While [Ted] was poking around the ‘net, he came across a neat little product called a camera dolly. These are used to add an artistic flair to filming. They are similar to a camera slider but can roll around on the floor or a table and do not need to follow a track. [Ted] wanted a camera dolly but the cost of a professional product seemed too expensive for what he’d actually be getting, so he set off to make his own.
[Ted] first designed the dolly in a CAD software and printed out templates for the parts. Those templates were then transferred to plywood and cut out with a jig saw. Three inline skate wheels support the frame and allow the unit to roll around. Mounted in the center of the frame is a pan and tilt camera mount.
The extraordinary part of the build is that the angle of each wheel can be adjusted independently. This allows the dolly to do anything from rolling in a straight line to gradually traveling around a curve or even just spinning the camera in place. Each wheel mount has degree indications so that they can be adjusted very precisely as well as be returned to a previously recorded position.
