A long desire of mine has been to create an autonomous flying solution.

<ol> | |||
<li>Solution cannot touch the ground</li> | |||
<li>Retrieve a metal ring on the other side of a barrier</li> | |||
<li>Bring it back to its origin and drop it off</li> | |||

The autonomous rc helicopter from Stanford won the competition. Blimps were tried but they flew away etc... in the outdoor winds. | The autonomous rc helicopter from Stanford won the competition. Blimps were tried but they flew away etc... in the outdoor winds. | ||
