Abstract: A robot control system on a platform which can carry target objects employs a coordinate system including X, Y, and Z axes. A plane including the X and Y axis is parallel with a panel including the platform. After the coordinate system is created, a reminder is displayed and a guiding tool is placed in a position on the platform where the target objects are located, and a fastening tool for use with the guiding tool is arranged on hand of the robot. A location of the fastening tool relative to the guiding tool is adjusted according to a predefined rule. When the location of the fastening tool relative to the guiding tool is correctly adjusted, a position of the end effect of the robot is determined according to the location of the fastening tool and the relevant coordinates are stored as data.

Abstract: A positional stop device includes a base body, a lever, a driving element, and a retaining member. The lever is rotatablely arranged on the base body, a first end of the lever couples to the driving element, and a second end of the lever couples to the retaining member. The driving element is partially exposed out of the base body. The retaining member is moveablely received in the base body. When the slider of a pneumatic rodless cylinder slides along a first direction, the driving element is driven by the slider to move along a second direction and be fully received in the base body. The lever is driven by the driving element to rotate around the base body. The retaining member is driven by the lever to move along a third direction and to be partially exposed out of the base body to stops the slider from sliding.

Abstract: A testing apparatus for testing a circuit board is disclosed, which includes an upper plate, a lower plate, and an adaptor circuit board. A plurality of positioning units is received in the lower plate. Each positioning unit has a plurality of length-variable test probes secured therein. Each test probe has a shell and upper and lower probe ends at opposite ends of the shell. In test, the circuit board is put on the lower plate and the upper plate is lowered to push the circuit board and the lower plate toward the adaptor circuit board. The upper ends of the test probes engage with electrical connectors of the circuit board and the lower ends thereof engage with the adaptor circuit board whereby test of the circuit board can be automatically performed by the testing apparatus.

Abstract: A cylinder includes a curved cylinder body, a first support member, and a piston assembly. The curved cylinder body defines a gas chamber passing through opposite ends. The first support member includes a support housing slidably mounted on the outer circumferential surface of the cylinder body and a first permanent magnet securely mounted in the support housing. The piston assembly received in the gas chamber includes a first piston member and a second piston member rotatably coupled to the first piston member. The first and second piston members respectively have a second permanent magnet which is arranged to be attracted to the first permanent magnet. When the piston assembly moves along the curved cylinder body from the first end to the second end in the gas chamber, the first support member moves with the piston assembly on the outer circumferential surface of the curved cylinder body.
