Abstract

The goal of this project is to develop an RC car to compete in the MET RC Baja competition. A car will be constructed to be as lightweight, durable, and fast as possible while abiding by ROAR (Remotely Operated Auto Racers) regulations. As such, suspension, steering, chassis and drivetrain systems will need to be devised to form a complete vehicle. The chassis must provide mounting points for all other components of the vehicle and provide a rigid platform in order to create a stable vehicle. The suspension must operate smoothly, allowing for at least 1 inch of ground clearance, and allow the vehicle to transverse a variety of terrain including a 2-foot jump. The steering must be predictable, with less than 5 degrees of bump steer and allow for a less than 2 foot turning radius. These requirements will be achieved through extensive analysis and design of the suspension and chassis components. This project will focus on the suspension, steering, and chassis aspects of the RC car. The drivetrain aspects will be developed by teammate Rachel Krill. The analysis of all systems will involve static structural, kinematic, fatigue, and geometric analysis. The resulting vehicle is ROAR legal, can travel at speeds of 30mph, has approximately 1 inch of ground clearance, weighs 3.5 lbs, has a turning radius of less than 2 feet, and can complete all required tasks for the met RC Baja competition.
