In the KickStarter video we used an Espruino-controlled Robot, this is available from Olimex (see links below).
The kit contains the chassis, motors and wheels, but you still need something to control the motors.
- An Espruino Board
- A L293D Motor Driver IC soldered on to the board
- A HC-SR04 Ultrasonic Distance Sensor so that the Robot could sense the distance to obstacles.
