Driverless Wheelchair = Independence

A day doesn't seem to go by when an article associated with "driverless" automobiles does not show up on your smartphone.  But what about those people who must depend on a wheelchair to get around, either temporarily or because of a permanent disability?

Motorizing a wheelchair is one thing, but adding a "driverless" capability is quite another. Researchers at MIT and the University of Singapore have developed a prototype wheelchair equipped with "driverless" features. Enter where you want to go, and it takes you there. It can detect unexpected obstacles, even someone walking in front of the wheelchair, and it can be summoned electronically using a standard GPS system. It is always a great source of pride in our profession when engineers tackle problems for those who have special needs. - Dr. Tom
