Robots lead the blinds (pas de s, c'est invariable)

An intelligent white cane that blind people can use to find their way has been developped (un seul p) by researchers in Michigan.
The cane is a robot that will gently lead them around any obstacle in their path.
Many industrial robots are strong and capable, but almost blind, says Johan Borestein (nom propre, ortho au pifomètre) at the University of Michigan.
The intelligent cane we have created for the blinds is the opposite.
The prototype guide cane looks like an ??upgraded?? upright vacuum cleaner.
In its base is an ??question crescent- shaped array of ultra sound?? sonic sensors that scans the area ahead.
A built-in computer interprets the data from the sensors, calculates the best ??root?? route every fifty milli-seconds, and steers the device accordingly.
All a blind person has to do is follow.
The guide cane ??wise?? for weighs four kilograms.
Borestein says that unlike a guide dog, it requires no maintenance other than recharging its batteries.

The majority of blinds and visually impaired Americans are over sixty and few of them can care for a dog or provide enough activity to keep it healthy.
At the moment, the device cannot sense over *** overhanging obstacles, and can only operate on smooth surfaces.
It also ??count output?? can't cope with stairs.
Ultimately, we would like to incorporate a global positionning satellite receiver, so the that users can could choose a destination, and the guide cane will *** would steer them along the best course.
