Robot Brings Concrete Form to Light Painting

Usually, the technique of light painting involves creative freehand designed created from a moving point of light. These designed are captured using a camera with a long exposure time. Usually, the subject becomes unrecognizable in the final product as a result of the imprecision of the process.

 

But Jeff Crossman has decided to use robot technology in order to bring precision and concrete identity to this art form. Using this method, Crossman creates stunning light versions of 3-D pictures of people. 

 

The source images for Jeff's light paintings are captures from an Xbox Kinect camera, and the data is then processed with 3-D software in order to generate a point cloud composed of as many as 5,000 dots of light. A robot arm is then equipped with a flashing RGB (red/green/blue) LED light that can generate any color on the spectrum. Over the course of about 25 minutes, the robot arm then recreates that cloud.

 

 

It's a tedious process, but the results are astounding. And the precision and stability of the robot arm means that Jeff could eventually create light animations - a feat that would have been impossible using just human hands.
