## Getting started
The main branch contains the following files:
>
localization.py: localization algorithm
>
driving.py: detection of section type, calculation of odometry, calculation driven distance in section
>
grafic.py: graphical output
>
race_management.py: main program
>
Lokalisierung_LEGO (folder), main.py: programming of the robot LEGO EV3
*
localization.py: localization algorithm
*
driving.py: detection of section type, calculation of odometry, calculation driven distance in section
*
grafic.py: graphical output
*
race_management.py: main program
*
Lokalisierung_LEGO (folder), main.py: programming of the robot LEGO EV3
## Name
localization of a vehicle on a race track
## Description
The following adjustments might be necessary, before the algorithm is executable:
>
change ip-address in main.py
>
entering the route in localization.py (get_set_of_section_*())
*
change ip-address in main.py
*
entering the route in localization.py (get_set_of_section_
*
())
Important notes regarding the robot:
The sensors / motors are connected to the following ports of the robot:
>
Motor: OUTPUT A & OUTPUT B
>
ColorSensor: INPUT 4
>
GyroSensor: INPUT 1
*
The sensors / motors are connected to the following ports of the robot:
*
Motor: OUTPUT A & OUTPUT B
*
ColorSensor: INPUT 4
*
GyroSensor: INPUT 1
The following measured values are stored and must be adjusted if necessary (in main.py):
>
wheel circumference (radumfang)
>
wheel spacing (d)
*

Notes on constant values (in race_management.py):
>
CHAR_RECIVING: number of chars in one UDP-message
*
Notes on constant values (in race_management.py):
*
CHAR_RECIVING: number of chars in one UDP-message
This value should only be changed if the sent string changes.
>
THRESHOLD_LEFT, THRESHOLD_RIGHT: value to detect a left or right turn
*
THRESHOLD_LEFT, THRESHOLD_RIGHT: value to detect a left or right turn
This value can be changed to possibly improve the algorithm.
>
BLOCK_SIZE_DA: number of iterations to analyse the section type
*
BLOCK_SIZE_DA: number of iterations to analyse the section type
This value can be changed to possibly improve the algorithm.
>
S = 0: value for a straight part of the track
>
R = 1: value for a right turn
>
L = 2: value for a left turn
*
S = 0: value for a straight part of the track
*
R = 1: value for a right turn
*
L = 2: value for a left turn
This values should not be changed in order to maintain the algorithm.
