SMALL MOBILE ROBOT WITH BUILT-IN AUXILIARY WHEEL FOR OVERCOMING TOPOGRAPHY
First Claim
1. A mobile robot that communicates while in motion and transmits various types of information at an intended position in real time, the mobile robot comprising:
- a main body including two main wheels at both sides thereof;
a servomotor installed on the main body and including a rotation shaft that rotates forward and backward;
an auxiliary wheel connected to the rotation shaft of the servomotor through a linkage part; and
a one-way rotation member attached to the auxiliary wheel to allow the auxiliary wheel to rotate only in a forward direction and prevent the auxiliary wheel from rotating in a reverse direction, and wherein the auxiliary wheel is retracted in the main body in a normal state, and is lowered out to contact a ground when meeting a stepped topography such that the auxiliary wheel functions as a support in the reverse direction and functions as a rotation auxiliary wheel in the forward direction to go over a stepped part.

Abstract
Provided is a small mobile robot which moves back and forth and left and right while keeping its posture by two main wheels. The small mobile robot includes built-in auxiliary wheels to overcome topographical elevation differences. The auxiliary wheels of the small mobile robot are attached to a servomotor. The servomotor is driven by remote control, and the auxiliary wheel can be moved to the position required for operation. When the robot is in a normal state, the auxiliary wheels are retracted in the robot. When the robot meets a stepped topography, the auxiliary wheels are lowered out to contact a ground to support the main wheels going over the stepped topography. The small mobile robot includes a sensor for sensing obstacles and a control module to make a detour around obstacles while moving to a target point.
