-UR5 Robot Arm
-Neopixel Ring – 24 LEDS
The most astounding thing about the robot arm is how accurate it is. It can move in specific paths down to the millimeter. I thought it would be interesting to utilize this to “capture” something by accurately recreating it. Without using a pen and paper to, I decided light painting would be an interesting way to recreate something using the robot arm. I chose the northern lights because as seemingly random as they are, every image has a trajectory. I thought it would be interesting to accurately recreate something as random as the northern lights.
- I used Openframeworks to do analysis on the various frames of the Aurora.
- I took the baseline that I extracted and used that as the path of the robot.
- Lit the Neopixel according to the gradient of the aurora (height of the Neopixel ring being proportional to the height of the aurora)
- Colored the Neopixel ring in an aurora gradient.
- Took long exposure photograph of the Neopixel ring, moving along the baseline.
