PROJECT TITLE :
.Net-Structure Proximity Sensor: High-Speed and Free-Form Sensor With Analog Computing Circuit
This paper proposes a proximity sensing system, which has benefits of wide sensing space and rapid response. For the fast and safe behavior of robots, high-speed detection of nearby and noncontact objects is vital as a result of of shorter time-to-contact. Here, we have a tendency to propose.Net-structure proximity sensor (NSPS), that covers giant sensing area and fulfills 1-ms response time. NSPS is an array of infrared reflective proximity sensor parts integrated by a resistor network circuitry. Executing analog computation on the electrical circuitry, the sensing system outputs some of meaningful signals, from the reaction distribution of all the elements. The signals mean the center position and approximate distance to the object. This sensor needs only six external wires no matter the quantity of detecting parts. In this paper, we 1st show that various sizes of NSPS are easily configured by only using commonplace electronic parts. Next, we tend to prototype NSPS with twenty five components in 5 × 5 matrix, and verify the output characteristics by experiments. At last, we have a tendency to discuss the provision of NSPS for robot hand systems and human-machine interface systems.
