Retired engineer and inventor Bob Gray has a progressive motor neuron disease similar to Lou Gehrig’s disease or ALS. Bob predicted his own walking and then arm strength would become increasingly compromised over time.
He has designed, made and overseen the making of machines that will help him maintain his independence for as long as possible.
