evatech
http://www.evatech.net/PRODUCTS.php?SELECTION=TREX TREX stands for Terrestrial Robotic Explorer. It uses Evatech's patented and proprietary propulsion technology. TREX is strong, fast, and reliable. Simplicity, combined with strength and intelligence are the key genes for a prevailing species and TREX has inherited them. It did not happen overnight; TREX is the result of 8 years of intellectual evolution and countless hours of experimentation.
