  • Publication number: 20120185087
    Abstract: The present invention relates to a two-wheel type robot provided with two driving wheels. Supporting legs that closely contact or separate from a body have sharp ends, wherein the sharp ends are formed with curved surfaces for minimizing frictional forces. A cover for securing a battery mounting space is integrally formed in the supporting legs for a supporting leg to pass a raised protrusion smoothly and not be caught on the raised protrusion in the process of passing the raised protrusion, thereby enabling the two-wheel type throwing robot to move stably.

  • Patent number: 8162351
    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.

  • Patent number: 7688108
    Abstract: A data transition minimization method includes exclusive-NORing inputted nth image data (where n is a natural number) and (n?m)th image data (where m is a natural number smaller than n) expressing the same color as that of the nth image data to generate transition information data; generating inversion data indicative of inversion information by inverting all bits included in the transition information data and adding a unit bit having the logic value ‘1’ to the inverted transition information data when the number of unit bits having a logic value ‘1’ in the transition information data is larger than the number of unit bits having a logic value ‘0’ in the transition information data, and adding a unit bit having the logic value ‘0’ to the transition information data when the number of unit bits having the logic value ‘1’ in the transition information data is equal to or smaller than the number of unit bits having the logic value ‘0’ in the transition information data; exclusive-NORing the transition informati
