The left chart shows the adjusted detection distance compared to the actual sensing distance for white, gray, and black objects using a BGS sensor with a visible red light source. At an adjusted distance of 700mm, the measured sensing distance varies by ~150mm depending on what color is present. The right chart shows the same for a BGS sensor with an infrared source. This results in a sensing distance variation by color that can be just one third that of visible red versions, at the same distance.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicleís parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but thatís just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
