The semiautomatic small mobile robot that picks up the tiny object dropped instead of the person is described. The use of this robot assumes the case where the user of the wheelchair drops the thing to the narrow space. The robot is basically controlled by the person. And, when the person doesn't control easily, the robot moves by the automatic operation. The robot is controlled by using personal computer and PIC (Peripheral Interface Controller) and recognizes the target object using two cameras. As a result, the burden of the user can be decreased. This paper reports the machine structure and the system configuration of the small mobile robot developing.
