Chassis

A chassis is the fundamental rigid frame on and around which a robot is built.

Overview

The chassis consists of rigid members that together comprise a frame. It is on and within these chassis frame members that the components of the robot are installed, including drive trains, motors, pneumatics, electronics, and nearly everything else. It is important that the chassis be well-designed to keep everything together in a sensible way that does not inhibit mobility. Given the restrictions on the robot's design, the weight of the chassis must also be considered.

Materials

Many different materials can be used for the chassis, and the kit of parts provided basic chassis members in 2005 and 2006. These were prefabricated members designed to interlock via notch-shaped pieces and many holes that also saved weight. They were made of aluminum, which is very light and easy to work with while still being durable. Chassis members and frames can also be made of steel, which is heavy but extremely durable, wood, or plastic such as HDPE. The choice of materials is crucial to the effectiveness of a chassis design.
