CMU and Boeing team on combat vehicle


The hybrid-powered, unmanned ground combat vehicle, Spinner, being built by Carnegie Mellon University (CMU) will be designed to negotiate and move swiftly over major terrain obstacles, withstand a moderate crash, and rapidly recover and operate while inverted. (Image courtesy of Boeing.)

The Defense Advanced Research Projects Agency (DARPA) has awarded $5.5 million to the National Robotics Engineering Consortium (NREC) of Carnegie Mellon University (CMU) to build and test a prototype robotic unmanned ground combat vehicle (UGCV). The vehicle will be the first attempt at an autonomous ground combat vehicle that can operate on all types of terrain. According to John Bares, Project Manager and Director of the NREC, CMU is "designing a new vehicle from the ground up that can take full advantage of the fact that it will not accommodate a human crew."

The award follows two earlier awards; the first to define the concept and the second for further detail design, in which a team of NREC researchers worked with subcontractors that included Boeing, PEI Electronics, and Timoney Technology to build a six-wheeled testbed machine similar in size to the final prototype.

The hull configuration of CMU's six-wheel drive Spinner will offer a large continuous payload bay that can rotate payloads in upright or downward positions. The vehicle will have a mass of about 7570 kg (16,700 lb) with full payload. (Image courtesy of CMU.)

Boeing is building the vehicle's frame, hull, nose, and payload compartment in Seattle, taking advantage of the latest composite materials and fabrication processes, together with a unique structural concept, that will be extremely crash resistant," said Wayne Hammond, Boeing UGCV Program Manager. Boeing's Unmanned Systems organization also includes the X-45 unmanned combat air vehicle and ScanEagle unmanned aerial vehicle.

Timoney, based in Meath, Ireland, is in charge of the vehicle's unique invertible suspension and wheel drive units that will enable to vehicle to operate upside down after a rollover. Huntsville, AL-based PEI, a business unit of Integrated Defense Technologies, will supply the vehicle's battery and power-management system and key vehicle control software and hardware.

High-torque, wheel-mounted propulsion motors from UQM Technologies will power the Spinner. According to William Rankin, UQM President and CEO, the company nearly doubled the torque delivery capability of its existing high-performance propulsion motors to meet performance requirements of the Spinner. The vehicle's final assembly will be by CMU in Pittsburgh.

CMU and UQM are also working together on the development and preliminary design of propulsion system for the future Gladiator tactical unmanned ground vehicle (TUGV). The TUGV is planned as a robust, compact, unmanned multipurpose vehicle system that will possess a scouting and direct engagement capability. The tele-operated, semi-autonomous vehicle will provide the U.S. Marine Corps with remote reconnaissance, surveillance, and target acquisition; nuclear, biological, and chemical reconnaissance; obstacle breaching; and direct fire capability to neutralize threats.

Nuvera Fuel Cells has launched a hydrogen fuel-cell business based on its Avanti 5-kW distributed generation product line. The initiative will provide OEMs with ruggedized hydrogen power modules ranging from 1 to 6 kW for operation under harsh conditions associated with industrial and automotive environments. Nuvera's strategy includes both reformer-based fuel-cell systems and hydrogen power modules. The company will continue developing fuel processors, fuel-cell stacks, and power electronics for the distributed generation and automotive industries, while leveraging its fuel-cell stack technology for hydrogen power module applications such as industrial vehicles, range extenders for cars, and uninterruptible power systems.

The BMW Group and PSA Peugeot Citroën have joined forces to develop and manufacture a new family of small gasoline engines. Peugeot, Citroën, and future variants of Mini vehicles (possibly up to 1,000,000 units a year) will be equipped with engines that will encompass the technology of the cooperative project. The Research & Development department at BMW will be in charge of designed the engines, and the common project team will be based in Munich. PSA will manage process development, engineering for production, and procurement.

Energy Visions Inc. has modeled a hybrid system using a combination of its proprietary technologies, the direct methanol fuel cell (DMFC) and nickel-zinc battery. The company's DMFC system operates directly on methanol extracting hydrogen without a fuel reformer. Using a golf cart as an example, the company believes the initial cost of its hybrid system would be competitive in price with the lead-zinc battery systems currently in use, weight half as much, and eliminate the downtime required to recharge.

General Motors' new Fuel Cell Development Center in Honeoye Falls, NY, will develop fuel-cell technology for commercial use, creating up to 100 new research and engineering jobs. Initially, work at the new facility will focus on developing fuel-cell stacks, fuel processors, electrolyzers, and the systems around them into products for both stationary and transportation uses. GM plans in the future to use fuel-cell power to operate many parts of the building.
