This is the section of web site where I present hand operated walking vehicles for handicapped persons.
The first tests were providing on the beach in Gdynia in 2001 year. My be, it was the first hand operated walking vehicle in the World.

The possibility of building the family of walking vehicles gives me a very careful analysis of elephant walking and experiece during construction of block lifting machines. This analyse I described in my book "A Different Story about the Wheel".
