 Broadly speaking it consists of a [[https://en.wikipedia.org/wiki/SCARA|SCARA]] robotic arm with two joints. One joint is at the centre, and one joint is at the midpoint of the arm. The arms are driven by a pair of stepper motors either side of the central axis. One axis is driven directly from one of the steppers. The other axis is driven via an idler pulley on the first axis to transmit the torque to the arm mounted on the second axis.
