Chinese inventor creates The Walking Chair

A Chinese man, 65-year-old Beijing resident Li Rongbiao , used his pension money and sold his house to invent a power wheelchair that can go up stairs and also works on flat ground. It sells for about $1500.

However, the building of the chair took a bit of time since Rongbiao first had to handle all the basics. Thus, he taught himself computer designing for 6 months before spending the rest of the year constructing his dream chair.
