Abstract

An object is to prevent automatic operation from being started while a monitoring function is in a disabled state. The present invention provides a robot system includes a robot, a control unit controlling the robot, and an operation monitoring unit having a monitoring function for monitoring contact or the possibility of contact between the robot and a peripheral object. The operation monitoring unit has a monitoring changeover switch that switches between enabling and disabling of the monitoring function. The control unit has a mode changeover switch that switches between a manual operation mode, and an automatic operation mode. The control unit performs control so as to inhibit the operation of the robot in a state in which the monitoring function is disabled and in which the operation mode is set to the automatic operation mode.

Claims3

Dependent claims

A robot system comprising:

a robot;
a control unit that controls the robot;
and
an operation monitoring unit that has a monitoring function for monitoring contact or the possibility of contact between the robot and a peripheral object;
wherein the operation monitoring unit is provided with a monitoring changeover switch that switches between enabling and disabling of the monitoring function;
wherein the control unit is provided with a mode changeover switch that switches between a manual operation mode, in which an operator operates the robot by using a portable operating panel, and an automatic operation mode, in which the robot is operated on the basis of a stored operation program;
and
wherein the control unit performs control so as to inhibit the operation of the robot responsive to determining that the monitoring function is disabled with the monitoring changeover switch and that operation mode is set to the automatic operation mode with the mode changeover switch.
