I disagree a robot with a front mounted harvesting device that can simply run over the balls to pick them up will be easily able to pick up an empty cell (without stopping) that is dropped to the ground moments before the robot arrives at the outpost. The robot can than continue moving and possibly even turn (with the traction from the carpet) and get it to the fueling station. I don't think moving an empty cell is any different than moving a moon rock to fueling station and we know many teams will be simply doing that.
