Units: Mostly "holes" - 0.5" module of the VEX metal.

Torque: How would gravity affect your tray when fully loaded with cubes, laying horizontal, only attached by its bottom hinge. Can be measured as such - on a detached horizontal tray with a Newton-meter (or a scale) supporting the tray at 1 meter from the bottom hinge.

Delta-x/y - distance between the tray bottom hinge and the axle of the driven arm.
