SMALL MOBILE ROBOT WITH BUILT-IN AUXILIARY WHEEL FOR OVERCOMING TOPOGRAPHY

摘要

The present invention is a small mobile robot which moves back and forth and left and right while keeping posture by two wheels, and the small mobile robot system can overcome topographical elevation differences through two built-in auxiliary wheels. The auxiliary wheels placed in the small mobile robot of the present invention are attached to a servomotor to drive the servomotor by remote control, and can move to the position required for operation. The auxiliary wheels are hidden inside the robot when the robot is in normal motion and are lowered to contact the surface when the robot meets changes in elevation, then supports main wheels, when the main wheels come across high elevations. In addition, the small mobile robot of the present invention comprises a sensor for sensing obstacles and a control module to make a detour around obstacles during the journey to the destination. The small mobile robot has functions for grasping the position thereof through wireless communication between robots during the movement and transmitting environmental information through a camera. The small mobile robot of the present invention is capable of moving smoothly even on the topography with an elevation difference through a slight change of the posture including the auxiliary wheels. Therefore, there can be an excellent economical advantage, due to a simple structure.
