Problems solved by technology

Therefore, a system without force feedback has at least two disadvantages: first, it lacks a sense of reality; second, in order to avoid the appearance of unrealistic images such as holding a cup, some physical constraints have to be added to the visual calculation, which gives Computation in Visual Imagery Brings Trouble

Embodiment Construction

[0020] Such as figure 1 , figure 2 As shown, the mechanical structure of the skeleton type force feedback device mainly includes three components: the proportional electromagnet actuator, the wire rope-spring tube transmission mechanism and the skeleton mechanism installed on the hand. The electromagnet actuator includes a proportional electromagnet 1 and a bracket 2. The upper plane of the proportional electromagnet 1 is fixedly connected with the bottom plane of the box-type bracket 2; The amplifying mechanism includes a moving iron core 21, a bearing 22, a connecting rod 23, and a return spring 24, wherein the lower part of the side wall of the support 2 is located, and the bearing 22 is horizontally fixed on the two side walls, and the bearing 22 is fixedly connected with a connecting rod 23 orthogonally. , the bearing 22 is the rotating shaft of the connecting rod 23; counting from the axis line of the bearing 22, a moving iron core 21 is vertically set at one-third of ...

Abstract

A force sensation feedback device of framework type generates driving force with its size controllable by proportioned electromagnetic magnet through control current, then transmits the force to finger end by transmission mode of wire rope - spring tube and framework and finally acts feedback force on finger of operator based on DSP imbedded and closed control system.

Description

technical field [0001] The invention relates to the field of computer technology, and is a computer human-computer interaction interface, which is applied to the human-computer contact interaction interface in the virtual reality system and the force sense telepresence system in the field of robot teleoperation. Background technique [0002] In a virtual environment, one of the key factors that can make users feel "immersive" is whether the user can use his hands or other active parts of the body to operate virtual objects, and feel the real life of virtual objects while operating. force. The data glove can transmit the operator's flexible gestures and spatial orientation information to the virtual reality system in real time, so that it can generate images of the virtual hand approaching or moving away from the virtual object in real time, so that the operator can naturally convey his consciousness or operation mode sent to the interactive object. If the data glove does n...
