Robot system and method for producing to-be-processed material

摘要

A robot system (1) includes a robot (2), an operation control device (61), an impulse calculation device (63), and a first detection device (62). The robot (2) includes an end effector (23) and a force sensor (24). The force sensor (24) is configured to measure a force applied to the end effector (23). The operation control device (61) is configured to control the robot (2) to perform predetermined work. The impulse calculation device (63) is configured to calculate an impulse applied to the end effector (23) based on a measurement value measured by the force sensor (24) while the robot (2) is performing the predetermined work. The first detection device (62) is configured to generate detection information when the impulse exceeds a threshold.
