The Carnivorous Syndrome in 3D contains unprecedented 3D macro time lapse, shot by jasper, a robot made of Lego (R) bricks.
Normally, when one makes a 3D movie, two cameras are used--one to capture a left view, and another to capture the right view. However, if one wants to do macro 3D video, the cameras would need to be just 6mm (.25 inch) wide! I don't know whether such cameras exist, but if they do, I can't afford them. My solution was to build a robotic system that could move and operate a single digital still camera.
The juxtaposition module holds my Nikon Coolpix 4500 digital still camera. (This is an outstanding camera for macro work, now obsolete.) The juxtaposition module slides the camera back and forth between two positions that are just 6 mm apart. By taking a picture at each position, the robot simulates two tiny cameras. In other words, the robot captures the view from the left, slides the camera over, and then captures the right view. Each left/right pair is converted (later) into a single 3D image.

The cable release module allows the robot to actually take pictures. Inside the boxy Lego (R) structure is the Nikon MC-EU1. This is essentially a remote control for the camera. The cable release module holds this remote control, and a "finger" mechanically depresses the button, causing the camera to take a picture. The yellow device pictured is the RCX 1.0--a Lego microprocessor that coordinates all of jasper's functions and movements. [Click photo for instructions/MLCAD file.]
The rotation module is simply a bonus feature of jasper's. I wanted to see plants rotating while they grew, in 3D. In order to achieve this effect, the rotation module had to be capable of turning in discrete, .1 degree steps. This would allow the robot to take 1800 photographs over the course of a week or two, with the rotation occurring after each left/right pair. The end result would be 30 seconds of macro 3D timelapse video of a plant growing while rotating 90 degrees. [Click photo for instructions/MLCAD file.]
