- | As our board cannot only control voltages fed to each motor, we must use a motor model to calculate these voltages. The block 'Motor Model' gets the actual speed and the calculated torque as input, and outputs the desired voltage for each motor. | + | As our board cannot only control voltages fed to each motor, we must use a motor model to calculate these voltages.
