Robots I have helped build:
This 4 wheel drive robot was built at KES school to take part in the Pi Wars challenge. The Chassis and motors are an Initio kit from 4Tronix, with ultrasonic sensors at the front, Infra red wallsensors at the side and infrared line following sensors beneath. A number of servo controlled attachments could be added to carry out specific functions, as well as a colour camera.
The processor was a Raspberry Pi, which as well as performing a number of autonomous challenges, could be driven by remote comtrol using a wireless gamepad. This robot competed at Pi Wars in 2018 and came 17th out of 35 schools.
