ABSTRACT
The objectives of the mini-Baja competition are to design and manufacture a “fun to drive”, versatile, safe, durable, and high performance off road vehicle. Team members must ensure that the vehicle satisfies the limits of set rules, while also to generating financial support for the project, and managing their educational responsibilities. This vehicle must be capable of negotiating the most extreme terrain with confidence and ease. The 2012 SRM UNIVERSITY Mini-Baja Team, THE CONRODS met these objectives by dividing the vehicle into its major component subsystems. By examining the 2011 entry, the team was able improve on many design features to better meet the stated requirements. Function Diagram (QFD) to determine which parameters were the most critical. These key parameters ranging from most critical to least critical are safety, reliability, low cost, ease of operation and maintenance, and overall performance.
