Low-Signature Vehicle (LSV)

Technology Category: Mobile Robotic Platform

Description: The LSV (Low-Signature Vehicle) is a unique remotely controlled vehicle designed to perform subsurface characterization surveys at hazardous sites. Sensors such as magnetometers, ground-penetrating radar, a metal detector, and a radiation detector have been mounted on the vehicle to detect and map buried objects and materials such as hazardous waste or unexploded ordnance. The materials and components used in the construction of the LSV were largely nonmetallic to minimize the effects of the vehicle on the responses of the sensors.

The vehicle is based on a six-wheeled design with modified skid steering that allows it to maneuver around common obstacles such as bushes and trees. The chassis is articulated to minimize the movement of the instrument platform as the vehicle moves across rough ground. A pivot located on the vehicle's longitudinal axis allows the front and rear sections of the chassis to rotate relative to each other. Additional articulation is provided at the front end of the chassis. The two wheels on each side of the front section of the vehicle are mounted at the ends of a horizontal arm that pivots about a transverse axis. A gasoline engine powers a hydraulic drive train that provides torque at all six wheels. Embedded computers and radio telemetry units provide a control/data link to a nearby control station.
