My problem is:
1, the robot picks up a piece at station 1
2-rotates up to the station 2
3-in station 2, the robot turns its head, picks up the a piece ready
4-turns its head again and puts the piece removed from station 1.
5-rotates to the station 3 and puts the piece removed from station 2.
6-Then the robot returns to station 1 and restart the cycle.
Thank you, in advanced
