Super Soaker ROV
In this example, the ServoShock is used to control a differential drive rover armed with a water gun. The wheels are controlled with the differential drive mixer that enables you to control both wheels on a differential drive vehicle with a single joystick. The turret is controlled with the other joystick set to the relative position mode.
The water gun is controlled by the trigger; the ServoShock is used to control a switch that turns the pump motor on and off.
