Perfect Spiral, Every Time

[Carmine] let us know about his team’s Automated Football Launcher. Their goal was to combine a football launcher with motion tracking, to allow a player to practice running and catching with the perfect throw. Unfortunately, and we’re not quite sure when, they ended up changing out the Jugs machine for an air cannon, which resulted in the use of foam footballs and the loss of throwing factors such as spiral. Somewhat defeating the purpose but we’ll let it slide; only because we know its going to be shooting potatoes eventually.

The project comes together by using two cameras giving distance and color tracking, combined with a rotating platform (and the best use of garden hose ever), an accurate set-top for their launcher. As seen in the video after the jump, it works out quite nicely. Continue reading “Perfect Spiral, Every Time” →

Football Hero

For Kasabian’s new single Underdog, they decided to do something original. After dreaming up a Guitar Hero style controller powered by soccer football players, they set out to make it happen. Using 5 wall mounted pressure sensors connected to a microcontroller, they hooked up the rig to a computer running Frets on Fire (an open source Guitar Hero clone) with a custom version of their single. After an afternoon of practice, the team was able to 5 star the song, and while this isnt the only or most complex Guitar Hero hack, we would love to have this in our house.

Video after the break.

Nanobot Nanosoccer

May 31, 2008 by Juan Aguilar 2 Comments

Medgadget recently published a post about a soccer competition for nanobots at RoboCup. The nanobots compete on a field that measures 1500 by 2500 micrometers with goals on the long sides jutting 500 micrometers out. Like normal soccer athletes, the nanobot teams attempt to push the ball – in this case, a silicon dioxide disc with a 50 micrometer diameter – into the goal. The nanobot competitors are monitored by an optical microscope and are remotely controlled by magnetic signals sent across the arena.

The National Institute of Standards and Technology (NIST) and RoboCup have already held two nanobot competitions in the last year. Nanobots made by different teams from various universities compete to test various abilities that will be critical for their practical applications in medicine, manufacturing, and other industries.

Though it is referred to as nanosoccer, the competition is actually a triathlon. The bots must sprint to the goal with the ball in one event, then maneuver the ball around stationary “defenders” and into the goal in the next event, and finally score as many goals as possible within 3 minutes. NIST and RoboCup hope to show the practical potential of nanobots with this competition and have a little fun in the process.
