Flip the Base over (as shown in Figure 5c), and attach each pre-assembled drive motor unit to the Base
using (2) ¼ x 20 button head screws for each motor, as shown. Tighten using a 5/32” Allen wrench.
Connect (2) long, three-pin servo extension cables to each of the Quadrature Encoder Boards. Be sure to
observe proper polarity, as noted on the Encoder board silk screen. Connect each of the other ends of
the cables to the Control Board when it’s installed. It is recommended that the cables are routed across
the top side of the robot platform.
