A Walker with Artificial Intelligence
From: Medical Design Technology - 07/27/2016

Mexican scientists have thought up a way to implant artificial intelligence
(AI) into a walker to provide those who need one added mobility.

The prototype is built on a normal walker, but in each of the rear wheels, a
movement is generated by an engine similar to that of two electric bikes. The
handles are replaced by a micro system sensor that will measure the strength
used by a person to make sure they are in constant contact with the walker.

The walker is connected to a small computer and a bicycle battery that allows
for an Internet connection, through which the information of the handle
sensors and wheels is controlled. A person’s gait patterns can be measured,
and if there is an abnormal situation, the walker tries to help. If there's a
serious situation, like a person falls from the walker, the machine sends an
alert signal that can send the location out for medical assistance.
