Radio Control BAJA Car:
Drivetrain & Steering
PROJECT REPORT
PROJECT VIDEO
INTRODUCTION
The Radio-Controlled Baja car can be used in a contest, recreation, and/or for a sport. The end goal of this whole project would be to compete in an ASME Baja competition, which would be able to run obstacle course and time trails.
This half of the project will be a recording of designing, creating, and building a drivetrain system that will connected to a chassis.
The drivetrain's purpose is to provide power to the wheels, while the steering system controls the direction of the car.
Project Abstact
The purpose of the RC Baja Car is to compete in the American Society of Mechanical Engineers (ASME) competition, a series of events to prove the functionality of the vehicle. This series of events includes the Slalom, Drag, and Baja races. The Slalom is a test in the steering capability of the car. The Drag is a test in the acceleration of the car in a straight line. Lastly, the Baja puts all factors together in a race to test every component of the car. This project is about building an RC car that can function under these conditions and hit maximum performance capabilities. This report describes the analysis, design, construction, and testing evaluation of the drivetrain and steering systems of the car. Chesna Kern was responsible for the chassis and suspension portion; together, this makes a complete system. The drivetrain was built with two different gear ratio systems for the idea of being able to get high speed and get high torque. The steering was constructed with a high ratio servo and Lego pieces for easy change and adjustability. Using lightweight material was one of the most critical aspects of building, so most car parts used ABS and acrylic plastic to keep the weight low. The resulting car reached speeds of 10 mph, a turning radius of 30 degrees, and all weighed under 5 pounds. These were the critical factors that the car needed so that the event runs could be successful.
