@youliangtan thanks for the question! Impedance control is something that we're interested in implementing at some point, but we currently don't have any documentation on it.
To enable current-based positon control, you would set the operating_mode
parameter to current_based_position
.
You can find information on the motor control loop for current-based position control here. In current-based position control mode, you can use the Goal_Current register to set current limits.
I'll keep this issue open until we have more details on this subject.
Question
As the title said, i would like to have a "impedance control"-like behavior for the the interbotix arms. However given most of the use cases here are pos/vel control without having force information. Having a force control robot manipulator is very important for most contact-based manipulation tasks.
I noticed that I can also use current_based_position_control for such behavior. How should i configure the config.yaml file? Not sure if there's any advice on this.
AFAIK, the effort/current from dynamixels can be quite noisy, thus it might not work as well as intended. Would like to get some advice on this.
