I initially threw together a super rough sketch for the light painting robot. It was going to be an arm with a light that could move up and down the length of the arm while the arm itself rotated around a central axis. This idea barely survived the lego prototype phase.

I only had access to a hammer and a butter knife to build the first version of the robot. This made it very difficult to get precise cuts, and the overall build was incredibly unstable. As you can see in the video, it falls apart almost immediately. I procured the rails from home depot, and the wood from scrap pieces I found on facebook marketplace. The motor carriage I built using lego pieces and tape.

I experimented with different LED brightnesses to determine what would create the best light painting effects. I took the RGB LED and waved it around in front of a camera with a long exposure setting to capture the light trails. As you can see in the photos, the initial results were too washed out, resulting in white lines rather than distinct colors. After adjusting the LED brightness I was able to achieve distinct colors in the light paintings. Once I had the brightness dialed in, I had the robot create a few test light paintings. These were made from me scribbling out a quick circle, so they aren't impressive, but they showed that the robot was capable of creating light paintings.
