In any ROV, the electronic systems frequently run in tandem with the hydraulic, mechanical, and control segments of a system. It is the brain of the ROV. It controls everything. Sensors, electric motors, power sources, etc. are crucial parts of an ROV. When, control system has to manage the vehicle while operating through a much simpler and more intuitive interface in order to operate the vehicle. A basic control of direction and proportional scaling of electrical motors is necessary to finely control the motion of the ROV. It is evident that all the electronic systems are necessary for the smooth running of an ROV.
