Problems solved by technology

[0003] The purpose of the present invention is to solve the disadvantages of the existing force feedback data gloves, such as high price, complex system, and difficult maintenance, and proposes a combination of an external angle sensor and a joint two-way active drive device, which is used to detect the movement information of human hand joints. At the same time, it also converts the feedback force sensory information into a force or torque that directly acts on the human hand, which greatly simplifies the complex force feedback data glove system

specific Embodiment approach 1

[0033] Specific implementation mode one: as figure 1 , figure 2 with image 3 As shown, the outer frame type two-way force feedback data glove includes a glove 101, a palm base 102, a thumb detection drive mechanism 103, an index finger detection drive mechanism 104, a middle finger detection drive mechanism 105, a ring finger detection drive mechanism 106, and a little finger detection drive mechanism. Mechanism 107 and metacarpophalangeal joint detection driving mechanism 108 . The outer frame type two-way force feedback data glove is suitable for most operators' hands of different sizes, so most of the components are preset with a plurality of installation holes arranged in a straight line, so that the operator can choose the appropriate one according to actual needs. Relevant components are installed in the position, so that the positions of each joint point of the data glove and each joint point of the operator's finger correspond to the best state. The glove 101 is m...

Abstract

The invention provides to an external-framework type bidirectional force feedback data glove and relates to a force feedback data glove which is used for detecting human figure moving status and is provided with a bidirectional active drive to feed back force borne by an auxiliary hand. The external-framework type bidirectional force feedback data glove aims to resolve the problems that an existing force feedback data glove is separated in measurement mechanism and feedback mechanism, complex in system, tumid in structure, difficult to maintain, unachievable in bidirectional drive, expensive in price and the like. According to the external-framework type bidirectional force feedback data glove, a joint detection mechanism is connected with a force feedback mechanism into a whole, a unique connecting mode and an ingenious joint measurement point layout are used, five fingers of a user are enabled to keep the maximum flexibility when the force feedback data glove is used, the moving status of each joints of the fingers can be detected accurately, the movement of each finger joint of the controlled auxiliary hand is enabled to be coordinated with the movement of a corresponding finger joint of an operator, the force bearing conditions of the auxiliary hand in a specific working environment can be fed back to the operator, and the immediacy sense of a virtual reality or a remote operation is enhanced.

Description

technical field [0001] The invention relates to a data glove which detects the movement state of human fingers and has the functions of bidirectional active driving and force feedback. 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 together to achieve specific functions, which requires the use of data gloves, and the data glove with force feedba...
