Smart as these workarounds are, they're also a sign of the surprisingly slow progress of robotic manipulation. When details of the DRC were announced in 2012, driving seemed like an odd, but integral part of the competition. Battery power for large robots is scarce—more battery cells equals more weight, which is always problematic--and machines that respond to disasters shouldn't be burning their limited energy supply by walking, crawling or rolling for long stretches en route their destination. DARPA's proposed solution is simple: commandeer a vehicle. Human response teams at the edge of the disaster zone could help the bot into a vehicle, and send it into the fray. Once the robot couldn't drive any further, due to debris, or the need to go indoors, it would extricate itself and carry on using its built-in mobility. And by making driving and egress (getting out of the vehicle) two separate tasks, representing two out of a total of eight possible points that teams can score during the DRC Finals, DARPA further emphasized the competition's goal of developing robots that can function in environments that weren't specifically made for them. And since power tools were another part of the competition, you didn't have to be a roboticist to envision a bunch of machines with dextrous, human-like hands, similar to the five-fingered manipulators on NASA's Robonaut.
