Certainly a work closer to the perfection that I have seen, congratulations to the team, and I would like you to answer me, do you use how many sensors for gaap identification and what is your logic? I'm sorry, my English, I'm Brazilian.
Hi very good job, your robot is fantastic, only one answer... there is a light or color sensor in the front of the robot for see the ball or an other sensor? thanks very much
Feib Since the walls in the room are white and the corner for the balls is black we can differentiate between them by using a light sensor at the front.
ADREN00 good idea, we use two touch sensor in the forward-right and in the forward-left (sorry for my english but im italian) but for the ball what do you use? thanks for the question
We realized the balls tend to roll to the outside of the room so we decided to drive at the outside of the room without knowing if there are some balls or not. For the balls in the middle of the room we use two Sharp infrared sensors which we can connect to the NXT by using a transistor circuit. So basically the robot doesn´t detect most of the balls and the path for the robot is always the same.

We used the 3 light sensors from line following to identify the gap. There is a gap, when all 3 sensors where on white for a specific amount of time
how did you make it avoid the obstacles?
OLÁ, EU GOSTARIA MUITO DE SABER QUAL O NOME DO SENSORES QUE VOCES USAM PARA INDENTIFICAR A COR VERDE!!! AGRADECIDO
What type of sensors did you use?
How to write a program to work in line and turn to turn green when it comes 2 sensors or 3
Hello, how did you measure that the green part?
We have a color sensor on each side of the robot to detect
Hi good work
I have some questions about you robot, how I can contact with you ?
Hello!! I wish I could receive instructions for assembling your project. I'm from Brazil and I work with competitions. please get in touch.
Very nice
have you used arduino with ev3?
Just an NXT with multiplexer
@@skrima5376 ok
How many sensors and motors?

Do you have the building instructions of the robot?
wow
Another amazing RCJ project. Check it out:
