09808934 · 2017-11-07 · ·

A robot control apparatus includes a stop command unit which stops a robot. A first external force judgement value smaller than a stop judgement value and a second external force judgement value smaller than the first external force judgement value are previously determined. The stop command unit inhibits a restart of execution of an operation program when, in a state where the execution of the operation program is temporarily stopped, an external force is continuously equal to or less than the first external force judgement value during a period of a first time length, and additionally, the external force continuously exceeds the second external force judgement value during a period of a second time length.

Automatic assembling system

An automatic assembling system, comprising: a robot performing an operation of inserting a first member into a second member; a force sensor for detecting an insertion force exerted on the first member by the robot; and a controller for controlling the insertion force with a closed-loop feedback control according to a difference between the insertion force detected by the force sensor and a predetermined insertion force, so that the insertion force is less than the predetermined insertion force to protect the first member and/or the second member from damage due to an overlarge insertion force. The present invention also is directed to a method for automatically assembling a product.

System and method for automatic error recovery in robotic assembly

A system for controlling a robotic arm performing insertion of a component along an insertion line accepts measurements of force experienced by the wrist of robotic arm at current position along insertion line and determines probability of value of the force conditioned on the current value of the position according to a probabilistic relationship for the force experienced by the wrist of the robotic arm along the insertion line as a probabilistic function of the positions of the wrist of the robotic arm along the line of insertion. The probabilistic function is learned from measurements of the operation repeatedly performed by one or multiple robotic arms having the configuration of the robotic arm under the control. The system determines a result of anomaly detection based on the probability of the current value of the force and controls the robotic arm based on the result of anomaly detection.
