Previous notice method of three dimensional robotic arm motion for suppressing threat to humans

This paper describes previous notice method of three-dimensional robotic arm motion for suppressing threat to human using a device in which LED markers are arranged like a coordinate frame. Firstly, a previous notice method for the three dimensional position of the endpoint of the arm is shown. Secondly, relationship between the dimensional number of the motion and the feeling of the human is investigated using the device of the previous notice. Finally, the effectiveness of the notice device is evaluated for the three dimensional motion of the arm. This device is effective for all motions and, especially, is much effective for the motion of the upper level from the eyes of human.
