Walking robot with balls for feet

Crazy question from one of my teams… They would like to know if they built a walking robot with feet that gripped the orange game pieces in its feet, and walked on them, could the robot then legally walk into the scoring zone? Note that the balls would be touching the scoring zone, and the robot would only be touching the balls.
I’m not sure myself how that would lead to any advantage, but it is creative thinking.

This strategy does not appear to violate any rules, thus would be legal.
