Introduction
► University student competition based on slot car racing
► The Goals are:
• To develop the best control algorithm that will drive the slot car on an unknown track
without student interfacing.
• To achieve the best time for 10+10 laps without dropping out of the track.
► The Objective is:
• Map the track shape during the first lap and use it to achieve a maximum speed in the
following laps.
► How
can the car map the track? Accelerometer measures centrifugal forces.
► With the support provided by Freescale and Carrera,
• Populate the provided PCB
• Build it into the provided slot car
• Create the slot car intelligence (development tools provided)
• Test it on the provided track
it's easy to go for it!
Racers need to have acumen and accuracy.
Forethought, creativity and a bit of skillfulness is needed here!

Competition Rules – Main Race
►
Racing Rules
•
All contestants place their cars into pits before the race.
•
Each contestant races separately against time.
•
The contestant called on takes his car from the pit and place it anywhere on the track.
•
The time measurement is started on the first pass through the time counter and stopped after 10 laps.
•
If the car drops out of the track the contestant can be put it back, to a position clearly before the drop-out point. Only one
person of a team can do this.
•
After the ride, the contestant places the car back to the pit and keeps away from pits.
•
There are two race rounds and the sum of both race times will determine the final result.
•
The slot car is placed to the right line of the track for the first round and to the left line for the 2 nd round.
•
The starting order is random for the first round and a reverse order to the intermediate results is used for the second
round.
►
Track Properties
•
The race track is unknown to the contestants until the race.
•
The track can consist only from the following set of Carrera Evolution pieces (all or a subset):
