2010
Dimensions: 27"W x 37"L x 16"H
Weight: 120 lbs
Concept:
Our team decided that the ability to go over the bump
would be important in the game. Although going under the
tunnel would be difficult (due to the careful alignment
involved), we decided to build the robot so that it
could drive under the tunnel if we needed to, both as a
way to force us to keep the center of gravity low as
well as to give us the option of going under the tunnel
the one time it may be useful. To maintain
maneuverability as well as go over the bump easily, we
chose an eight-wheel-drive design.
A surgical tubing powered kicker, reloaded by a
pneumatic cylinder, was simple to design and implement,
and has less points for failure. It allows us to kick
the ball into the goals from almost anywhere on the
field.
Finally, because the robot would be very short relative
to its weight, we were able to strengthen parts of the
robot where, in previous years, we would not have the
weight to do so. The result is an extremely robust
design.
Features:
-Custom two-speed shift on the fly transmission (8 and 16 feet per second)
-Extremely robust
-Very low center of gravity; virtually impossible to tip
by itself
-Ball retention device to possess balls when the robot
lines up for a shot
-Kicker capable of scoring from all three zones
-Goes over the bump and under the tunnel

2009
Dimensions: 27"W x 36"L x 58"H
Weight: 110 lbs
Concept:
Early on in the design process, our team recognized two general design
approaches to the 2009 Challenge: A "dumper" that could unload a large number
of balls quickly, but only in one direction, or a "turreted shooter" capable
of scoring at various angles, but would be slower and
potentially less accurate.
Our final design was a hybrid of the two; we combined the throughput of
the dumper with the flexibility of the turret. The end result was a robot that
could score within a 180-degree arc from the front of the robot, and do
this at 7 balls/second.
Features:
-Custom single-speed transmission
-Four-wheel tank drive
-Modular design
-Large hopper
-Pickup balls from the ground
-Shoots up to 7 balls/sec.
-Automatic camera tracking enabled
-Able to score autonomously
