Overview
This is a diagram showing all the physical components of our robot. Click for enlarged view.
PCB
The PCB on our robot performs several functions. It supplies power to all parts of the robot and also incorperates the H-bridge motor control circuitry. Our robot requires 3 different voltage levels to operate. The microcontroller runs on 3.3V, The … Continue reading
Wheels & Motor
The wheels and motor for our robot were taken from a RC car. This was chosen because the motor was already connected to drive both rear wheels. Additionally the front wheels were already attached to hinged mounts, allowing for easy connection to the … Continue reading
Sensors
Our robot incorporates three main sensor systems: the laser / webcam triangulation sensor, the IR rangefinders and the IR reflectance sensor. The primary sensor consists of a class 3 green laser mounted on the front of the robot. The reason for choosing a green … Continue reading
Chassis
The chassis of our robot is a four wheeled design. The rear wheels are used for propulsion, while the front wheels are for steering. This design was chosen over a differential drive system because it allows for greater speed. The propulsion motor … Continue reading
