DARPA: Hits, misses, and projects to watch

Projects to watch
- Robot cars: DARPA’s Grand Challenge competitions have aimed to foster the creation of driverless cars capable of traveling long distances across difficult terrain and even through busy traffic. Thanks to the competitions, some impressive vehicles have already been produced and it will not be long before DARPA robot cars are used in real military or civilian scenarios.
- Z-man: The aim is to allow soldiers to scale vertical walls without ropes or ladders at a rate of 0.5 meters a second. The solution: mimic the microscopic hairs, or “setae,” which allow geckos to stroll up walls and across ceilings. Small robots that climb using synthetic setae have already been demonstrated, but DARPA hopes to extend this technology to humans.
- Underwater express: Troop-transporting torpedoes could travel at speeds of up to 100 knots thanks to a phenomenon called supercavitation. This occurs when an object moves fast enough to vaporize the water around it into a single enveloping bubble. With virtually no contact between the torpedo and the water, drag is reduced by up to 70 percent. Tests so far have been restricted to unmanned drones.
- Bionic limbs: DARPA wants prosthetic limbs which are “fully functional, neurologically controlled and have normal sensory capabilities” and is funding scientists who are making serious progress. For example, Video of a bionic arm built by the creator of the Segway shows impressive dexterity, while other teams have built prototype prosthetics controlled by thought alone.
- Switchblade: DARPA has already revolutionized aerial warfare by encouraging the development of unmanned aerial vehicles (UAVs). The Switchblade should go further by becoming the first supersonic UAV capable of long-range missions. The $10.3 million project involves a bizarre design. The aircraft’s 61-metre wingspan pivots by 60° as it gains speed, until one wing points forwards and the other backwards enabling it to reach speeds of Mach 2.
- Exoskeletons: Think of an exoskeleton as a mechanical full-body upgrade. DARPA wants to increase the distance soldiers can march and the loads that they can carry with them. An exoskeleton developed by MIT with DARPA funding recently proved it could make a 36 kilograms load feel 80 percent lighter.
