AI Technical Summary

Technical Problem

Existing surveying robots have difficulty crossing obstacles in complex geographical environments, especially in areas such as mud and sand dunes where they are difficult to free themselves after getting stuck. They also have difficulty flexibly crossing obstacles to complete surveying work in fire zones, which poses safety and efficiency problems.

Method used

An unmanned surveying robot was designed, equipped with an obstacle-crossing walking mechanism and a forward turning mechanism, including an obstacle-crossing lifting arm and an obstacle-crossing wheel. The obstacle-crossing wheel is driven to rotate by a rotary motor, which raises the frame and allows it to cross obstacles. At the same time, it is equipped with an angle adjustment motor for flexible turning, which improves the robot's mobility in complex environments.

Benefits of technology

It enables the robotic vehicle to smoothly cross obstacles in complex terrain, improves its ability to escape from mud, sand piles and other environments, enhances its flexibility and surveying efficiency in fire areas, and reduces the difficulty of operation and safety risks.

Abstract

The utility model discloses an unmanned surveying and mapping robot which comprises a robot trolley, the robot trolley comprises a frame, and a plurality of distance measuring probe structures are installed on the top of the frame. A plurality of forward turning mechanisms are mounted on the frame; a forward turning mechanism; the device further comprises a plurality of obstacle crossing walking mechanisms installed on the vehicle frame, each obstacle crossing walking mechanism comprises an obstacle crossing lifting arm rotationally connected to the side wall of the vehicle frame, and a rotating motor for driving the obstacle crossing lifting arm to rotate is installed on the obstacle crossing lifting arm. The obstacle-crossing lifting arm comprises a lifting arm part rotationally connected to the frame, an obstacle-crossing arm part is integrally formed on the lifting arm part, an obstacle-crossing rotating wheel is rotationally connected to the obstacle-crossing arm part, and the obstacle-crossing walking mechanism further comprises a motor for driving the obstacle-crossing rotating wheel to rotate. By means of the structure, the technical problem that in the working process of the robot trolley, the robot trolley can cross obstacles, especially when the driving rotating wheels of the trolley are caught in mud and sand piles and the bottom of the trolley frame scratches the obstacles, the trolley cannot normally walk is solved.
