Overview

Mechanical Design

Our robot was designed for robustness and reliability.

Electrical Design and Sensors

Motor Controllers

power FET

H-bridge

protection diode

Batteries

NiCd and Lithium options reasons we used lead-acid

Sensor Choice

bump sensors

break-beam

encoders

IR range-finders

gyro (or lack thereof)
