# Traveling robot

## Abstract

A traveling robot comprises: a lower housing; a frame assembly positioned inside the lower housing; a traveling unit position at the lower part of the frame assembly; a tray frame coupled to the upper part of the lower housing so as to extend upwardly; a load cell coupled to the tray frame; a moving bracket coupled to the upper part of the load cell; a tray holder coupled to the moving bracket and protruding through a fastening hole of the tray frame; and a tray module seated on the tray holder. By having the load cell, the traveling robot is capable of detecting whether an object placed on a tray is present or falling, toppling over, etc. and thus is capable of traveling in a stable manner.
