International Aerial Robotics Competition, Mission 6, 2011.

Today is August 7, just arrived from California in North Dakota. (And yes ND really is as flat as a frying pan.)
Very hungry and tired, will walk to the University campus later, I'll try to post pics and vids from here on out.

Need sleep...

Monday, August 8, 2011.
Check in begins...
Indoor flight issues, team unpacking, safety and registration today.

So far today...
Met most of the teams and staff, spent time with the Pima Community College team, two other groups are flying in today. Have pictures of an awesome arena! The Embry-Riddle AU team is in my hotel! They have decided on the quad-fan type machine and are not using there innovative maple leaf (mono-copter) design this time.
The competitors: Link2

I should be seeing the flight machines setup and working today, I'll get pictures of the course too, should be built by now. Ill postvideo and pics as soon as possible. Rumor has it that the organizing staff maybe using the ridgid foam covered with shiny foil, some teams wonder if there cameras, lidar or IR sensors could be useless...



Ok, todays pics:

The course! How diabolical to ask a flying robot to navigate this course, find a USB flash drive and escape.
All without any human involvement, from start to end! suprised



Wenesday, August 10, 2011.
Flight competition scheduled all day.

Have pics and vids, im composing, editing and writing stuff up now. Will post after sleep.

Thursday, August 11, 2011.
Formal dinner from 6-9PM, with scoring and placements announced tonight.
Dressed up ready to go!

Friday, August 12, 2011.
Analysis and sleep....

Saturday, August 13, 2011.
Traveling all day towards home.

More to come!

Cool competition! What team are you on, USC? Are all the teams using quad copters?

I'm trying to start my own CSU Chico flight team, but if I could'nt the USC team offered me a home.
No, not all are quad-rotors, some are balloon/blimps.

Ill post more pics later today.

How do the quads navigate? Is it all computer vision?

Some use the Micro$oft Kinnect which is disassembled and modded for object identification / collision oviodance, but almost all use the LiDAR device to actually navigate down the hallways.

Computer vision has been demonstrated under non-flight conditions, but so far no one used "full" computer vision except the Pima teams ballon. the Pima team's ballon used a line generating laser diode and a camera computing pythagorean theorem for a 90' triangle to see distance.

Thanks for posting, keep them coming. Can’t wait for the video!

LIDAR and laser painting is OK but to keep weight down has anyone tried to use ambient light (or a simple LED IR source)and synthesize a three line scanner out of a custom reading or video processing of a CCD output (ie: like to old EG&G Reticon line scans but with a single CCD for all three vectors). With a suitable beam splitter lens and custom ASIC in a small package. If not, although autonomous, are you allowed data transmissions back and forth? This could allow heavy duty processing off-board if needed.

Nice stuff. Is DARPA a sponsor?

Yes, the Pima Community College was the only team that used the system you describe, one of there own design. All other teams used lidar, and one used the Kinect.

Yes, off board processing and two-way communication is allowed, so long as the whole system is atonomous once started.

It apears not to be a sponsor as seen in the pic below.

"Yes, off board processing and two-way communication is allowed, so long as the whole system is atonomous once started. "

That opens a lot of possibility. A one or two cm^3 beamsplitter/CCD package with remote line vector processing could be very powerful for navigation, ranging and recognition....

that is what one of the teams is doing, the others are using "optical-flow" analysis.
