Abstract: The present invention relates to a parallel robot system, including: a control apparatus; a parallel robot, including a mounting base, a moving platform, and a driving apparatus arranged between the mounting base and the moving platform, where the driving apparatus is configured to drive the moving platform to make multi-degree-of-freedom movement relative to the mounting base, and the driving apparatus receives a control signal from the control apparatus; a tracer, arranged on the moving platform; a passive arm, where the mounting base of the parallel robot is connected to one end of the passive arm; and an optical positioning and tracking apparatus, configured to track a spatial position of the tracer in real time and to send spatial position data of the tracer to the control apparatus.

Abstract: The present invention relates to a robotic arm, including: an upper arm and a front arm; a first joint structure, by which the upper arm and the front arm are articulated together; a second joint structure, arranged at an end of the upper arm and/or an end of the front arm; a first driving mechanism, arranged in the upper arm; and a second driving mechanism, arranged in the front arm, where the first joint structure includes a first force amplification apparatus and a first locking element, the second joint structure includes a second force amplification apparatus and a second locking element, and the first driving mechanism and the second driving mechanism apply an acting force to the first locking element and/or the second locking element by the first force amplification apparatus and/or the second force amplification apparatus.

Abstract: A submerged floating rail transit system comprises a first rope (102), a buoyancy tank (103), a rail (104), a gear (108), a driving mechanism, a cable (110) and a second rope (111); wherein one end of the first rope is anchored to the water ground (101), and the other end of the first rope is connected with the buoyancy tank; the rail is provided on the buoyancy tank, the gear is engaged with the toothed rail of the rail, and a driving mechanism is provided on the rail; the driving mechanism drives the gear to move along the extending direction of the rail; the driving mechanism comprises a shell (105), a first motor (106), a second motor (107) and a rotating shaft (109); one end of the second rope is connected with the shell, and the other end of the second rope is connected with a ship (113) on the water surface (112); the first motor and the second motor rotate in the same direction to drive the gear to rotate, thus generating traction force, so that the driving mechanism moves along the extending directio

Abstract: Some embodiments provide an auxiliary system for take-off, landing, and carrying of a multi-rotor unmanned aircraft on a mobile platform. One system includes a base and a sleeve rod. The base is fixed on the mobile platform. The sleeve rod is inserted into an opening of the base and fixed on the mobile platform. An airframe is provided with a circular hole at a center portion, through which the sleeve rod is configured to pass. The cone sleeve on the lower side has a circular opening at a top portion fixedly connected to the circular hole. The cone sleeve on the upper side has a circular opening at a top portion. A sleeve is provided downward along the circular opening.
