Walker using spring actuators Print

A robot with a bizarre walking gait has been developed by Bill Bigge from the University of Sussex.




"This is a simple demonstration of how programmable spring actuators can be used to create a set of robot legs with in-built stepping reflexes. The robot 'walks' when it is pulled along on its leash. All the behaviour is embedded in the actuators. When a leg is perturbed beyond a limit, the shoulder actuator sends a binary signal to the knee actuator, which lifts the leg off the ground. The leg drops back when it has swung forward far enough. When one leg takes a step it will also send a signal to suppress the stepping reflex in the other leg, which stops them both stepping at the same time. "
