Interesting to see how this will play out.

As for intentional herding, it should be pretty easy to make a deploy-able mechanism that sticks out the front of the robot, in front of the bumper, and can actually herd a game piece in a controlled manner.

But controlling a game piece with just the bumper, with the bumper rules the way they are, seems a bit far fetched. When you turn the robot, the game piece will not stay in front of the robot.

I wonder if this is why the rules are worded as they are?
