Robot DJ?
How
often have you heard someone at a party say, "Oh, change the
music, nobody is dancing to this song!" Well, that problem is
now solved with Lego Mindstorm user Roligheds invention, the PARTY
OPTIMIZER. Stop dancing, and the music will change. Wave your hands
to the camera, and it will play the track you want to hear! The Party
Optimizer was built using Lego Mindstorms Vision Command and can play
9 CDs in order or shuffle them. Other features include changing the
music when there is no movement on the dance floor, change music
according to hand motions and take a photo of the dance floor every
few minutes. On the Lego Mindstorms Site you will find many musical
lego inventions including The Opera Bot, The dancing ChaChaBot, and
the violin playing Music Bot, and if you ever have some spare
time(like months!) you too can make yourself a personal dj lego bot
with the cool kits listed on the Mindstorms site.
The Party
Optimizer can:
1) play all 9
CDs in order or "shuffle" them.
2) change music
if there is no movement on the dance floor.
3) change music
according to your hand motions.
4) take a photo
of the dance floor every few minutes.
All functions
are controlled by the LEGO Cam and the Vision Command software.
If no movement
is detected on the dance floor, the Party Optimizer presses the
"Next" button on the CD player. If there is still no one
dancing, the Party Optimizer presses "Next" again. If there
is still no movement on the dance floor, the Party Optimizer will
choose the next CD (or one chosen at random).
Meanwhile, if
the partygoers are dancing, Vision Command snaps photographs and
stores them on the computer for later viewing. (Maybe you'll discover
some interesting things that happened on the dance floor while you
were looking the other way!)
At any time, the
Party Optimizer can be operated by waving to the camera in certain
patterns. Depending on the pattern you choose, you can give the robot
these commands:
- Next track
- Previous track
- Change CD
- Play CD
- Stop CD
With a bit of
practice this is actually quite easy!
When all the CDs
have been played (or skipped!), the program will wait for you to put
in 9 new CDs and start dancing again!
