Italian architect Carlo Ratti has created an internet-connected writing robot that is able to draw and erase images on any surface. The small Scribit robot allows users to personalise their walls with digital artworks. It will be unveiled at this year's Milan design week, taking place from 16 to 25 April 2018. Requiring just two nails and a power plug, the device can be installed in less than five minutes. It then uses inbuilt engines to move, draw, erase and re-draw new content a limitless amount of times.
