Having a disability is definitely difficult, and these people are facing various problems. Moving in wheelchair through some cities can be a nightmare, and one of the biggest concerns for mobility impaired person is certainly – overcoming stairs. Well, some smart people have designed a brilliant new wheelchair that will make life a whole lot easier for wheelchair users.
It is called Scalevo, and it is a project by seven mechanical engineering students from the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland who in early 2013 wanted to create a robot that could climb stairs. But, it turned out that this is a much better solution. It is electrically powered and balances on two wheels while driving on even ground. To be able to climb stairs it uses a set of tracks which can be lowered dynamically to keep the user level at all times!
