This is the final build before the semi-finals begin. Trying to get into the semis are the Trash Can Heroes and the Sewer Rats. Today, they must create a garbage eating machine. They will each navigate garbage in one half of an oval track. There are 3 heats each longer than the last and each with heavier garbage than the last. The final heat will also have parked cars to clean around. The team that has the heaviest load of garbage after the 3 heats is the winner.
The aptly named Sewer Rats are going to try and suck as much as possible at this contest. They plan on building a giant vacuum on the back of a truck. The most crucial piece of their machine will be the fan that provides the suction. It will have to be powerful enough to suck up debris and also be rugged enough to handle heavy garbage too. If the fan breaks during any of the clean-up times, it could be a lop-sided victory for the other team...especially if it breaks during the first heat.
The Trash Can Heroes are building a "traditional"
brush sweeper. A series of flaps, some bristles and some "squeegees" will
flick the garbage forward and into a hopper mounted on the back of the
truck. By driving backwards they will have better maneuverability but the
spinning garbage-flicker might just throw the garbage into the air and
very little into the hopper.
