AI Technical Summary

Technical Problem

Existing technologies make it difficult to enable legged robots to move accurately to target locations in unfamiliar environments, especially when high-precision environmental maps are lacking.

Method used

A multi-signal vision-assisted method is adopted, which combines a camera and GPS with an attitude sensor to initialize the robot's posture. Then, the target position information is recorded through GPS positioning and environmental image acquisition, and the robot moves precisely based on a real-time environmental map.

Benefits of technology

This technology enables robots to move accurately to the target location and maintain the correct orientation in unfamiliar environments, either autonomously or manually, improving positioning accuracy and stability in the absence of GPS signals.

Abstract

The application relates to a quadruped robot path planning method and system under multi-signal visual assistance, wherein the quadruped robot path planning method under multi-signal visual assistance comprises the following steps: when it is detected that the head movement of the robot detected by the attitude sensor meets a preset track, initializing a camera and a GPS; in response to a first control signal, controlling the movement of the quadruped robot; in response to a second control signal, collecting the GPS positioning of the robot at a first position and collecting a first environment image; storing the GPS positioning, the environment image and the first movement direction when the second control signal is responded to as a first target position; and in response to a third control signal, moving to the vicinity of the first position based on the GPS positioning; moving to the first position based on the first environment image and the first movement direction when the second control signal is responded to, and moving towards the first movement direction. The application realizes the accurate movement of a robot to a destination in an unfamiliar environment.
