How can this not mention the Gyro-X [0]??

I remember reading about it as a kid in the late 1960s. I still remember it saying that the owner could play with other motorists' heads by leaning the car out in turns.

Well, it _is_ wikipedia. You could add it.


I came here to post the same thing!

The fuel economy on this was said to be excellent (because it's a tandem seating design), with the downside that the passenger was always relegated to the back seat...

Gyrocars also featured in the awesome science fiction novel Sinister Barrier, by Eric Frank Russell (published in 1943!).


There's also a Gyrotrain http://blog.sciencemuseum.org.uk/louis-brennans-gyro-car/ and this much more detailed wikipedia article https://en.wikipedia.org/wiki/Gyro_monorail


There's a nice model of a gyro monorail shown in the video here: https://www.youtube.com/watch?v=jGYXJjRfgTM

I may be possible to do the same with Lego Mindstorms - certainly you can make self-balancing two-wheel robots: http://robotsquare.com/2014/07/01/tutorial-ev3-self-balancin...


My question is this: Why have two wheels at the bottom, and two complicated spinning wheels in the center, when you can simply have 4 wheels at the bottom? :)


Things that come to mind: less rolling resistance with 2 wheels, faster turning since you can lean, simpler mechanics in some aspects (no need for a differential), easier to build narrow vehicles with better aerodynamics.


Why have four wheels at the bottom, when you can simply have two on the bottom and two in the centre? :)


Why not just use transitor-based gyroscopes and lever the vehicle one way or the other when turning to keep the riders level? In other words, why not just treat the carriage portion of the vehicle like a large gimbal?


This company [1] seems to be working on a modern version of this, but it seems like their website hasn't been updated since 2012. Anyone know of the status this projects or others alike?

I was thinking of gyro-powered space launch assistance not unlike railgun. An inexpensive way to give rocket with all the fuel 150 mph on the start.


But then you need to build the rocket to have reinforced attachment points for the rail sled and be strong enough to withstand the lateral forces during the rail launch, with the attendant cost in increased weight.
