The suitcase comprises of an inner spherical storage unit that sits inside an outer spherical shell. Between the two components there are a number of motor / roller assemblies fixed to the inner compartment. The motor / roller assemblies exert a force on the inside of the outer shell which then propels the whole suitcase in any given direction. The process is similar to a hamster running inside of an exercise ball. The motor / roller assemblies are mounted such that the inner compartment is fixed centrally within the outer shell. To allow articles of clothing etc. to be placed inside the suitcase, both the inner and outer components feature a removable lid. Once the suitcase is loaded the lid is replaced to complete the spherical body.

This figure shows the inner and outer shells lined up with hatches removed. Once the hatches are put back the unit is self-contained and ready to propel itself about in any direction.
This invention was initially conceived as a means for disabled persons to possess the freedom to move about easily and independently, even when transporting bulky loads. The user would wear a transponder so that the suitcase could sense its owner’s location. The suitcase would then use its in built motors to automatically follow behind the user at a set distance.
Since obtaining the patent on this invention it has largely sat on the shelf. The next step would be to find a backer to commission a working prototype and continue the development of the design.
