Publication number: 20180164170Abstract: Collision of a robot is detected by the following method. The robot includes a motor, a gear reducer connected to the motor, an encoder detecting a rotation of the motor, a temperature sensor installed to the encoder, and an object which is driven by the motor via the gear reducer. An external force torque due to a collision as a collision torque estimation value is estimated by subtracting a dynamic torque obtained by an inverse dynamic calculation of the robot from a torque output to the gear reducer by the motor. It is determined that the robot receives an external force if the collision torque estimation value is greater than a predetermined collision detection threshold. The predetermined collision detection threshold is set to a first value in a case where a temperature detected by the temperature sensor is less than a predetermined temperature threshold.Type: ApplicationFiled: August 24, 2016Publication date: June 14, 2018Inventors: HIROYUKI NAKATA, ATSUMI HASHIMOTO, RYOSUKE YAMAMOTO, YASUYOSHI HONUCHI
