The material of the tank car plate, drive wheel and bearing wheels are aluminum alloy, and the surface is oxidized, so it’s solid and durable. Using high horsepower DC motor, and equipped with high-quality Hall sensor, making it full of power. The tank car has some interfaces on the plate, such as Arduino UNO R3 installation port, 9g steering gear installation port, standard steering gear (such as MG996R, MG995) installation port and so on. In order to reduce the friction and make the tank run more smoothly, each of our shock-absorbing connections uses bearings (8 positions in total); and each load bearing wheel chooses two parallel rolling bearings to reduce friction. The tank car can be used for multi-purpose development platform, course design, robot competition, personal DIY and etc.
