Notes from the Edge
A Californian company, 5D RoboticsTM, proposes we mark locations with transmitters broadcasting in ultra-wideband (PulseON® UWB) frequencies. PulseON® UWB signals are low power, which makes for short range – about 200m – but if you have enough beacons, that shouldn’t be a problem, says Philip Mann, 5DTM VP for sales. “The beacons measure the distance between themselves by simple ranging; then a vehicle can navigate by triangulation.” The company is testing the waters carefully. They’ve adapted their system for use with some of the slowest vehicles around: wheelchairs. 5DTM is developing, in cooperation with San Francisco startup Whill, a new type of wheelchair: the Model A.
