It looks like an ordinary four-wheeled recreational vehicle until you take a closer view. The wheels are triangular shaped. The Army is trying out four triangular wheels, designed by the Japanese, for possible use on robotic or other vehicles.
Initial reports indicate added stability and mobility.
This technology evaluation is being conducted by engineers at the Missile Research, Development and Engineering Center. In 1995 as part of an international cooperative exchange with Japanese industry, engineers here saw a set of triangular wheels demonstrated on videotape by Suzuki Motors of Japan. They were impressed at how these prototype wheels enabled a small vehicle to traverse rugged terrain. The Japanese developed triangular wheels for use on rice-paddy tractors. The experimental wheels were delivered in September 1997.
