Propeller based human powered swimming device
Currently the only human powered swimming device widely sold on the market are swim flippers. However, flippers are not efficient for the human body, and there is a potential to increase the speed while swimming with a device. This thesis is the planning, design, construction, and prototyping of a …

Design of a human powered maize mill
The process of milling corn into flour in many rural communities of East Africa has remained a traditional mortar and pestle process for centuries. Milling machines have failed in these communities largely due to poor performance, as well as high cost, and as a result the incredibly labor intensive …

Designing the Human-Powered Helicopter: A New Perspective
<p>The concept of human-powered vertical flight was studied in great depth. Through the manipulation of preexisting theory and analytical methods, a collection of design tools was created to expediently conceptualize and then analyze virtually any rotor. The tools were then arranged as part of a …

Design, prototyping and preliminary testing of an elastic-powered climbing exoskeleton
Human powered elastic mechanisms can be used to reduce work requirements of muscles, by storing and releasing energy to more evenly distribute work load. An exoskeleton was designed to delay human fatigue during rock climbing. This exoskeleton stores energy in the less intensive motion, extension …
