Roaches Inspire Robotics
Amir Ayali
Tel Aviv University researchers are studying the way cockroaches move to develop more advanced robotic technology. Although robots have been based on cockroaches in the past, the walking techniques have been influenced by outside observation, instead of internal mechanics. The researchers want to develop new robots that have a more compact body structure and are more energy efficient.
"Not only do cockroaches arguably exhibit one of the most stable ways to walk, called a tripod gate, but they move equally quickly on every kind of terrain," says Tel Aviv professor Amir Ayali.
The researchers are studying the cockroach's nervous system to determine how sensory feedback from one leg influences the coordination of the other legs. Robotics researchers also are gaining inspiration from other types of insects. Scientists are studying the aerodynamic build and metabolism of locusts to develop robots that can fly great distances.
Ayali says other researchers are studying caterpillars to develop soft-bodied robots that have endless degrees of freedom of movement.
