"Industrial Robot Demo Maker Person. We salute you, and your latest idea involving robots, slot cars, and Mario. And there's more, of course, because it's Video Friday."

"wearable computing and prevention-through-design to develop a practical sensing and alarm system that can tell when a worker's blood oxygen level is cratering and prevent carbon monoxide poisoning. The result was a standard construction hard-hat modified to include a non-invasive blood-oxygen monitor."

"The Solara is intended to lift a payload to 20,000 meters and then keep it there for five years, running entirely on solar power. It functions a bit like a satellite, except substantially cheaper and much more versatile. And, you can get it back when you're done."

"Learn how forces and simple machines can work together to create The Compound Machine!"

"No matter what anyone tells you, EVERY paper airplane needs fine-tuning to achieve its best performance.  There are several things you should keep in mind while making adjustments to your planes. "

"Download any of the free paper airplane designs below and get flying!   Just print out the template onto standard 8.5" X 11" printer paper.  The fold and cut lines are clearly printed right onto the template, and each paper airplane design has easy-to-follow instructions.  Make sure to read the printing tips at the bottom of this page.  Also see the Flying Tips page for information about how to get the best performance out of your models.  "

"human power, delivered to the craft's four rotors through the bicycle pedals he steadily pumps throughout his flight. It's that fragile machine, built by Reichert's Canadian team, which has now won a long-coveted international prize that lay unclaimed for years. The AHS Igor I. Sikorsky Human Powered Helicopter Competition was established in 1980 for the first successful controlled flight of a human powered helicopter that could reach a height of three metres while hovering for at least one minute in a 10-square-meter area."

"anniversary of Neil Armstrong's walk on the moon, and apparently it is celebrated as Moon Day (that was news to me). Here are some previously-posted "The Best…" lists that are related to the moon"

"To celebrate Moon Day, catch up on the latest in lunar exploration and space travel. The ideas worth sharing here are the first steps in the next giant leap for mankind."

"Students construct balloon-powered racing cars using a foam tray and drinking straws. They then test the cars along a measured track on the floor. At the conclusion of the activity, students submit a detailed report on their racer design and how it performed in the trials."

"Rule of Three -- a three-member team means each team has three relationships being negotiated. I made that change in my classroom and found that teams of three became units able to function at a higher level more quickly, and they really needed each member present to make it work. Three students gave them enough variety of experience and ideas to sharpen their creativity and enable outside-the-box thinking. Also, it was easier for me to devise tasks and deliverables that gave each member something meaningful to contribute."

"coaxial rotors, uses a pair of helicopter rotors mounted one above the other to produce both lift and thrust. Sikorsky's high speed technology demonstrator the X2 uses this design as well as many Russian helicopters. To neutralize the torque, the rotors spin in opposite directions creating equal and opposite torques that cancel each other and eliminate the need for a tail rotor. Yaw control is achieved by increasing the collective pitch of one rotor and decreasing the collective pitch on the other. "

"paper and a stapler would be all you need to create a life-size structure big enough to hold a bevy of children? Our dome was, at turns, a fort, a gingerbread house, a cave, and a camping tent. And after the fun, it was easily turned back into plain old recyclable newspaper."

"You can be a Moon explorer too. Practice by building your own Moon habitat. Pretend you are an astronaut working with your team mates on the Moon to build your new home. Materials you will need to build one Moon habitat: 148 sheets of newspaper (use a paper with large pages-tabloid size is too small-and use the full square spread)"
