With the right parameters, we can make them *just* clip their rotors and keep flying as if nothing happened!<br /><br /><object width="640" height="360"><param name="movie" value="http://www.youtube.com/v/XJFGuyBNClo&hl=en_US&fs=1&rel=0&color1=0x2b405b&color2=0x6b8ab6"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/XJFGuyBNClo&hl=en_US&fs=1&rel=0&color1=0x2b405b&color2=0x6b8ab6" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="640" height="360"></embed></object>vectra14http://www.blogger.com/profile/16719432789673921190noreply@blogger.com2tag:blogger.com,1999:blog-6337431693219504713.post-57280067599065559072009-10-20T22:26:00.001+02:002009-10-20T22:29:33.406+02:00The Distributed Flight ArrayA short video which introduces the Distributed Flight Array which is being developed at ETH Zurich. This multi-propeller platform consists of autonomous single-propeller modules that are able to drive, dock with their peers, and fly in a coordinated fashion. These modules are organized as distributed computational units with minimal sensory input. This is a complex system that is rich in dynamics with much room to explore various strategies of distributed estimation and control. Several demonstrations in docking, driving, and flight have proven its feasibility. The work shown here was completed by the 2008/9 AYIM class (<a href="http://www.andyetitmoves.org/">http://www.andyetitmoves.org/</a>).

The balancing mechanisms are independent of the cube’s structure, and can be arranged into other “balancing” shapes, such as a wedge or a tetrahedron.<br /><br />For more information about the Balancing Cube and how it works visit the Balancing Cube research page.Halliehttp://www.blogger.com/profile/07026761838439699453noreply@blogger.com0tag:blogger.com,1999:blog-6337431693219504713.post-65556549660200786132009-08-19T16:51:00.004+02:002009-08-20T13:27:49.940+02:00Distributed Flight Array<img src="http://www.idsc.ethz.ch/Research_DAndrea/DFA.gif"><br /><span style="font-weight:bold;">We’ve all heard the expression: “The whole is greater than the sum of its parts.” Alone, these vehicles can drive about on the ground, but it is not until they come together that they are able to fly.</span><br /><br />The individual vehicles of the Distributed Flight Array have fixed propellers that can lift them into the air, but the resulting flight is erratic and uncontrolled.
