In this paper, we propose a design method of resistance for Net Structure Proximity Sensor (NSPS). Generally, vision sensors and tactile sensors are used for the external world measurement. A vision sensor has the problem of occlusion and a tactile sensor cannot detect until coming in contact. Therefore, we have developed NSPS that detects the intermediate area of vision and tactile area. NSPS can detect within 1ms the center position of the approaching object and the distance to the object without contact. This sensor is composed of resistor networks connected by phototransistor. The performance of NSPS is determined by the resistance in the networks. However, there was no practical design method of the resisters because of the network circuit. Accordingly, we describe a method for designing easily arbitrary dynamic range and faster measurement speed and confirm the validity of the proposed method.
