2013 Big Island MATE ROV Competition

For the sixth year running I made the drive to Hilo to help in judging the Big Island Regional 2013 MATE Underwater ROV competition. Too much fun to miss!

As usual Keck provided much of the official staff. This is the fault of Keck software engineer Al Honey, the head official, who drafts the rest of us into being there! An engineer from Liquid Robotics and a couple folks from the observatories in Hilo rounded out the judging staff. Add teams from schools all over the island and mix with water to create an event.

The missions continue to increase in complexity. This year the task was a simulated undersea research platform. Various instruments were in need of upgrade or servicing. Opening a hatch on the “undersea instrument platform”, disconnecting power, removing an instrument, installing a new instrument, removing bio-fouling, a long list of tasks, each worth a few points in the final tally. Never-mind the instruments were made of PVC and the bio-fouling was actually pipe cleaners, it still was not easy!

Science Fair Season

School science fair season is here! As an engineer, it is wonderful to see school kids doing science and engineering tasks. I enjoy going to see what the students have come up with and giving a little of my time to support science and engineering education.

Science Fair
Students from Parker School participate in science fair
In the past two weeks I have served as a judge for two science fairs, Parker School and Kanu o ka ‘Āina. Parker is a private school in Waimea with a well deserved reputation for excellence. Kanu is a charter school with a heavy emphasis on Hawaiian culture. Both schools make a special effort with science fairs, expecting their students to participate and go on to the county and state wide competitions.

As usual, the projects are quite the mix. Some projects are simply the usual stuff, variations on the standard projects one can find posted to the internet, standard fodder for science fairs nationwide. Not that I totally disapprove of these common projects, students can gain valuable experience when performing any good experiment, even one done many times before. It is all in the execution.

One difference you really find here in Hawai’i, is a heavy emphasis on Hawaiian culture and special problems unique to the islands. This leads to unique experiments that address local issues. Propagation of native plants, alternative energy, permaculture, issues that have a direct connection with island life. Some student explore aspects of native Hawaiian technology. I was particularly impressed by experiments in traditional dye mordants examining the effectiveness and permanency of various mordants with tumeric dye and cotton cloth.

The results are likewise quite the mixture. Experiments that result in good success, to others that do not fair so well. Looking at a growth chart with all zeros in the data table I was forced to ask… “did the plants just not grow?” …”They all died.” Still, failures can be just as good learning experiences as success, sometimes better. I am always impressed by a student who admits failure and can explain what went wrong.

Some of the students I graded will go on to the regional competitions, I expect some will do quite well. Good luck!
