  • Adaptive robotic nervous systems and control circuits therefor
    Patent number: 5325031
    Abstract: A self-stabilizing control circuit utilizing pulse delay circuits for controlling the limbs of a limbed robot, and a robot incorporating such a circuit, are provided. The pulse delay circuit acts as an artificial "neuron" which drives servo motors according to a selected sequence which is reconfigurable in response to signals from local or remote sensors. Also disclosed is a pulse neutralizing circuit which can be used to stabilize and reconfigure sequencing loops and chains incorporating the pulse delay circuit, and which can modify the actuation processes controlled thereby.
