OpenScout is a low-cost open source hardware and software mobile
robot that can be used for both indoor and outdoor tasks, transporting
up to 15kg of payload. It is designed to be easily and cheaply (350USD)
buildable and modifiable by non-specialists, and to function as a new
standard physical platform for robotics research and real-world tasks, re-
placing current proprietary options. It uses four-wheel differential drive
steering, and a hinged body which enables the wheels to drive over small
obstacles without the need for suspension
