but I like their approach. Plus I have no problem controlling stepper motors directly.
