I agree with Chris that this can be a viable strategy, but I think that the ceiling for this robot's effectiveness is even higher than his post seems to suggest. In that scenario the ceiling is equal to a purely defensive robot without the tube throwing capability, meaning there is no added value.

If the tube throwing robot is also capable of playing defense, they may be able to either effectively nullify a defender while simultaneously at least harassing the opponents offense or force the defender to let them throw tubes unhindered. If the defender hangs around while you switch to defense they are reducing their effectiveness, if they leave you go back to throwing tubes.

The distance the defender needs to travel to switch roles is much greater than the distance the tube thrower needs to travel.
