The first design, prior to the LEGO kit arriving.

First major LEGO version.

Current LEGO version.

The pan and tilt base went through several reversions until it reached its present form. In the current LEGO revision, the camera was flipped so that the cable did not catch on the base while rotating. The tilt motor was removed and was replaced by a pin that could be manually raised or lowered. The gear ratio was swapped from a ~4:1 to a 1.6:1 ratio. A special holder was built so that the base could be mounted on a tripod. A cable management bracket was placed in the back. An IMU holder was placed on the side of the hub and cables were routed out the top and through the cable management bracket. It is simple and efficiently meets our needs.
