Just to show that physics is fun... the Classic Space self-righting mono-wheel!
About this creation
After noticing that Llwyngwril Space Systems seemed to have cornered the market in outlandishsurfacevehicles, the managerial team at Beyond Midnight Engineering unwisely concluded that the outlandishness of their designs was the secret of their success. Their first attempt to cash in on this supposedly lucrative market was the Weighted Externally Elevated Balancing Landranger, generally abbreviated to WEEBL-1.
The flywheel-balance system imposed such tight weight limitations that there was no storage space, windscreen, or even mudguards, which made getting into the driver's seat fairly hair-raising and traversing rough terrain even more so. On the plus side, the high driving position gave excellent all-round visibility.
The small pontoons hanging from the lateral axle were not required for balance, but an attempt to add some sort of additional utility to the vehicle, by allowing owners to attach cameras, geological scanners, sample collectors and the like. Unfortunately these valuable pieces of equipment tended to get knocked off and smashed at the slightest collision, much to the annoyance of WEEBL owners.
When receiving complaints of this nature, BME sales reps were quick to point out the small print in the sales contract indicating that the company could not be held responsible for any after-sales modifications made by the customer. And why not instead focus on the vehicle's excellent ability to roll over quite large obstacles? Advice that one disgruntled customer immediately put into practice.
Apparently MOCpages doesn't like me embedding videos any more, so to prove it really works, see it in action here and here! Got to love that centrifugal force. Or rather, centripetal.
Here's where the magic happens: initially the counterweight was made out of regular bricks, but this wasn't heavy enough to balance a minifig, even with the minimalist cockpit. Fortunately, a double layer of M:Tron magnets from the BME stockroom did the trick.
Frightfully silly! I was wondering how to make something like that turn with an RC motor, possibly servo some weight to one side or the other in forward motion. This could be the start of something truly ingenious. Absolutely crazy design and fitting competition to Llwyngwril Space Systems. Outstanding!
