Making a car for blind drivers

Using robotics, laser rangefinders, GPS and smart feedback tools, Dennis Hong is building a car for drivers who are blind. It's not a "self-driving" car, he's careful to note, but a car in which a non-sighted driver can determine speed, proximity and route — and drive independently.

Dennis Hong is the founder and director of RoMeLa — a Virginia Tech robotics lab that has pioneered several breakthroughs in robot design and engineering.
