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.

Abstract: An oil-water separator with an oil discharge outlet adjusting spontaneously includes a liquid storage tank with grease and wastewater, a telescopic pipe in the liquid storage tank, and a floater unit connected with the telescopic pipe. The liquid storage tank comprises an inlet for grease and wastewater input, and a water outlet for wastewater output. The floater unit comprises at least one floater floating between grease and wastewater, and an isolation member extending in the height direction between the floater and the telescopic pipe. The isolation member fluctuates along with height changes of wastewater and includes an oil discharge outlet for grease entering the telescopic pipe. Therefore, an oil outlet, adjusting height spontaneously, is configured by the at least one floater, such that the overall height is reduced, a sufficient difference of levels of grease and wastewater is generated by the isolation member, thereby improving the oil-water separation effect.

Abstract: An oil separating apparatus includes a preliminary separator and a main separator. The preliminary separator is for collecting wastewater. The main separator has a main separating chamber, a wastewater exit channel and a communicating channel. The main separating chamber communicates with the preliminary separator, and has upper and lower openings. The communicating channel communicates the wastewater exit channel and the lower opening. A distance between the upper and lower openings ranges from 300 millimeters to 3000 millimeters.

Abstract: A massage chair includes: a base unit; a rocker mechanism including an actuator that is coupled to the base unit, at least one output bar that is connected pivotally to the base unit, an input bar that is connected to and that is driven rotatably by the actuator, and a connecting bar that is connected pivotally to the input bar and the output bar; and a seat unit connected immovably to the output bar. The input bar, the output bar, the connecting bar, and the base unit cooperate to constitute a crank-rocker planar four-bar linkage. The actuator actuates rotation of the input bar, which in turn drives reciprocating swing motion of the output bar and the seat unit.

Abstract: An oil extracting apparatus includes a rigid oil adhering ring having a horizontally disposed ring axis and an oil adhering surface surrounding the ring axis, a driving device coupled to the oil adhering ring for driving rotation of the oil adhering ring about the ring axis, an oil scraping unit, and an oil collecting unit. At least a portion of the oil adhering ring below the ring axis is adapted to be immersed in a water body. Rotation of the oil adhering ring results in separation of the oil from the water body and in adhering of the oil on the oil adhering ring to form an oil film on the oil adhering surface of the oil adhering ring. The oil scraping unit scrapes the oil film from the oil adhering surface of the oil adhering ring. The oil collecting unit collects the oil scraped by the oil scraping unit.

Abstract: A hydro-massage device for a bathtub includes a first water conduit unit in fluid communication with an inlet unit of a main pump and having a water inlet unit adapted to be disposed in the bathtub and adapted to be in fluid communication with a water source such that the main pump is filled with water from the water source when the water is supplied to the first water conduit unit via the water inlet unit, and a second water conduit unit in fluid communication with an outlet unit of the main pump and having a nozzle end that is adapted to be disposed in the bathtub. Water spouts are formed at the nozzle end when the main pump is activated. A control unit is operable so as to drain water from the main pump via one of the inlet and outlet units after deactivation of the main pump.
