I am currently working on a project to add a second drive train to the BLUE ROV 2. This drive train will allow the ROV to drive along side a wall via tank treads. The end product will be allowing the ROV to swim using the pixarc controller and then drive along the sides of ships and stuff like that using the ps3 controller. I have already written python code to control the motors for the tank treads via PWM signals on the Raspberry Pi’s GPIOs using a PS3 controller. I am now looking for ways to send the controller signal through the tether so I can have my controller on land and connect to the raspberry pi via the tether. Any thoughts on how to possibly do this.
