AI Technical Summary

⚠Technical Problem

Mobile robots face challenges in navigating uneven surfaces and obstacles while minimizing impact and maintaining stability, especially when crossing steps, which limits their widespread adoption due to high manufacturing costs and the need for advanced navigation and obstacle detection capabilities.

⚗Method used

A driving robot design featuring a front caster with a V-shaped rocker bracket and two caster wheels, where the first wheel remains in contact with the ground and the second wheel is smaller, allowing it to overcome steps by rotating within its radius, while the elastic part and teeth on the second wheel provide stability and propulsion, minimizing motor capacity and power consumption.

🎯Benefits of technology

The design enhances the robot's ability to navigate over steps and maintain stability, reducing power consumption and extending operating time, thus addressing the challenges of uneven terrain and obstacle detection.

Abstract

Provided is a driving robot comprising: a body on which a battery and a control module are mounted; a main wheel which is located below the body and moves the body by power received from a motor; and a front caster located in front of the main wheel and fastened to the body to be rotatable about a vertical caster axis. The front caster includes: a caster frame rotatably coupled to the body about the caster axis; a rocker bracket comprising a first arm and a second arm, which are rotatably fastened to the caster frame about a horizontal rocker shaft and extend in different directions from the rocker shaft; a first caster wheel fastened to the first arm of the rocker bracket; and a second caster wheel fastened to the second arm of the rocker bracket and smaller in size than the first caster wheel.
