Abstract
A robot system capable of reliably detecting contact between a robot or a workpiece and an external object. The robot system includes: a robot including a handling part; a handling force-detection part that detects a handling force applied to the handling part; an operation controller that causes the robot to operate in accordance with the handling force; an external force-detection part that detects an external force acting on the robot; and a contact force-calculation part that calculates a contact force by subtracting the handling force from the detected external force.
