Scribit is a drawing robot that can turn your walls into a work of art. The little bot has already raised more than $2m (£1.6m) in a crowdfunding campaign. Scribit uses four erasable markers to draw images up to a 6.5 ft x 6.5 ft on your wall. Images are uploaded from a user’s phone to the robot and automatically starts drawing. It’s held to the wall with just two nails and guide wires that move it along the wall.
