DrawBot is a wall robot created by teacher Edwin Dertien and his student Janwillem te Voortwis. The robot moves up and down on bicycle chain pulleys. When in the exact correct spot, it uses one of eight spray cans to spray out some color.
It can create a 3 ‘ x 4’ work of art in about two hours.
Here it is shown making it’s own version of the Mona Lisa.
Once a spray paint can is empty it needs to be replaced, often with a different color. This helps create a pop art effect.
