Automatic tracking and navigation system of intelligent aid type walking robots

Abstract

The invention relates to an automatic tracking and navigation system of intelligent aid type walking robots in the technical field of robots, comprising a sensor signal acquisition processing module, a watchdog intelligent body pre-diagnosis module, a network information processing module and a motion control module. The sensor signal acquisition processing module acquires sensor signals as photoelectric conversion and analog-to-digital conversion processing; signals after conversion are used as information input of signal processing module in the watchdog intelligent body pre-diagnosis module, one path of the prediction and estimation results is sent to the network information processing module, and the other path is sent to the motion control module; the network information processing module is sent to a server by reading sign performance state information of object to be aided, and the server is in charge of storing these information; therefore, corresponding strategy is provided for doctor or expert decision-making system. The invention prevents the damages caused in walking aid process by estimating and predicting the sign performance of object to be aided, and intelligent monitoring and tracking are realized by networks.

Description

technical field [0001] The invention relates to a tracking and navigation system in the technical field of robots, in particular to an autonomous tracking and navigation system of an intelligent walking-assisting robot. Background technique [0002] In recent years, with the development of computer, sensor and network technology, it has become possible for robots to enter the home. The research focus of research institutions and manufacturers has also shifted from fixed robotic arms and manipulators in structured environments to autonomous mobile intelligent robots in non-structural unknown environments. The traditional modeling of the space environment of the manipulator based on the factory environment and the collision avoidance method during the movement have been unable to meet the new tasks faced by autonomous mobile robots, such as intelligent assistance and walking assistance for special groups of people, so recently for The research on service robots tends to focus...

[0004] It was also found in the search that Aaron Morris of Carnegie Mellon University published A Robotic Walker in Robotics and Automation, 2003.Proceedings.IEEE International Conference. (2003 IEEE Robotics and Automation International Conference, Vol.1, No 25-30, 2003) That Provides Guidance (a walking-assisting robot that provides navigation function), this article describes a kind of intelligent assisting walking-assisting robot, which is equipped with embedded industrial computer, motion control card, laser rangefinder, sonar , microphone, touch screen and visual sensor, this system is powerful, but it is only suitable for indoor environment, and cannot realize intelligent tracking and health tracking in outdoor environment
