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! 3 TM

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 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): § § • • ► 15 straights 1 connecting section 2 1/4 straights 2 1/3 straights § § 2 line changes 13 curves 1/60 2 curves 1/30 6 curves 2/30 The track is powered by the original power supply 14. 8 V, 2 x 350 m. A (Carrera ID: 26724) The track does not include shoulders or guardrails Slot Car Properties • The slot car Carrera Evolution Audi R 8 original chassis, body, guide blade, motor and tires must be used. • The traction magnets must be removed, no traction magnet is allowed. • The slot car can be equipped by additional electronics, but only inside the body. • The slot car weight is limited by a maximum of 125 g. • No remote control of the car is allowed. • Only one switch allowing to choose between two modes of operation is allowed on the slot car. 14 TM
