So I'm doing this project using an EV3, here are the tasks of the project:

  • We have to save the path that the robot will take manually ( we will move the robot by hand and it'll save the movements) so we can run it again automatically

I'm confused about how to do that exactly, any help would be appreciated!

If your robot has wheels, then measure or calculate the circumference of the wheels. Then you just have to count the rotations of the axle and multiply by the circumference to get the total travelled distance.

I'm deliberately only giving pointers instead of solutions, since if it's a project with tasks, then you are supposed to learn about it - if you're still stuck, tell us where and how, so we can give you further tips and pointers to help you learn.
