  • Robot arm control method using open loop control in combination with closed loop control
    Patent number: 4488242
    Abstract: A method for controlling the locus of an arm of an arm type robot or the like, wherein a control system which drives a first arm of a two-joint arm under open-loop control and a second arm under feedback control is provided. A bang-bang drive system is used for positioning the first arm in a minimum time. The position of the tip of the second arm can be detected either from the rotational angle of each arm or by means of a position recognizing device. Furthermore, an arm positioning method for rapidly bringing the tip of a multi-joint arm to a desired position while detecting the positions of its tip and its joints by simple calculations is disclosed.
