This assignment was such a pain to work, I struggled a lot brainstorming how to get pathfinding to work in order to both avoid obstacles AND track the objects the robot needed to pick up. Ultimately, I decided to work on one thing at a time and made a copy with no box collision to have the robot pick up one item at a time and bring it back until there's no items left on the left side of the screen:
After that was working I attempted to add collision to the boxes to make the robot go around the boxes when it runs into them, which turned out poorly:
I think if I were to do this assignment again I would struggle just as much with it as I did the first time, as I don't know much about making a good pathfinding algorithm.
