Latest Patents

Liu's latest patents include a "Screw tightening system, controller, and non-transitory storage medium." This innovative system features an actuator that rotationally drives a screw, coupled with a motor and a controller that manages the actuator's operations. The controller is equipped with an acquirer that gathers torque values generated by the motor, a calculator that computes the standard deviation of these torque values during a temporary tightening period, and a determiner that identifies abnormalities when the ratio of the standard deviation to a reference standard deviation surpasses a first threshold value.

Another notable patent is the "Robot system and method for controlling same." This technique automates the robotic assembly of two parts using a fastener structure. The system includes a robot that grips a workpiece, a force sensor to measure the force and moment acting on the workpiece, and a controller that oversees the robot's actions. The controller monitors changes in force and moment during the assembly process to determine the state of assembly effectively.
