Abstract

Current material handling systems exhibit anisotropic behavior. That is, their two planar degrees of
freedom require different amounts of force input from the operator. Movement of these devices is
correspondingly difficult.

One of the three most prevalent material handling devices, the jib crane, is selected for research into
creating isotropic motion. A platform for this research is created with two intended future directions in
mind. The first direction creates isotropy by floating the boom over the load. The second direction
adds a powered trolley and is capable of providing power assist to actually accelerate the load.

The thesis walks the reader through the design of the platform. Selection of the jib crane is followed by
the design and selection of a servo motor and transmission capable of supporting both future directions.
A cable angle sensor and ultrasonic distance sensor provide the intelligence necessary to achieve
isotropy.
