Hi, we are a team of 10 students studying Mechanical- and Electrical Engineering at the Swiss Federal Institute of Technology (ETH) in Zürich or Industrial Design at Zurich University of the Arts.


Our goal is to build an electric wheelchair which is able to climb stairs. Moving on the ground is accomplished with a Segway-like system by balancing on the two main wheels. The stairs are climbed using two rubber tracks mounted on the bottom of the chair. Our system is designed to compete at the cybathlon championship 2016.

We are supported by the Autonomous Systems Lab and by our Sponsors.

Driving pleasure and agility on flat ground through two balancing wheels

Suitable for everyday use

Forward driving over obstacles with the aid of the support system


Park position with big footprint provided through the tracks and the support system


Because the Focus Projects have a very limited budget we are deeply grateful for the support from outside. With the help from many different companies we can do a good product. Those companies provide us capital, rabates, production and advice throughout the project. Are you interested in working with us? Contact us!
