The points of those geometric shapes line up completely thanks to the delta robot arm controlling the light source. The source is a easy LED that can be changed on as well as off as it moves. A video camera is set up in a dark space to keep the shutter open while the arm moves. We’re presuming that all of the light for the stationary objects in this picture comes from the LED as well.
[Sick Sad] developed the delta bot for just for this purpose. inspect out the video below to see, as well as possibly much more significantly hear, the thing in motion. Seriously, the whine of the stepper motors is quite remarkable on this one.
The delta idea utilizes a central head on three arms angled down from above. If the LED is likewise directed down it won’t illuminate the hardware as well as that’s why it doesn’t show up in the image. We’ve seen similar accuracy when utilizing this style of device for 3D printing. however if you don’t want to develop a challenging device you can try this out with a easy string plotter.
