Yes, and no.

Remember, the bins have to placed on the playing field so that the "lid" side is up. They cannot be placed in any other position.

In this orientation, the bins have the least amount of friction, so I doubt you will skew the robot's path.

But, as for placing a bin in front of a robot, yes, that is perfectly legal. I was thinking about that strategy too. If someone programs their robot to look for reflective tape in an attempt to knock over human player container stack(s), you could put a bin in front of it to fool it.
