ChalkBot - Digital Manufacture Concept


ChalkBot is a CNC chalk plotting tool that aims to improve the way we interact with our cities and communities by: promoting the adaptability of our public spaces; and establishing a sub-community through interaction with technology. 

ChalkBot is a new concept in digital manufacture and part of an exploration to discover how robots can become a part of our modern society. Initially developed as a tool to aid event planning, the overlay of different software enables a wide variety of professional and amateur applications such as pavement advertising, temporary construction planning, permanent road markings or installation art.





ChalkBot takes a digital drawing and recreates it in a physical space. The user creates or downloads a vector drawing of an event plan and positions it over a satellite image of the space. ChalkBot then replicates this drawing onto the ground of the physical space.

The current prototype is an amalgamation of existing systems and technologies. Stepper motors and omni directional wheels allow fluid movement over rugged ground, while GPS and a digital compass provide accurate movement. Compressed air and a spray nozzle plots the drawing on the ground with a custom paint solution which I designed to act like chalk, and wash away after a day.





ChalkBot is currently funded for its 4th iteration as a collaboration with a physics and arts student at Carnegie Mellon.
