Mi Lapse is in the process of engineering an open-source software and hardware motion control system for time-lapse photographers and videographers.
The video here was captured whilst testing the first (v1) of three prototype dolly designs. The prototype used here weighs about 15lbs (6.8Kg) total and is 72" (184cm) long with about 60" (150cm) of travel x 8" (20cm) wide
This test was conducted with 'slim' (node 122) the simple pearl script interface. If your curious to see a source file, 1mm-ish per move macro accuracy test, and the prototype itself, then click here.
