Sevylor SBM 12 Volt Motor:
These are the main thrusters for the sub
BasicX 8 servo motor controller
Vantec RET411P Single Controller
To control the thrusters, we are using the Vantec Speed controller. This particular speed controller is operated by the same signal a servo motor, so the BasicX servo motor controller is also employed. The servo controller communicates with the on-board computer by serial connection. Since the speed controller acts a lot like a servo motor, we theoretically have 255 speeds. In reality there are less, but there is still a good range. This has proved to be a very cost-effective solution.
