specific Embodiment approach 1

[0006] Specific implementation mode one: as figure 1 with figure 2 As shown, the wrist-metacarpal joint detection mechanism 100 includes a potentiometer base 29 , a left bearing cap 30 , a right bearing cap 31 , a linear bearing 32 , a major axis 33 , a potentiometer 18 , and a ball buckle 34 . The shaft of the first potentiometer 18 is affixed to the bottom of the potentiometer base 29 by screws 36, and the hole seat on the vertical surface of the potentiometer base 29 is affixed to the second potentiometer 18 by screws 35. The shaft of the second potentiometer 18 is fixedly connected with the left bearing cover 30 by screws 36, and the linear bearing 32 is fixed by the left bearing cover 30 and the right bearing cover 31 by screws 36, and the long axis 33 is inserted in the linear bearing 32, so The long shaft 33 is in a sliding connection with the linear bearing 32 , and one end of the long shaft 33 is fixedly connected to the ball stud 34 .

specific Embodiment approach 2

[0007] Specific implementation mode two: as figure 1 with figure 2 As shown, the thumb metacarpophalangeal joint motion rod detection device includes a thumb metacarpophalangeal base 5, a thumb proximal knuckle base 4 and a thumb distal knuckle base 3 hinged sequentially with the palm base 102, each adjacent Potentiometers for measuring joint movements are installed at the two base hinges of the thumb to detect the angle and state of each knuckle movement of the thumb. The thumb metacarpophalangine base 5 is fixed on the thumb metacarpophalangine of the human hand, the thumb metacarpophalangine base 5 adopts a "C" shape to surround the thumb metacarpophalangine, and the opening faces the side where the thumb is connected to the palm. The base is provided with a rocker F at the back of the metacarpal knuckle of the thumb, and a hole G at the outer side. The rocker F of the thumb metacarpophalangeal joint base 5 is connected to the wrist metacarpal joint detection mechanism 1...

Abstract

The invention discloses a rod type detecting device for thumb metacarpophalangeal joint movement and relates to a data glove for detecting human hand finger movement states. The device attached to the exterior of a human hand to detect joint movement is designed in order to overcome the defects that an existing data glove sensor is high in price, complex in system, difficult to maintain and the like. A unique connection way and an ingenious joint measurement point layout are adopted, and obstructions and influences of a detecting mechanism on finger movement of an operator are reduced or eliminated, so that when the operator uses the device, finger movement can keep flexible and dexterous to the greatest degree, all joint movement states can be precisely detected, finger joints of a controlled slave hand and corresponding finger joints of the operator act synergistically and consistently, and multi-degree-of-freedom complex control over the slave hand becomes visual, simple and convenient.

Description

technical field [0001] The invention relates to a data glove for detecting the angle and state of human finger joint movement. Background technique [0002] Due to the development of science and technology, robots are gradually being used in an increasing range. As a reliable and mature robot, teleoperation robots are widely used in various dangerous, complex and inaccessible environments. It uses a very reliable control method, which is directly controlled by the operator's instructions. As the tasks performed by teleoperated robots become more and more complex, people put forward higher requirements for their flexibility while pursuing reliability, and it is necessary to implement teleoperation on complex manipulators to control the movement of multiple fingers of the manipulator. Multiple joints move in coordination to achieve specific functions, which requires the use of data gloves. Data gloves are the most effective device for teleoperating the robot's manipulator. It...
