  • Robot diagnosing method
    Patent number: 10020216
    Abstract: A robot diagnosing method of detecting a deviation amount caused by a lost motion includes: a first step of preparing a robot and a line sensor, the robot including a robot arm including one or a plurality of joint portions including a first joint portion, the line sensor including a detecting portion configured to detect a position of a detected portion based on a light receiving state of a light receiver, the detected portion being inserted between a light emitter and the light receiver; and a sixth step of detecting the deviation amount caused by the lost motion at the first joint portion based on (i) the position of the detected portion based on the position of the detected portion detected in a third step and a command value from a robot control portion in a fourth step and (ii) the position of the detected portion detected in a fifth step.

  • Substrate conveyance robot and operating method thereof
    Patent number: 10014205
    Abstract: A substrate conveyance robot has an end effector provided to a robot arm and including a substrate holding unit configured to hold a substrate, arm drive unit configured to drive the robot arm, a robot control unit configured to control the arm drive unit, and a holding force detection unit configured to detect a substrate holding force exerted by the substrate holding unit. The robot control unit controls the arm drive unit based on an upper limit value of at least one of acceleration and speed of the end effector which are determined in accordance with the substrate holding force detected by the holding force detection unit.
