Abstract
Abstract An industrial robot has a control system with a program memory. During programming, the robot is manually controlled to a sequence of desired positions. At each position, an operating member may be activated to store into the program memory an instruction containing both information about the robot position and information about robot operation at that position. Suitably information about robot operation is entered in the form of identification of a sub-program containing a set or sequence of control signals which have been stored in advance. The sub-program is suitably identified by a number fetched from a buffer memory. For each of the instructions, during the execution of the main program, on the one hand the positioning of the robot is executed and, on the other hand, the sub-program is called and executed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
222 words
In an industrial robot control system for controlling the positioning of a robot to a number of programmed operating positions and the execution of programmed operations in association with these operating positions, the control system comprising: first control means for positioning, during programming, the robot successively to said operating positions and for storing, at each operating position, information for positioning the robot to that operating position and information for controlling an operation to be carried out in association with that operating position, first memory means for storing information fed in via the first control means during programming, said information comprising a main program with a sequence of instructions which, during automatic operation of the robot, are successively executed; and second control means for controlling the robot during automatic operation in accordance with the information stored in said first memory means; the improvement wherein: the control system comprises second memory means for storing information defining a sub-program, which contains information for control of one of said operations; the first control means comprising an operating member arranged, upon a single activation during programming with the robot at an operating position, to cause storage in the first memory means of an instruction which, during automatic operation causes positioning of the robot to that operating position as well as calling for an execution of said sub-program.
Claim 2
Dependent Claim
