Fast Force Feedback for Brushless Motor (ODrive + Arduino)

In this video I looked at the performance of the force feedback, which I implemented in the High Five Robot (check out my previous videos). During the communication between ODrive and Arduino most of the time is just taken to send the command to ODrive.I've changed the ODrive firmware to increase the communication speed by more than two times. And it works pretty well! So well that I even made some dangerous test :). Also I briefly explained how the encoder works.

This video is so underrated, my favorite video so far. Glad to know that I'm not the only one that spazzes out when their inventions work as planned!

Hi, It's a amazing aplication. Congratulations!!!! I want to ask you a question. I have purchased an Odrive v3.6, and I want to do a torque control of a BLDC motor, but set the control setpoint with a potentiometer. Then, to start the motor, I want to install a button, and another button to stop the motor. The questions are surely very silly for you, and I beg your pardon, but I still don't know enough about the Odrive device. How can I make this configuration? How should I program the Odrive to work under these conditions? Thank you very much and once again CONGRATULATIONS !!!

This is fantastic!!! I'm working on building an arm right now using a couple of ODrives. Where did you get that gearbox?

@Skyentific 5 лет назад

Thank you for your comment! I bought this gearbox around 5 years ago. This is planetary two stage gearbox with the reduction ratio of 32. Unfortunately this seller does not exist anymore on aliexpress. But on aliexpress you can find other similar gearboxes, try to search for "flange output planetary gearbox reducer for NEMA23". This is quite expensive gearboxes (starting from 200-300 dollars), mine was around 400 or 500 dollars.

goooooooooooooooooooood I respect to you~~~ thank you

@tinchodias 5 лет назад

Thanks! I really appreciated to watch your analysis and optimization of the communication between the Arduino and odrive. (My experience is more on programming and quite poor in electronics). I want to ask you about the time lapse between the moment when the Arduino program detects the arm stopped (the current raises, as you shown) and the moment when the program decides to go back with the arm. This time lapse looks like much more than few milliseconds in the video. BTW, I subscribed to your channel, thanks again.

@Skyentific 5 лет назад

Thank you. In the program when the high current is detected, first it put driver into the idle state (where the motor does not apply any force) and only afterwards it send the command to bring the arm in the initial position. Probably all these commands take some significant time. I did not analysed this yet in details.

sorry to be off topic but does any of you know of a method to get back into an instagram account? I was dumb forgot the password. I appreciate any help you can offer me

@CharlieRefvem 3 года назад

Have you tried upping the UART baudrate to something higher than 115200? You could probably shave off another millisecond by bumping up that baudrate.

@noffnoff96 5 лет назад

I think this would work quite well with a backdrivable gearbox (or even without a gearbox) if you tweak the stiffness (current/position gain etc). I do not have a lot of experience, so take this with a grain of salt. :)

@Skyentific 5 лет назад

This is very good idea. And I will try to do this. I have pulleys to make the gear ratio of 2 and 10.

@noffnoff96 5 лет назад

@@Skyentific Great! I'm excited to see how it goes. Best of luck :)
