Its not checkpoint, its slovakpoint rather.

Nice work. I want to know, what sensors do you use to orient the robot? Ultrasonic or IR?

[@andrejladislavsmith]

IR

[@marcushdgaming1]

how did you map out the maze, and which algorithm did you use for solving the maze and returning back home

[@liptoveffect3073]

We stored each Tile separately and then applied BFS algorithm. It was simple and does the job very well.

[@andrewachraf4821]

What are the sensors you have used to make the wall follower ?

[@liptoveffect3073]

Distance sensors - "IR Lidar", Ultrasonic...

[@321timer6]

How did you program the Map, I mean that the robot knows where he was and where he have to go??

[@liptoveffect3073]

List of tiles and applied BFS

@@liptoveffect3073 Thank you, but how did you applied this in the arduinio code, can you show some links or explain it?

[@jorgedeleon6348]

Hi!! How does your robot detect that it is in a new tile?

[@liptoveffect3073]

Hello, it does not. It just simply goes 30 cm forward

[@levkozlov4059]

Sorry, but how do you check where you shoud put rescue pack? Which sensor do you use?

[@liptoveffect3073]

We use contactless temperature sensors for detecting heated victims and cameras for letters

[@levkozlov4059]

Liptov Effect Do you use arduino? And which camera?

[@liptoveffect3073]

Yes, and the camera is openmv.io

[@levkozlov4059]

Liptov Effect thank you, good luck!!!

[@vazoid4455]

Wich camera did you use to detect the letters on the wall?

[@andrejladislavsmith]

OpenMV

What sensor di you use to orient the robot? A gyro? Or a compass sensor?

[@andrejladislavsmith]

acc + gyro

Can you give me the code

[@liptoveffect3073]

Hello, we can ask your questions about the robot.

I will pay you for the bot construction and coding

Hello, the spirit of Robocup Competition is to learn a lot of new stuff and this can be achieved by building and programming robots.
