Merging man and machine: The exoskeleton-powered droid that can punch through walls

Tumbling tinmen

The Hermes droid has been designed to sidestep some of the common balance problems that affect humanoid robots.

The robot seen here was only one of many that took a tumble in this year's DARPA Robotics Challenge.

The difficulty bots still have with tasks such as climbing rubble or opening doors reflects the how hard it is for them to act like humans - even when remotely controlled.
