With an extremely simple mechanism, the HyTAQ has made a vast improvement to standard quadrotor design. Instead of only being able to fly, which can be cumbersome in windy areas, or when needing to get around certain obstacles, this one can now land and roll. The video clearly shows how well they made this happen.
The frame looks extremely light weight judging by the speed and maneuverability they show in the video. I wouldn’t be surprised to see this interesting concept showing up in more quadrotors in the near future.
