For the 23rd year in a row, several university teams have come together to do the impossible with autonomous aerial vehicles. This was the first year of “Mission 7” which tasked collegiate teams to build a system that used unmanned air vehicles to avoid moving obstacles and direct free running iRobot Create robots, based on the Roomba floor sweeping models, across a goal line and prevent them from leaving the 20 meter by 20 meter field. A complete description of the contest and the rules can be found at: http://www.aerialroboticscompetition.org/. This is an international competition. The teams that competed in Georgia were from Canada and the U.S. while almost simultaneously there was a separate venue running the competition in China with teams from China, India, Iran, Hong Kong, Singapore, and Spain. None of the teams successfully completed the mission this year, as expected. The missions created by Rob Michelson are very challenging. Rob’s intent is to have a contest that pushes technology to its extreme limit just beyond the current capability of most of the competition teams.
The contest has always focused on autonomous systems. It is not a contest of the eye hand coordination of the operators but their ability to make a system that can perform the various tasks without human intervention. Of course, there are “operators standing by” with kill mechanisms to bring down the flying vehicles immediately if there is a problem and they have been needed from time to time.
This year the vehicles were required to navigate a 20 meter by 20 meter field in a building where GPS assistance would not be available. The vehicles had to avoid moving obstacles that were as high as 2 meters and interact with free running autonomous robots (iRobot’s Create robots—similar to the Roomba vacuum cleaners). The goal is to herd robots across a green boundary line and prevent the robots from exiting out of the other three sides.
This year one team at the U.S. venue and two teams at the Chinese venue flew completely autonomous. Those three were the only teams that could accrue points in the competition. Autonomy is a fundamental requirement. Even so, the points are meaningless except for bragging rights. No team successfully interacted or changed the trajectory of the free-running robots which means next year everyone is at the same level. The team that successfully herds the most robots across the green boundary while demonstrating intelligent navigation and obstacle avoidance will win the first phase of Mission 7 and be rewarded with a prize of $30,000. Once that happens, the top teams will be invited to compete in the second phase where teams will be pitted against each other in an elimination contest thus demonstrating the ability for autonomous systems to sense and avoid competing robots.
Each year I look forward to spending time with Rob Michelson and his wife Denise, along with their two sons, who I’ve watched grow up from elementary school to college graduates, along with the other judges. I’m especially looking forward to seeing the advances these young people make as they attempt the impossible for the second time.

Do we have “buffer zones” in our lives? Decisions are coming out of the Supreme Court about the constitutionality of various laws but something can be constitutional and still be a bad idea. The ruling is based on the complaints of street counselors who felt that they have a First Amendment constitutional right to personally talk with and give literature to patients going into a women’s health facility that provides abortion services. While I can agree with the Supreme Court decision on rational grounds, I have to question whether or not it is right that these “street counselors” should be trying to give advice to someone that clearly didn’t ask for it. I hate it when I get unsolicited advice from people, even friends. Is it just me? In fact, I’ve become quite rude about it. If someone calls me on my phone at home offering to sell me anything, I hang up the phone. When people come to my door with a petition, or selling me something, I point to the “No Soliciting” sign and close the door. However, when a young lady is walking into a clinic after making what could be the most difficult decision of her life, how does she “hang up the phone” or “close the door“?

animals.
the box was about 6″ by 9″ and 5″ tall with a lid and a bottom made out of plywood. There was a lot of work that went into the kitting of these boxes. Holes were predrilled and countersunk. All the hardware was available but there was a lot left to do by the campers. There were several hammers and three electric drills for the campers to use to drive the screws that held the main frame of the box together and attaching the two hinges. But the best part of the memory box activity was that once the boxes were complete and placed in their proper order, they revealed a special picture with meaning for science based campers…Ta Dah!
ribe Camp Quest AZ 2014 but I’m glad to have been a part of it and hope to be a part of it again next year. Camp Quest is now a feature of the Secular Community of Arizona and we owe a great deal of thanks to the volunteers that made it happen for the second time! Thank you John, Eugene, Chuwan, Jennifer, and Holly for all the hard work and making it happen again in Arizona!
