Tron-Car RC Suspension and Steering Federico Berrospe, Alex Amadio Project Mentor(s): Jeunghwan “John” Choi, PhD; Charles Pringle, PE
Mechanical Engineering students at Central Washington University were challenged to build an RC car that can compete in the RC Baja race and the Slalom-and-Sprint competition. The car needed a suspension that could support the chassis and prevent it from deflecting and a steering that can provide directional control. The problem was solved by designing, manufacturing and assembling components for the suspension and steering mechanisms. For the suspension mechanism shock-towers and control arms were 3-D printed out of PLA. A dual arm double wishbone system was used to maximize wheel support. Shocks were connected to the wishbones and shock-tower to provide support. The steering was resolved by creating caster blocks and steering knuckles that attach to the control arms and wheels and provide a pivot for the wheels to steer. A bell crank connection was attached to the servo to convert rotational motion to linear motion. The bell crank was connected to the steering knuckle using tie rods to ensure the wheels stay parallel to each other when the car steers. The results led to a suspension that deflected an inch and prevented the chassis from touching the ground. The steering components were able to provide 35 degrees steering angles at high speeds. The project was able to provide an adequate solution and obtain a top 3 finish in the RC Baja race and the Slalom-and-Sprint competition.

With the increased usage of sustainable power generation systems used in our infrastructure today, demonstrations of these systems are necessary to allow many others to understand the importance of implementing them for our advancements. Being able to store this energy during times of high usage is also going to be necessary when we cannot meet power demands throughout the day. This project uses generators like solar panels and turbines, control components such as a DC converter and transistors, and LabVIEW which will be used to display an understandable series of power data. This demonstration will be helpful in teaching others to learn about green energy systems, such as solar power and wind power. While there are numerous studies out there about green energy, having an interactive and physical system, even on a small scale, can help others in understanding how power generation and distribution has a vital role in our infrastructure.
