Researchers from Carnegie Mellon University have built a rescue robot that can transform from human form into a tank. Known as CHIMP (CMU Highly Intelligent Mobile Platform), the robot uses its human form to do things like climb ladders and operate valves, and uses its tank form for handling tough terrain.

CHIMP was created by CMU for the DARPA Robotics Challenge. DARPA started the contest in response to the Fukushima nuclear meltdown, given the unpreparedness of rescue robots during that event. It seeks candidates as it searches for the next wave of rescue machines.

DARPA's top priority in finding the right robot is flexibility, allowing the machine to adapt to a variety of situations. CMU's CHIMP, a human/tank combo, appears to adequately meet this requirement.

"CHIMP will be able to perform complex, physically challenging tasks through supervised autonomy," CMU said in a news release. "A remote, human operator will make high-level commands controlling the robot's path and actions, while the robot's on-board intelligence prevents collisions, maintains stability and otherwise keeps the robot from harm. The robot also will be pre-programmed to execute tasks such as grasping a tool, stepping on a ladder rung or turning a steering wheel without step-by-step direction from the human controller, circumventing the lag between command and execution."

Those with images of robo-tank-chimps taking over society can rest at ease: the machine will require a human operator. And regardless of who wins the contest, CHIMP has already introduced some innovative new technologies, such as proprietary drive joints with human-like strength.

On Dec. 23, 2013 CHIMP will have a shot at proving itself at a DARPA competition during which robots will have to perform a variety of tasks, including driving a utility vehicle, traveling over rubble, removing rubble, climbing up a ladder and breaking through a concrete panel.
