Embodiment Construction

[0006] Such as figure 1 and figure 2 Shown, described thumb metacarpophalangeal joint motion detecting device comprises thumb metacarpophalangeal joint base 5, thumb proximal knuckle base 4, potentiometer 18, potentiometer cover 22, bearing 23, screw 24, connecting rod 26, rocking arm 27 and rocker arm 28. A potentiometer for measuring joint action is installed at the hinge of the thumb metacarpophalangeal joint base 5 and the thumb proximal knuckle base 4, for detecting the angle and state of the thumb metacarpophalangeal joint motion. 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. A hole seat G is provided on the outer side of the base. The thumb proximal knuckle base 4 is fixed on the thumb proximal knuckle of the human hand, the thumb proximal knuckl...

Abstract

The invention relates to a data glove for detecting finger movement state of human hands, in particular to a thumb metacarpophalangeal joint movement detection device, and aims to solve the problem that an existing data glove is high in sensor price, complex in system, difficult to maintain and the like. The device which clings to the outside of a human hand to detect joint movement is designed, and a unique connecting mode and ingenious joint measuring point layout are adopted, so that impedance and influence, on finger movement of an operator, of a detection mechanism are lowered or eliminated; when the operator uses the device, flexibility and lightness in movement of fingers can be maintained to greatest extent, and movement state of joints can be accurately detected, so that finger joints of a controlled slave hand and corresponding finger joints of the operator are enabled to act coordinately, and complex control on the slave hand with multiple degrees of freedom is enabled to be 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...
