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
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
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
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
The microcontroller-based Receiver module measures just a bit over
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.
RF Control Receiver & Transmitter
Kits. Both kits require soldering.
