For a visually impaired person landmarks play central role in his environment recognition. We set landmarks in the environment by RFIDs. We want to identify, trace and localizing them. As visually impairedness badly interfere with the detection of changes in the environment, we target localization of active RFID tags which are deployed in the room and subject to spontaneous move. We analyze experimental...
A tactile sensor is developed with the aim of covering a robot's entire structure, while reducing wiring requirement and ensuring high-speed response. The sensor detects the center point of load distribution on 2-dimensional surfaces as well as the overall load. There are only 4 signal wires from the sensor. The sensor response time is nearly constant (within 1ms) regardless of the number of detection...
