Thanks for sharing your work Team!

I have the following questions:

  1. How many ball sensors you have?

  2. You mentioned your software do value modification according to the conditions. Can you give us more details about this?

Nice work on improving your robot!

If I understand correctly, the robot moves faster if the values of the ball sensor are low, and moves slow if the values are big. What is your strategy behind this behavior?

You also said that now you have more speed and power. Is it only because you added another wheel? Or did you also change the motors?

Thank you for your question.

  1. Both robots have four ball sensors.

  2. For example, if the ball is in the back of the robot there is a lot of back and forth movement, and conversely if the ball is in front of the robot there is a lot of left and right movement.

Thank you for your question.

It moves small ,because of quickly touch the ball.
Also it moves large ,because of to goes to between the ball and the goal.

The big factor is the change from 3 wheels to 4 wheels. Another factor is the increase in battery from 7.2V to 8.4V.
