  • Patent number: 11478935
    Abstract: A method for a robot to automatically find a bending position, including the following steps: step 1, establishing a gripper tool coordinate system (TX, TY, TZ); step 2, determining a user coordinate system (XA, YA, ZA; XB, YB, ZB) of rear blocking fingers (11, 21); step 3, a robot gripper moving horizontally, and detecting the state of sensors (12, 22); step 4, the robot gripper executing a rotational movement, detecting the state of the sensors (12, 22), and thereby obtaining a standard bending position. The robot automatically finds the bending position, the teaching difficulty is reduced, and the bending quality is increased. In the elevator industry, elevator door plate bending sizes are the same, but forming sizes are different. In the present invention, only one product process needs to be taught in order to satisfy elevator door plate processing with different specifications, thereby reducing maintenance costs and increasing production efficiency.

  • Patent number: 9114529
    Abstract: A dual system component-based industrial robot controller having a standard operating system, a real-time operating system, a route management module, a soft bus, a driver management module, a motion control module, a PLC module, an IO module, a teach pendent interface module and a protocol stack module. The controller employs a component-based structure and the components are operated respectively under a non real-time standard operating system and a real-time operating system, and supports distributed processing. The communications and function calls among the components are carried out by the route management module and the soft bus. The components in communication are managed through the route management module. The driver management module provides communications among other modules with a consistent interface which accords to the DS402 standard, and a servo driver that accords to this interface standard can be readily integrated into the controller.

  • Patent number: 8152699
    Abstract: The present invention comprises an apparatus and method for gravity-balanced apparatuses for training humans for space exploration and other applications. The embodiment of the simulation apparatus is less expensive to build and safe to operate and adaptable to numerous applications, including but not limited to theme parks, museums, training facilities, educational/research labs, and others, for people to experience walking and other perambulations in lower or zero gravity environments. The present invention is statically-balanced and comprises a spring apparatus that is easily adjusted. An embodiment of the present invention provides an apparatus and method for simulating walking in a zero-gravity or reduced-gravity environment.
