Američka agencija za napredne odbrambene istraživačke projekte (Defense Advanced Research Projects Agency - DARPA) razvija nekoliko platformi novog robotizovanog borbenog vozila sličnog koncepta.
Primarne odlike ovih vozila ogledaju se u izdržljivosti, visokoj mobilnosti i korisnoj nosivosti.
Sekundarne osobine koje ispunjavaju su - sposobnost prebacivanja u zone borbenog dejstva uz pomoć padobrana, visoka izdržljivost na udar, pouzdanost u eksploataciji kao i cena.
Sve platforme su robotizovane i bez ljudske posade.
Dve platforme koje se međusobno razlikuju samo u pojedinim detaljima i težini ( 7 i 6.5 tona)su Crusher i Unmanned Ground Combat Vehicle (UGCV) Spinner - vozila visoke prohodnosti, velike brzine i izdržljivosti.
Na promo-video snimku testiranja obe platforme može se videti neverovatna sposobnost savlađivanja i najtežih prepreka poput visokih stena, velikih rovova i izuzetno kamenitog terena gde savremena vozila točkaši i guseničari nemaju prohodnost.
Kada budu završena testiranja, a očekuju se uskoro krajem 2007 i 2008, na platforme će biti ugrađeno različito naoružanje u zavisnosti od potrebe.
Jedno je jasno - budućnost je već počela - ono što smo nekad gledali u naučnofantastičnim filmovima polako postaje stvarnost.

*Karakteristike vozila Crusher-
Crusher has a new space frame hull designed by CTC Technologies and made from high-strength aluminum tubes and titanium nodes. A suspended and shock-mounted skid plate made from high-strength steel allows Crusher to shrug off massive, below-hull strikes from boulders and tree stumps. The nose was completely redesigned for Crusher to sustain normal impacts with trees and brush while also absorbing the impact of major collisions.
Suspensions designed by Timoney support 30 in. of travel with selectable stiffness and reconfigurable ride height. Crusher can comfortably carry over 8000 lbs. of payload and armor. Crusher's hybrid electric system allows the vehicle to move silently on one battery charge over miles of extreme terrain. A 60kW turbo diesel engine maintains charge on the high-performance SAFT-built lithium ion battery module. Engine and batteries work intelligently to deliver power to Crusher's 6-wheel motor-in-hub drive system built around UQM traction motors.

*Karakteristike vozila UGCV (Spinner)-
As prime contractor, NREC managed the performance of over 30 trade studies, risk reduction activities, subsystem design and test activities. NREC also led all integration and assembly operations, and executed all performance testing. Additionally, NREC was responsible for many subsystems, including thermal management, prime power, ride height control, braking, safety, command station, OCU, communications, and teleoperation. Moreover, NREC developed all the vehicle positioning, automation, data gathering and data analysis systems that were used on a continuous basis to test the vehicle.
Following design, fabrication and assembly, Spinner completed two years of intense testing to assess its capability in a variety of terrains, weather conditions, and operational scenarios. For example, during a government-controlled field test at the Yuma, Arizona Proving Grounds, Spinner covered nearly 100 miles of very rough off-road terrain.
Overall, Spinner has traveled hundreds of miles on varied off-road terrains while under automated guidance, as well as under direct human control. Results continue to indicate that many of the technologies and approaches used in Spinner are viable options for UGVs in the future.
