  • Patent number: 11958200
    Abstract: An automatic robotic arm system and a coordinating method for robotic arm and computer vision thereof are disclosed. A beam-splitting mirror splits an incident light into a visible light and a ranging light and respectively guides to an image capturing device and an optical ranging device arranged in the different reference axes. In a calibration mode, a transformation relation is computed based on a plurality of the calibration postures and corresponding calibration images. In an operation mode, a mechanical space coordinate is determined based on an operation image and the transformation relation, and the robotic arm is controlled to move based on the mechanical space coordinate.
    Type: Grant

  • Patent number: 11143576
    Abstract: A suspension aligning machine includes a bottom board, an intermediate board, a top board, actuation modules, a jig, and a control device. The intermediate board is mounted on a top of the bottom board by first supporting elements and has through holes. The top board is arranged above the intermediate board with supporting elements provided therebetween to have the top board floating and suspending above the intermediate board. The actuation modules are mounted under the top board and respectively extend through the through holes of the intermediate board and form a gap with respect to the bottom board. The operation of the actuation modules causes the top board to vibrate and incline and workpieces deposited in the jig mounted on the top board are caused to move in the jig and fall into the cavities of the jig to line up with each other and thus orderly arranged.

  • Patent number: 9844885
    Abstract: A gripping device comprises a base, a first finger rotatably or movably connected to the base, and a second finger connected to the base. The first finger and the second finger are capable of selectively entering an opened gripping mode and a closed gripping mode to grip an object. In the opened gripping mode, the first and second fingers grip the object from the same side of the object. In the closed gripping mode, the first and second fingers grip the object from different sides of the object.
