A servo driven pendulum gets a robot swinging attached to an anchor via a cable winch on any canvas. A 2-axis canvas is created which could scale to any size of canvas with the only expense of the cable while only one anchor needs to be attached to the canvas. Indoor (whiteboard) and Outdoor (building walls) use are possible. The robot will carry different sets of tools, options include air brushes (RGB for mixing colours), spray cans, crayons, markers, optical laser for cutting material, etc. Images uploaded to be printed will be compiled depending on the toolset in use.
