• Resumen

  • Drones could soon be criss-crossing cities delivering pizza, cleaning windows and inspecting infrastructure, thanks to a sensor that will help them autonomously avoid hazards while flying at speed. InVisage Technologies of Menlo Park CA has built a low-cost sensor called the SML20 that can rapidly detect obstacles up to 20 meters away. It exploits a technique called structured light, using laser pulses to project dots that are distorted by any object they strike. The reflected light allows the sensor to infer the location and distance of obstacles ahead
