Prototype Capacitive Sensor-Based Robot Safety System

摘要

Research was reported concerning the protection of workers from robots by the use of intelligent sensors. A capacitive proximity sensor was studied specifically as a component of a safety sensor system. Both the computer signal processing and human spectral filtering systems were improved in the research over earlier technology. System components described included antenna design, sensor electronics (oscillator, capacitive bridge, signal detection circuitry, and power supplies), and control electronics (computer signal processing, human spectral filter electronics, automatic nulling circuitry, robot control, and sensor interfaces/multiple sensor integration).
