Abstract

The students in charge of the project, seniors at Central Washington University were tasked with the design and manufacturing of the RC Baja to compete in the Slalom and Sprint event and the Baja event where the maneuverability and acceleration are demonstrated. The project was divided between Roberto, in charge of the drivetrain and chassis and Rogelio, in charge of the steering and suspension. There were also various requirements like velocity and deflection, ensuring the device reaches 30mph and keeping the deflection of components to a minimum and many others which can be seen in section D of the introduction.

The RC vehicle was designed using various engineering methods using subjects such as mechanical design, dynamics and mechanics of materials to ensure that the device was going to meet requirements. The main manufacturing method was 3D printing as the intention was to keep the weight as minimal as possible. Once all manufacturing and analysis was completed, various tests were performed to gather data on various aspects of the vehicle like acceleration and velocity.

The 3D printed components were required to not exceed a deflection of .1”. The vehicle was expected to achieve a velocity of 30mph, and the suspension was calculated to compress .5” while the turning radius which was expected to be 4’. In summary, with the testing, it was possible to determine that the vehicle would be meeting the various requirements like the velocity and showed that it would also withstand the drop test as was intended.
