Abstract

The RC vehicle comprises 4 crucial subsystems: the chassis, drivetrain, suspension, and steering. This paper will cover the chassis and drivetrain, and my partner Noah Stevens will cover the suspension and steering. The chassis serves as a robust framework housing all vehicle components, while the drivetrain transmits power from the motor to the wheels, propelling the vehicle. An efficient drivetrain typically sacrifices speed for enhanced torque, aiming to minimize energy losses. Meanwhile, an ideal chassis features minimal deflection and user-friendly mounting points. This RC vehicle participated in the CWU RC Baja competition, aiming to rank among the top contenders.

The student conducted a range of analyses that formed the basis of their engineering project. Statics, Mechanical Design, and Dynamics were the primary methods employed in the report. These analyses served to guide the student in designing parts to meet specified requirements when assembled. Following the design phase, manufacturing took place utilizing CNC machines, a Horizontal Bandsaw, Lathe machine, Mill machine, and 3D printing. Subsequently, the testing phase commenced, during which the student evaluated how well the vehicle's components met the testing criteria.

The project resulted in a fully functional vehicle capable of competing, and potentially excelling, in the RC Baja competition. The vehicle demonstrated great acceleration, braking, and maneuvering abilities in both forward and reverse directions. Both the suspension and chassis proved resilient, enduring the challenges presented during both the competition and testing phases. Notably, from a stationary position, the vehicle achieved a top speed of 25mph within a 50-meter distance.
