Three-Legged Dogs Aid Robot Study


Balancing on three legs is tough for a robot.

Scientists have filmed and studied the gaits of three-legged dogs, in a bid to develop robot-building strategies. The researchers want to find out how the dogs compensate for the loss of a limb. They hope ultimately to develop robots that could compensate similarly. The scientists filmed the dogs from several angles with high speed cameras as they ran on treadmills.
