Snail Car

March 23, 2004
Design a vehicle that will go the slowest.
Try to maximize the time from the wide start to the finish.
The time can be figured from the graph from data logging the light sensor readings.



1 to 5 gear ratio is faster than the 1 to 25 ratio.


Big wheels go faster.

Seeing how to gear up and then using the gears in the other order helps.

This is slow.

White areas are high sensor readings and dark are low.

Drag friction helps slow the vehicle.



Friction on the axles really slows the vehicle.

Davis Creek and VOB connect through Red Rover.

Next year we will be together in middle school.
