To enhance their mechanical design and prototyping skills, engineering students at Texas A&M University Corpus Christi have built an off-road vehicle for the Basic Utility Vehicle (BUV) Competition. Some of the design details of the transmission, steering and braking system of this utility vehicle are presented in this paper, accompanied by computer generated drawings, simulations and photographs of the physical prototype.
