Smart Car Race

Project:
Smart Car Race

Introduction
In this report we discuss the SMART CAR, which was designed to participate in the line follower competition. The main proposal in this competition is toproduce an intelligent racing car, based on the microprocessor HC12 which is responsible for controlling the car through the interpretation of the signals received from sensors, the intelligent racingcar will recognize the track automatically to run on the specifically designed racing track and must be traveled in the shortest possible time without the lowest possible errors runs out of the trackfor more than two times and after running for two laps, racing car doesn´t stop within the racing track in 3 meters after the starting line.

1. - Description of Major Concepts and Specific TechnicalImplementation Schemes for Design and Production of Car Models

Angles of the vehicle

Drop angle: The angle between the wheels with the ground. Its function is to improve grip in the corners tocompensate for the deformation of the tire lateral force to do it.
Caster angle: The angle that we look at the vehicle side, the angle of the knuckle, it is the tube with the vertical direction.Departure angle: Looking at the vehicle in front is the angle between the pivots to the vertical direction.
Beam angle: It is known as convergence and divergence. If we look at a car from above, is theangle between the wheels with the central straight line of the vehicle. At first glance it seems logical that the 4 wheels perfectly parallel is the best solution. In line, 4-wheel parallel produce aslittle friction as possible.
Ackerman angle: The Ackerman geometry suggests that when a vehicle rounds a curve, the inner wheel rotates around a smaller circle than the outside wheel.

2. -Description of Mechanical Design of Car Model.

The mechanical design of the smart car has developed under the rules of competition, it consists in:

1. Suspension: It holds the centric force...
