Unit 2: Motors, Control Box and Testing

Description: Chris Hansen, SeaPerch Technical Director, with Fiona Redman and Gwen Gray will walk you through completing your SeaPerch build.

In this unit, you will waterproof the motors using wax, install propellers, waterproof the tether cable and mount the thrusters onto the frame. You will also build the ROV's control box by mounting electrical components on a printed circuit board, assembling and connecting the power cord, and mounting the circuit board in the plastic control box. Finally you will balance your SeaPerch.
