Figure 1: Fully Assembled Vehicle

Introduction:

The R/C Baja competition is an annual event hosted by CWU ASME. Multiple teams will compete by designing and fabricating R/C cars that meet specified requirements, and putting them through multiple courses and tests. The objective of this project is to design and fabricate a fully functioning drivetrain and incorporate it into the chassis and suspension. Following this, the completed vehicle will successfully compete in all facets of the competition. 

 

 

Motivation:

The design and fabrication of a drivetrain/powertrain system is about as pure mechanical engineering as you can get. Mechanical engineers design, analyze, manufacture and maintain mechanical systems. A mechanical system manages power to accomplish a task that involves forces and movement. A drivetrain fits that bill very closely. While not a direct comparison, work on the R/C Baja will also provide valuable knowledge on the principle of vehicle design.

Results

The project resulted in the successful completion of a functioning R/C Car. The vehicles performance matched up well with the stipulated requirements and the predicted performance. The vehicle achieved a maximum speed of 20 mph, which was the minimum requirement as well as the predicted value. Additionally, the vehicle achieved a maximum acceleration of 6.9 ft/s^2 which was 36% more when compared to the stipulated acceleration requirement. This also matched up nicely with the predicted maximum acceleration value. Though these performance values were the most relevant to the success of the project, all other vehicle requirements were successfully met.
