The T100 Thruster is a patent-pending underwater thruster designed specifically for marine robotics. It’s high performing with over 5 pounds of thrust and durable enough for use in the open ocean at great depths. A variety of mounting options, simple control, and a low price tag make it the perfect thruster to use on your marine robot.
The T100 was designed for various consumers and limitless applications. Students and Schools can use the T100 for educational projects or to compete in competitions such as the AUVSI RoboSub and RoboBoat competitions and the MATE ROV competition. It’s capable and affordable hardware make it perfect for Makers and Hobbyists, as well as Professional Users who want a high-quality thruster that performs better than many of the high-end (expensive) alternatives.
The T100 is basically a brushless electric motor, just like you’d find on an RC airplane or a quadcopter drone. The big difference is that this motor is purpose-built for use in the ocean and was designed specifically for use on ROVs, AUVs, and robotic surface vehicles. Of course you could also use it to propel your stand-up-paddleboard or cruise around while kayaking! It’s compact design fits in any project.
The T100 is made of high-strength, UV resistant polycarbonate injection molded plastic. The core of the motor is sealed and protected with an epoxy coating and it uses high-performance plastic bearings in place of steel bearings that rust in saltwater. Everything that isn’t plastic is either aluminum or high-quality stainless steel that doesn’t corrode.
A specially designed propeller and nozzle provides efficient, powerful thrust while active water-cooling helps cool the motor. Unlike other thrusters, our design doesn’t have any air- or oil-filled cavities – water flows freely through all parts of the motor while it’s running and can handle extreme pressures.
The thruster is easy to use: just connect the three motor wires to any brushless electronic speed controller (ESC) and you can control it with an RC radio or a microcontroller. It’s usable with Arduino, ArduPilot, Raspberry Pi, BeagleBone, and many other embedded platforms.
The T100 comes with clockwise and counter-clockwise propellers to counter torque.

Always practice caution when you’re working with electricity in water and with the spinning blades of the propeller. Keep body parts away from the thruster inlet and outlet to avoid injury.
Do not operate the thruster for extended periods (more than a few seconds) out of water. The bearings are lubricated by the water and vibration and noise will be greater when dry.
Do not operate the thruster for extended periods (more than a minute) at full throttle in water. If not allowed to cool periodically, damage can occur. We recommend our T200 thruster for long period high throttle use cases.
The thruster can handle saltwater and sandy environments pretty well, but it does not get along with seaweed. Avoid sucking seaweed into the thruster to avoid damage.
