Human cooperative industrial robot with read-through function

摘要

A human-cooperative industrial robot includes a contact force detection part configured to detect a contact force applied to the robot when an operator and a robot come in contact with each other, a contact force monitoring part configured to either stop the robot or make the robot retreat in a direction in which the contact force is reduced if the contact force exceeds a predetermined threshold value, and an operation force detection part configured to detect an operation force applied to the robot when the lead-through operation is implemented. The robot also includes a lead-through switch for switching between the states of enabling and disabling the lead-through operation. When the lead-through operation is enabled, the contact force monitoring is disabled, and when the lead-through operation is disabled, the contact force monitor is enabled.
