* Upgrade on NASA sphere project to satisfy Zero GEE BEE challenge requirements (Zero gravity movement and 2 kg transportation). * Modifying of CO2 tank to provide space inside the sphere to be available to carry the payload. * Mechanism to recognize the payload, its priority, grab and drop as well as the destination.

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

  • Project main targets: 1- Zero gravity flying. A- Installing gyroscope for reading feed back while navigating with the payload. 2- Transportation of 2 kg. A- Modifying the CO2 liquid tank from cylindrical shape to pipe grid to provide empty space close to the sphere center of mass and keep the sphere homogeneous. B- Giving other options for recharging CO2 like external co-tank that supplies the portable inside liquid grid in the sphere. C- Color code on the payload case to determine destination and priority achieved by installing a camera at the sphere. D- Grab and drop mechanism depends on zero gravity.
