We are a private research and development firm in San Francisco's Mission district.
We could use some help on programming an automation system we are developing. The control and logic scheme is designed and just needs to be executed. BBB may be overkill but is common to other systems within the same machine. It is essentially controlling 2 motors. One is an open loop stepper motor, and the other is a Brushed DC motor driven in a current control scheme. The motion is set by the stepper motor to a simple constant acceleration and decel triangle profile, and the DC motor separately provides a modulated torque (via current). The calculation for the assist torque has a couple programmable coefficients and is quadratic in nature. Other than that, there are I/O's for initializing a move and setting distance, or E-stop, and a reset for a torque-assist variable. I think we have all the correct interposing drivers etc in place and just need help programming the board, but there's always room for improvement so open to improvement on the hardware architecture as well. Please let me know if you can help. This is a fun project. Also open to doing it on a different platform if its easier.
