Propulsion that does not involve driving wheels

[ebarker]

a prediction: true or false.

"the use of a fan to increase the downward force the robot exerts on the floor will not be allowed if it exceeds 120 lb force."

you could weight or blow yourself downward up to 120 lb force. weight don't use batteries.

But the idea of using fans for horizontal propulsion even though that sounds cool would be noisy beyond description. It would bring the discussion on OSHA noise levels to a whole new level. It would create havoc on the noise front.
