Abstract
A system for automated movement of a reference point along a three dimensional path stores a three dimensional path including a plurality of spaced apart points. A velocity vector of the reference point and a look ahead vector extending from the reference point define a plane of travel. A directional vector of the reference point is determined along the plane of travel, and a command vector directs movement of the reference point at least in part based upon the directional vector. The velocity vector and the look ahead vector may be used to determine the directional vector. A method is also provided.
