Patent number: 11911891Abstract: An actuator system that picks up workpieces aims to shorten tact time and to reduce damages to workpieces. The actuator system includes an actuator that picks up a workpiece, an external force detection sensor that detects a physical quantity that is correlated with an external force that is applied to the workpiece, a head unit that is connected to the actuator and the external force detection sensor without a communication network, the head unit being configured to control the actuator based on a sensing result from the external force detection sensor when a pickup request signal that is a signal requesting pickup of the workpiece is received, and a control device that is connected to the head unit over the communication network, the control device being configured to transmit the pickup request signal to the head unit.Type: GrantFiled: October 17, 2019Date of Patent: February 27, 2024Assignee: THK CO., LTD.Inventors: Katsuya Fukushima, Masashi Ishii, Hiroki Niwa, Akira Suzuki, Kazuto Oga, Shogo Wakuta, Satoshi Hara, Tomofumi Mizuno, Shigeki Hayashi
