@@stepbystep-robotics6881 No worries! Your work is great, especially the 3D printed cyclodial gearbox, as I was looking to do something similar. I was wondering if I could ask you a quick question. Would be possible to do position control on the BLDC motors by using a cheap ESC and magnetic encoder running a PID loop? I have been looking at both the ODrive and Vesc and they are quite pricey.
@@stefanguiton I think it’s possible to do, but to control the BLDC we need FOC for precise control like position control, and that is implemented on Odrive and VESC as well. Honestly I haven’t tried make it from scratch because those open source controller already done that for us :) .
Is there somewhere where we can scale up the measurements for Watt's Linkage, almost like a calculator where you tell it what lengths you want one side to be and it tells you how long each length should be accordingly? If we were to make a robotic gripper ourselves?
yes, of course, the watt's linkage geometry is scalable under the constraint between links. So all the links could be multiple times bigger/smaller according to your design. You can try search on how the watt's linkage equation looks like. Good luck!
Yes, I think it’s possible. I did one with 4 fingers by using the same concept as one servo before. Please check on here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dRM77WZcJj8.html
Hard to say though...but there is no gear, so no contacting part, and lubricants, so I think it would last longer than usual gear base design :) because not much maintenance.
