The main idea used in this project is the usage of blade-less fans in place of conventional propellers. The main structural modification depends on the degrees of freedom available and/or are possible to create for a blade-less fan.

This project is solving the ZERO GEE Bee – Your Friendly Neighborhood Drone challenge.


Conditions assumed to be present in the International space station -Zero gravity -Air pressure similar to that on earth

Challenges for a quad-copter to function in zero gravity -The ability to generate thrust in all directions Reason-There is no downward force of gravity -Broken pieces must not be created due to collisions Reason-It can be harmful to astronauts

Solutions Broken pieces causing floating debris -This is solved by using of blade-less fans instead of conventional propellers.

Thrust in all direction -This is can be achieved by one motor and one circle with bidirectional flow as depicted in the resource images (drawn by me as simulator was not working)

Different structural configurations possible are explained in the video link
