The first attempt at Mission 8 of the IARC (International Aerial Robotics Competition) finished on August 1st in Atlanta Georgia. No team completed the mission, as expected, but three of the teams did qualify and had an opportunity to demonstrate their capability in the arena. By far and away, the Norway Team (Norwegian University of Science and Technology) with 5 flying attempts was the best prepared but Olin (Franklin W. Olin College of Engineering) and St. Olaf (St. Olaf College) each made 4 flight attempts. Other teams present were Missouri University of Science and Technology, Pennsylvania State University, PES University (from Bangalore, India), University of Michigan, University of Pennsylvania, and University of Texas at Austin. Teams travelling to the competition face many challenges. For example, the PES University Team’s vehicle was destroyed going through customs from India. The Georgia heat melted one team’s vehicles and they had to scramble to replace their propeller shrouds.
This contest has been held once a year for 28 years. The goal has always been to stretch the technology and it was created to be “hard.” It was/is/and always will be a competition based on autonomous vehicles. This year was the first year that the autonomous vehicles could be directed by a human operator through voice or gesture commands. Also, this is the first year that the mission was hindered by active sentry drones. There were four of them and their mission was to prevent the human in the arena from completing the mission. The rules explain in detail what is required and there is also a promotional video that dramatizes the task.
The next opportunity for college teams to meet the Mission 8 challenge will be at the Asia/Pacific Venue on August 24-25 in Kunming, China. Thirteen teams from China and 3 from India are slated to attend. The past two missions were completed at the Asia/Pacific Venue. It is possible but unlikely to have one of the Chinese teams complete the mission and collect the prize money. That would bring up Mission 9 and severely disappoint the creator of the competition. He wants the challenge to be tough enough to take a couple of years to accomplish. On the Past Missions page of the IARC Website one can see that Professor Michelson got his wish on every mission except for Mission 5.
Hello readers! Are you as frustrated as I am? It seems frustration is a way of life now that we’re under the current administration.
Coming off a natural high after spending a week at Camp Quest Arizona. Spiritually, I’m doing great. Physically, not so much. Every year recovery takes a wee bit longer. I missed a 4th of July party and opted to spend time with Nancy in front of the TV. We enjoyed a dinner of hot dogs, pork and beans, and potato salad. I could hear the fireworks, but the Lazy Boy was so comfortable…After a bit, I had to get up and walk. I like to walk four miles every day, and this time of year it’s best to walk after dark. I usually start at 9 P.M. and it takes a bit less than 90 minutes. This time, I took my Panasonic Camera. Normally, I only have my phone camera, but the last couple of days my headlamp was illuminating Wolf spiders that were carrying their babies on their back. I really needed the camera that has an optical zoom so I could hopefully capture momma spider and her babies. I’ve included one of the best pictures, but it really doesn’t do it justice. When wearing a headset, the Wolf spider eyes reflect very brightly. The momma spiders have a few dozen extra eyes and the effect is awesome when I’m wearing a headset. I’ve been trying to capture the image on the iPhone camera, but the effect was disappointing. Also, the momma spider would jump into her hole while I was setting up the shot.
The Camp Quest AZ mythical creature is Muggy—a bipedal humanoid wild creature thought to be a native of the Mogollon Rim. Every Camp Quest has its own mythical creature. I believe when Ed Kagin first started Camp Quest in 1996 in Boone County Kentucky for the children of secular families he played a game with an invisible unicorn in his garage. It was a challenge aimed at showing that a negative could not be proven. Back then, there was only one location for Camp Quest. Now, there are 14. Camp Quest Arizona is one of them.


The other “maker” elective was Rockets. Lauren taught her group how to build and launch rocket made from old soda bottles. This was the first year for this program and the campers that selected it had a great time building and launching their rockets.
It seems like all I write about in this blog, when I bother writing, is about Camp Quest. It’s not like that’s all I do but it is the highlight of my summer. At the time of this writing I’m about two weeks from taking the trip to the higher elevations of Arizona and the Piney woods of Prescott National Forest. While I’m there, the phone connection will be spotty. I’ll have to climb up to a ridge to get enough “bars” on my ATT phone to download podcasts and call my wife. That’s not a complaint; that’s a feature! I suppose the 3-minute cold water shower is a feature too.
common materials such as Popsicle sticks, tongue depressors, fishing sinkers, rubber bands, and plywood circles. We’ll also be using hot glue so the building should go quickly.
The two models to the left normally decorate my home office. Both are capable of hurling metal balls about 30 yards, but you’ll notice that the Mangonel on the left in the picture is sturdier in construction. It uses twisted nylon rope to store the energy. There is very beefy stop in the front of the throwing arm to stop its forward motion and loose the payload. There is a lot of potential energy left in the system once the missile flies. On the other hand, all the potential energy in the Trebuchet is expended and transferred to the missile. Therefore, the device can be built a bit lighter.

Camp Quest Arizona 2019 will be the end of June, but preparations have already begun. It’s a very busy week and proper preparations allow me to and the campers to get the most out of the experience. For the last three years, I’ve been building a simple set of shelves to take with me to camp. They consist of ½” PVC pipes and fitting along with repurposed political sign material—coroplast. Pictured are the three sets from the previous years. As you can see, they are full of stuff. My workshop always remains in a state of “organized chaos.” The hoarder quantity of raw materials contained there are sorted and labelled so that I have to spend less time looking for that all important widget that would be perfect for my most recent doo-dad. I’m sorry for all the technical jargon so let me briefly explain…my most recent “doo-dad” might be a Halloween prop or a cleaver way to ignite the fire at the beginning of the annual Winter Solstice celebration. In any case, now that the stuff is all sorted and labelled it doesn’t make sense to undo that. Therefore, I must build another set of shelves for this year’s camp. I’m running out of wall space however. So, what to do? This year I’m going to build a 10 shelf (taller) unit and transfer the containers from one of the shorter units to the bottom of the taller one. I only need 25 or so containers and the taller unit will hold 50. If I do this properly, I’ll pack away the disassembled smaller unit so that it won’t be used and full of
Here is the new 10-shelf framework.


Camp Quest AZ 2018 was the last week of June. There were 46 campers this year. The youngest was 8, the oldest 17. This was the 6th year for the camp and my 5th year as a volunteer program counselor. Program counselors are charged with providing the activities such as fishing, archery, survival skills, etc. There are also cabin counselors that are charged with the campers from a specific cabin. The campers are divided into their cabins by age and gender. Older campers assist the volunteers though a program called the Leadership Track. These LTs spend time at camp developing and running activities such as team games and the “Carnival”—an exceptional effort which includes music, games, face painting, balloons, and prizes. This year, one of last year’s LTs came back and did an excellent job as a volunteer camp counselor. Knowing that gave me a good feeling about the future of Camp Quest AZ.
The FrogBot was designed to be built in 45 minutes and involved the use of only a hot glue gun. The Line Tracker Car was from a kit which took about 4 hours to build. The campers used soldering irons and small hand tools
