Includes bibliographical references.
In this thesis, we designed and implemented a machine to dispense and collect helmets for bike-share programs such as Boston's Hubway. Design of the machine was guided under several constraints including size and power for tight integration with existing bikeshare stations. The machine itself is divided into subsystems, including dispensing, reloading, and return components as well as software and electronics, power, and industrial design choices. The first prototype of the machine was implemented in December 2011, with refinement of the mechanisms occurring between January and May 2012.
