Our company has been working on an autonomous rhino which can be driven by an onboard computer (rhino drives itself), driven by remote control or driven by a person onboard. Recently, we have added an electronic shifter which replaces the mechanical mechanism. Photos and updates of our progress can be found at http://www.brocktechnologies.com/Web%20Pages/Unmanned%20Ground%20Vehicles/ARGV/ARGV.htm .
Soon we will be taking this vehicle to the Yuma Sand Dunes for Testing and Demonstrations.
