Built by twin brothers, Geoff and Mike Howe of Barwick, Maine, the Ripsaw, unmanned ground vehicle, can careen at high speed [over 60 mph] over obstacles that would leave a vehicle’s crew dazed and bruised. It is operated by a driver in another vehicle using a modular crew station that can be unbolted and placed in a range of Army vehicles, including the Stryker and all the MRAP models. It is a cheap unmanned vehicle that is able to drive at the full speed of Humvees or other military truck convoys.
A weaponised version, modified by the Army’s Armament Research, Development and Engineering Center (ARDEC) at Picatinny Arsenal, NJ, includes a remotely operated M240 machine gun. The gun is operated by a separate person using another modular station that can be put in a range of vehicles. The Ripsaw can carry a payload of 2,000 pounds. It is not armored and each track can be removed as a unit should it be damaged. It was funded by an earmark worth about $1 million.
Coal Mine Personnel Carrier
Built specifically for subterranean operation, SR1 is ideal for coal and precious metal mining. The chassis is engineered out of 4130 chrome molly tubing to withstand the harshest of environments while offering extremely good fatigue resistance. The chassis is then further strengthened by completely webbing the tubular structure with .125″ plate steel. With 14″ of suspension, SR1 offers a smooth 6 person ride while also reducing the jarring forces throughout the frame. SR1 is engineered ground up to not only be the most durable mining personnel transport vehicle ever assembled but also to be extremely modular and easily maintained. Built with “over the shelf” parts, SR1 maintenance is simple and inexpensive. Powered by a tier 3 Cummins 4QSB, SR1 is powerful and emission certified for mining operations. SR1 is designed to replace the less reliable and more complex Humvee. It is also designed to be faster, more comfortable and less complex than current industry standard hydrostatic drive human transport mining vehicles
