Title: Motion controller containing its own producing function for action series
Inventor: YODA HARUO
IPC: G06N3/08
Filed: 1988-11-18
Abstract: PURPOSE:To facilitate the engineering control of a robot having the complicated actions by attaining a control system which detects and executes the series of complicated actions by its own function just with addition of a simple evaluation function. CONSTITUTION:The form and the attitude of a robot to be controlled are inputted to a control circuit in the form of the present states alpha, R and T. Thus the control circuit outputs the action values delta and alpha to actuate the robot in response to those states alpha, R and T. Under such conditions, a learning cycle is repetitively carried out while the changes of the form and the attitude of the robot are quantitatively evaluated with an evaluation function. Thus the control circuit is gradually taught to output the optimum values delta and alpha. Then a certain series of actions are automatically systemized into the parameter of the control circuit based on the evaluation function. As a result, the robot produces a desired action by its own function just with use of a proper evaluation function and then can execute the action smoothly. Thus it is possible to facilitate the control of the complicated motions of a control subject having a complicated structure.
