Event 1: The Snowplow
In this event, teams designed, built, and programmed a robot to plow
flakes off a driveway.
At the start, the robot had to be placed against the side rail fully in
a garage. The robot had 60 seconds to find the driveway and remove as many
of 90 flakes of snow from the driveway as possible. Each robot had three
“runs”. The first run had no obstacles in the driveway, the
second run had one obstacle (a "car") in the way, and the third
run had two obstacles. After each run, the number of snowflakes removed
from the driveway was counted. The goal was to remove as many flakes as
Event 2: Roller ‘Bot Derby
event, teams built and programmed a 'bot to go head-to-head against
another 'bot in roller derby, 'bot style.
The rules of the event were as follows:
- This was a
double-elimination tournament. Teams were seeded based on the
results of the Snowplow event.
- All 'bots had to
complete a physical to ensure the light sensor and target worked and
that the target was placed in an accessible area at the top of the
- Robots started at
the start/finish line of the roller derby track facing opposite directions.
- The first 'bot to
complete one lap in the proper direction and cross the finish line
without being disqualified won.
- A 'bot was
disqualified if (1) the light sensor detected black, (2) the 'bot's
target was hit, (3) it fell off the side, (4) it blocked its target
too long (more than a second), (5) the target or light sensor fell
off, or (6) it wasn’t making progress for 15 seconds.
- If both 'bots were
disqualified, the bot that was farthest at the time of
disqualification won. If they were the same distance, the one there
the fastest won.
- 'Bots must be no
wider than 1/2 the track at the straightaway.
- A 'bot could
interfere with the other 'bot.
A light sensor was placed anywhere on the bottom of the 'bot. If the
sensor detected black, the 'bot stopped and played a tune of defeat. A
target that uses a touch sensor was placed on top of the 'bot. The target
couldn’t be blocked for more than one second out of a two second
interval. The target could move. All targets must be built like the model
target shown in class. If the target was hit, setting off the touch
sensor, then the 'bot stopped and played a tune of defeat.
