Hovercraft Battle Bot

[Ocracoke]

You could have a completely solid skirt (as older hovercrafts were constructed with) but that would need to be fairly lightweight to allow the robot to hover and still have the potential for breaking (fibreglass would be a potential way of doing that). Then again, with a powerful enough motor, anything is possible.

As for a weapon, a good overhead weapon (i.e. a fast enough axe or a crusher) in the right place would mean curtains for the robot for movement but as you say, a horizontal weapon, such as a spinner, would be less effective. Heck, if it rose high enough off the ground, low slung spinners would be ineffective but then at what point does it become a drone?

My main concern would be control. Airbrakes in addition to movable ducting on the engine might make it somewhat controllable. Also, what weaponry would work on a hovercraft? Anything pushing (spinners, axes, rams, flippers etc) wouldn't work as there is no grip on the floor. As a distraction half of a clusterbot, I can see this working with the other bot being a "traditional" robot mind.
