One joystick station

The right station of the two-joystick assembly, which is the un-mirrored one; the left station is its mirror image and takes the left harness.

One station

Exploded

Parts on the lever axis move along it: the lever and the gears forward, off the motor mount plate; the brake, motor, couplers, torque sensor and its plate back. The limit switch lifts off the plate; the stage interface plate, the linear stage, the rotation plate and the base move down. The order of each part is the registry's explode field; the distances come from the parts' sizes, so that at 100 % no two parts intersect. Fasteners, bearings and the ServoCity shaft hardware are omitted from these three views; the frame standoffs stay with the motor mount plate and the parts slide along them.
