KARR uses a custom, microcontroller-based control system. A Propeller Chip is used on the ROV to control motors/lights and to read sensor data (planning on having a 9-axis absolute orientation sensor and a depth sensor). H-bridge circuits are used to control the ROV’s brushed DC thrusters. The topside controls consist primarily of a Propeller Chip and PS2 controller. These two microcontrollers communicate over the tether through a Blue Robotics tether interface board.
