This topic inspired us a lot and the idea of facilitating the life of disable people encouraged us to participate in this challenge.
We are designing a carousel automatic shelf which takes advantage of the rotational movement to make the structure lower and help people in wheelchairs to reach heights that they couldn't in a normal shelf.
To control and move it easily without efforts, we are using a voice recognition system and an additional touch-screen which allow to select the shelf you want to reach.
