What Are the Force Sensor Terminal and Block on PHU-F/RHU Drawings?

The terminal in front of the output side on the drawing is the force sensor interface. The block beside the drawing will be removed in the future. The two dowel pins on the drawing are for reducer and force sensor alignment, also planned for removal as they may cause noise.
The rear control board connects to the force sensor — one module corresponds to one force sensor, each independently controlled.
