started in
left corner; made R, R, R, R, 180, L turns so far; green wall signals end
![](images/maze-crawler2.jpg)
IR sensors everywhere!

hold 'er back!
Sebastian Pfaff and Adrian Wong: Bluetooth Beamer (BMW)
Bluetooth car controlled by accelerometer (tilt) hand paddle with LCD
![](images/bt-car.jpg)
car and paddle
![](images/bt-car-demo.jpg)
tilt paddle forward/back for drive/reverse and turn like steering wheel for turns
Jesse Cohen and Eric Iwinski: Knockin' on Heaven's Door
Smart door that opened to secret knock if RF-ID present; funny sound effects;
Winner of Most Awesomest
![](images/heavens-door.jpg)
ominous green eye
![](images/heavens-door2.jpg)
RF coil upper right; piezo sensor middle; speakers for sound clips (wrong, wrong, wrong, wrong!)
![](images/heavens-door-demo.jpg)
mating coil hidden up sleeve: tricked audience
Slater McArdle and Rhiannon Williams: Groovebot
Dance Robot modified to boogie to ambient music, depending on tones/beats
![](images/dance-bot.jpg)
Travolta?

Mad Moves
Kirill Kouprine and Christina Valen: ARFF: Automated RF Finder
Car that could locate RF transmitter and steer toward source
![](images/RF-finder.jpg)
antenna on car pivots 360 and finds direction to source
Thomas Morales and Molly Whitnack: Smart Safe
Solid safe with keypad entry/electronic open; dialed actual phone if foul play suspected;
Co-winner of Most Impressive
![](images/smart-safe.jpg)
keypad, LCD
![](images/smart-safe2.jpg)
Gold in there! Dialed cell phones depending on which kind of offense (police/owner)
![](images/smart-safe-demo.jpg)
A stick-up! Excellent.
Vicente Espinoza and Adrian Cusigch Botamino: Block Mopper Hopper
Rolling platform located junk on floor, maneuvered and grabbed to put in basket
![](images/block-mopper.jpg)
claw would grab block and raise up to drop on back; IR sensors on clear horse-shoe localized
Jonathan Trisnadi: Turn Your Voice Up (or Down)
Playback of recorded sound pitched up or down according to potentiometer value while recording
![](images/modulator.jpg)
Simple hardware; complexity in computer/software end
Becca Bladorn and Danny Chi: Linearity is a Rarity: taping
the future of transport?
Car followed tape-line track on floor by optical sensing
![](images/tape-track.jpg)
LEDs illuminated path
![](images/tape-track2.jpg)
you calling me a liar?
![](images/tape-track-demo.jpg)
car had good "track" record (ha-ha) for staying on tape line
