Arduino Field Oriented Control (FOC) Haptic control example - SimpleFOCShield

This is a short video demonstration of simplified haptic control algorithms based on SimpleFOCShields and gimbal motors.
SimpleFOCShield is an open-source BLDC driver developed for Gimbal motors.

When I first saw servo motor synchronized their speed and position in exhibition decades ago. The manufacturer told me their product of sync for 2x15 kwmotors was roughly 20k $. Now it becomes hobbyist job. Excellent!!

[@leonardorui1646]

Excellent engineering case！ This haptic control can be used in large exoskeleton robots, which can easily lift a car or grab an egg without breaking it.

The throttle idea is great for bikes and cars as the car and user can get an idea of what they want

[@Blox117]

its useless for bikes because the motor already does that same thing.

[@After_Tech_Industries]

Do bikes have adjustable throttle sensitivity?

[@Blox117]

@@After_Tech_Industries yeah they do. but when riding you can always feel the difference

[@carterlynch4104]

@@Blox117 I think the electric bikes feel soulless. This could bring some life back.

[@warrenschoeberlein9271]

Excellent demonstration - the SimpleFOC Shields make complex control pretty simple to accomplish. Looking forward to your next video!

Amazing video. But unfortunately - very dangerous - it opens new ways and ideas for new amazing projects in my mind, which puts my current projects in jeopardy:-)

fuck yeah dude! xD

[@Buciasda33]

heh, I just started working on something great. How are your projects going?

[@GarranGossage]

Awesome work. So many possibilities!

[@CinemaEngineer]

Super cool. Thanks for sharing

[@Robinlarsson83]

In the second example, where you slowed down the smaller motor, it then stayed on the lower speed after you stopped touching it. I assume that is because the control knob (the other motor) has turned to indicate the lower speed on the small motor, but that also changed the expected speed value since the knob has moved, and thus the small motor stays at the lower speed. I guess it could be programmed to disregard encoder input from the knob if the motor in the knob caused the change in encoder input? If one would want the small motor in this setup to speed back up after you slowed it down :)

[@mgrpe]

Nice! 4 years is a long time in tech. What would be the updated hardware version for an equivalent project nowadays?

[@kesh2032]

This is amazing ! You inspire me ! Going to start working on this !!!

[@martinkeckes]

Hi everyone, I am new in FOC matters and especially interested in Steer by wire. I have used exactly the schema and sketch from the official Simple FOC. The problem is, it is not working at all. Both motors move a little just at the beginning, when I plug the system. But nothing more happens. I have 2 Simple FOC Shields V. 2.0.4. and right here are my pinouts: FOC Shield No. 1: Solderpoints: 5V, A0, A2, A5, 11,13, 3, 7, 10, 6 FOC Shield No. 2: Solderpoints: 5V, A1, A3, 12, 2, 4, 5, 8, 9, 11 Well, that is the best I could do...I have respected all the rules of configuration, I hope... I really did not know if or how to incorporate eventually pins for the AS5600 - I2C - sensor. Is this configuration wrong? Or what else is to be done, so that the system works like in your video? The schema and the sketch are exactly like on foc.com Thanks!!! Martin.

[@jcims]

Awesome demo! I'm really liking all of these bidirectional control examples. Do you have any issues with different encoder resolution or can you tune any effects out with the PID (?) loop?

[@alzalame]

Genius , nice and neat .

[@crashfactory]

amazing stuff! keep up the great work!

[@gsge]

Thank you for your efforts.

[@viggob4816]

Thank you showing this cool video with motor control. Do the motors you use have any cogging moments, or are the motors special made to keep cogging moments at minimum?

[@stefanguiton]

Cool examples! Great content

[@yousrialger]

Thank you

[@WoutStandaert]

This is awesome!

[@nialpmatk04]

can this be adjusted to be used as a throttle on a small boat thruster pod with say 1/4 throw forward or backward each direction and come back to zero when released like its spring loaded?

[@jcmtzros]

Hi, I have used exactly the schema and sketch from the official Simple FOC, Im trying with two different motors and encoders. Both motors move a little just at the beginning, when I plug the system. But nothing more happens. Let me know where can I send you images and videos.

[@NicksStuff]

This is soooo cool

[@GeorgeTsiros]

nice, nice

[@matyasmoudry2122]

How many motors can you control like this at sme time?

[@MrJob91]

would be so nice to ride a bike and feel the slope that you ride in throttle resistance

[@patriziozaccagnini5414]

What model of the motor is? And can you tell me the supply you used in this video?

[@aravinthkumar7924]

hi antun, good work.

[@tgirard123]

I'm curious about the motors you were using. Do they have much cogging? I've been trying to find motors that have minimal coging. More difficult than you might think. What were the make and model of The ones you were using?

[@viggob4816]

Hi. I just now asked basically the same question. I think it would be hard to make this behavior without using motors with minimal cogging moments. But it might also be possible to have some anti cogging calibration, that could reduce influence of the cogging moments.

[@Fahnder99]

bizarre and interesting!

[@matisssnikers9332]

amazing!

For simple FOC, It is not work with the bigger brushless motor.

[@vex123]

can you comment on whether there's any cogging?

Hi, is possible to apply a variable resistance to an external rotation as Tacx Neo bike trainer?

[@paytufo]

@@theskura Thank you! Yes, I know I just need one motor. Any code example?

[@GeorgeTsiros]

so, basically, you made the two motors (try to) obey a function f(pos_a, pos_b, time) = 0 🤓

[@amperemam5713]

It only works good until it fails...

Like everything else then? Nothing is perfect or has 100% uptime (without redundant systems).
