Robots that print on walls

The wall-printing robot that’s garnered the most attention recently is Scribit, a word that means “he/she writes” in Latin. Did you know it wasn’t the only one? Read on to find out about it and its analogs.


Scribit lets you print and erase as many times as needed. People use it to print a different image on their walls as often as daily. It can print, erase, and reprint content thanks to a special patented technology an infinite number of times, letting users select a new wall decor as frequently as they want.

How does this robot work? Basically, it uses wheels to scale up vertical surfaces of every type. Glass, whiteboards, and standard plaster are the recommended surfaces if you want the highest quality drawings.

It takes only a few minutes to install the robot with its inbuilt engines. All you need is a power plug and two nails. What is more, its special patented technology makes it possible to transform practically any surface into a screen – a wall of magic where images, feeds, messages, feelings, and thoughts are projected.

Scribit is always online, meaning that you can source, download, or upload any content from the Internet. A financial services company can upload stock market updates in its lobby, a cafe can post the day’s menu, and a lover of art can project Sunflowers or their own art onto their living room wall. Scribit’s interactive software enables real-time replication of any kind of data, including images, notes, messages, and graphics.

According to Carlo Ratti, who created Scribit, people spend too many of their wakeful hours in front of screens and there is no need to add more. The robot is his alternative.

Robot Muralist

This robot is hailed by its creators as the device that creates impactful public art. It can print images to any flat surface in any size. The robot can transform cities, homes, communities, and public areas through the vision of artists.

Robot Muralist is a leap toward greater creativity, engaging societies and activating vibrant neighborhoods across the globe. People’s environment is related to their productivity, creativity, and physical and mental health. Art in our surroundings helps us feel safer, inspires positive thoughts, and helps us live more happily.

NTU Robot

Researchers at Nanyang Technological University (NTU) in Singapore have managed to overcome spatial constraints by creating a moving robot that 3D prints concrete. A project to get it to print on walls is in the works. For now, this impressive robot features a 6-axis robotic manipulator based on an interconnected mobile platform equipped with a single printing nozzle that uses sensors for localization.
