This complete kit will allow you to build your own submersible Remote Operated Vehicle. The ROV moves in water and is controlled by a circuit board attached via a 6-foot cable. All necessary parts for assembly are included. Each kit comes with complete instructions on how to assemble the frame, motors, and propellers. Please note: this kit does require some soldering to attach wires to the motor assembly as well as to complete the control panel. Once assembled, three motors allow the submersible to move forward, backward, turn to port or starboard, and dive or surface. Requires 4 AA batteries (not included).
