Abstract

The invention discloses a space robot teleoperation system based on three-dimensional gestures. The space robot teleoperation system comprises a gesture interaction sub-system, a predication simulation sub-system and an information management sub-system, wherein the gesture interaction sub-system is used for collecting and preprocessing human gesture information through gesture collecting equipment; the prediction simulation sub-system is connected with the gesture interaction sub-system, and is used for checking the legality of a teleoperation command sent from the gesture interaction sub-system, monitoring the current status data of a space robot, predicting the next status of the space robot through dynamical simulation and carrying out three-dimensional real-time display on the prediction status and current status of the space robot through a three-dimensional display module; the information management sub-system is connected with the prediction simulation sub-system, and uploading of the teleoperation command and downloading of monitoring status data are realized through communication between a ground station and the space robot. By using the system, the space robot can be accurately controlled to complete a series of tasks such as on-orbit maintenance, on-orbit module replacement and on-orbit fuel adding in real time.

Description

technical field [0001] The invention relates to space robot teleoperation technology, in particular to a space robot teleoperation system based on three-dimensional gestures. Background technique [0002] With the continuous development of human space activities, it is foreseeable that a large number of space production, space processing, space assembly, space maintenance and repair work will need to be carried out in the future. Due to the danger of the space environment and the high cost of astronaut life support, robots have played an increasingly important role in the aerospace field. However, due to the limitations of supporting technologies such as mechanism, control, sensing and artificial intelligence, the development of intelligent robots that can work autonomously in unknown or complex environments is an unattainable goal in the short term. Therefore, it is a more realistic choice to make full use of the existing technology and develop a telerobotics system that n...
