Build a wireless RF controller for two SUMO Wrestler® Cars, DC motor vehicles or other robotics vehicles. Available as a Build Your Own® Kit (for advanced students) or buy already assembled. Kit versions require soldering and assembly and are for advanced students. Lab includes wireless controller,  hand controllers and  receiver boards. Optional Robotics Vehicle Base (not included) to build and experiment with sold separately (see above right). Gr. 9+.
Transmitters feature a 433MHz transmitting frequency for clear communication with no interference. One transmitter can handle up to two hand controllers controlling different vehicles. Each controller can control 3 motors and a solenoid. The first and second motor are assumed to be connected to the wheels and the controller can control forward, backward, left and right movements. For the third motor the controller can control the left and right direction of movement. The controller can turn the solenoid on and off. All these controls can be accomplished through a very simple and intuitive set of push button switches arranged in such a way that is easy to hold and operate.
The microcontroller-based Receiver module measures just a bit over 3”x2” in size. Screw terminals for the motors and the solenoid are used for easy access and modifications. Four bi-color LEDs visually indicate the state of each motor driver. A single switch selects one of the two available channels.
