Bionic manipulator based on drive of electromagnetic muscles and tendons

The invention discloses a bionic manipulator which mainly comprises a palm (1), a thumb (2), fingers (3), muscles (4), tendons (5), driving motors (6), gears (7), rotating wheels (8) with gears, a manipulator surface (9), tendon position fixing rings (10) and muscle fixing rings (11). Each tendon (5) is wound around two ends of the corresponding rotating wheel (8) to be respectively connected to ends of the upper surface and the lower surface of the corresponding finger (3). Each rotating wheel (8) rotates to drive the corresponding tendons (5) on the upper surface and the lower surface of the rotating wheel (8) so as to change the lengths of the tendons (5), and various sections of the corresponding finger (3) are bent under the restraining action of the corresponding tendon position fixing rings (10). When the manipulator is required to act simply, only the tendons (5) need to be driven; and when the manipulator is required to grasp an article, the tendons (5) and the muscles (4) are driven simultaneously to work in a coordination manner (timing can be mastered by the aid of pressure sensors). When the manipulator grasps the article, each finger (2) with second-type joints is connected with the palm (1) by a spherical hinge, and the opening of each finger (2) is adjusted by contraction force of the corresponding muscles (4) on two sides of the finger (2), so that the manipulator is adaptive to the shape of the article. The thumb (2) can move in multiple directions by the aid of the corresponding muscles (4) in front, rear, left and right directions.

Human engineering vertical mouse capable of being mutually used by left hand and right hand

The invention provides a human engineering vertical mouse capable of being mutually used by a left hand and a right hand. The human engineering vertical mouse comprises a left half body and a right half body which are arranged in mutual symmetry. Each half body comprises an upper part and a base placed at the bottom of the upper part, each upper part is perpendicular to the corresponding base, a key face is arranged on the right side of each upper part, a hand placing face is arranged on the left side of each upper part, each key face is an outward-convex arc-shaped face, each hand placing face is an inward-concave arc-shaped face, and each key face is sequentially provided with a left key, an idler wheel and a right key from top to bottom. A main control single chip microcomputer is arranged in a mouse body, the main control single chip microcomputer is connected with left hand matrix keys, right hand matrix keys, a power management circuit, an optical sensor system, a signal sending circuit and a switching switch respectively, and the power management circuit is connected with the optical sensor system. The overall shape of the mouse can be well matched with a palm curve in a supporting mode when a human hand is in the most natural and relaxed state, a user can completely relax the arm and the wrist in the using process, muscle strain is reduced, the mouse can be used by the left hand and the right hand alternatively, and the habit demand for using by the left hand and the right hand of different people is met.
