     There are many challenges facing people with disability in their daily life. To support them, many instruments are developed. In this research, a robot arm system was designed, developed and controlled by use of an EOG (ElectroOculography) signal generated by the eye movement. To get the gaze position through EOG, an estimation method of gaze positions was proposed. The method is to use vector and maximum value of EOG. The error range between real gaze and estimated gaze motions and positions was from -4° to +10°. To improve the controllability of the system, a switch was introduced. It works when operator blinks. The function of the switch is to change the method of gaze motion and position estimation. One of them is estimation in two dimensions, the other is estimation in four directions (up, down, right and left). To prove the efficiency of the switch function, two experiments were done. Operators got the tip of the robot arm coincided with targets by using this system. In the experiments, one was the system with the switch. The other was the system without switch. The finished time of the experiment with switch was half, compared with the experiment without the switch. The results proved the efficiency of the switch.
