Since the automobile era, drivers have been obsessed with using as few wheels as possible. Not satisfied with the prospect of being completely disabled by motorcycles, single wheeled motorcycles were born. On the covers of popular magazines and other journals, these doom wheels of futurism attract all kinds of hackers. [James Bruton] is such a hacker. In the following video, you can see the second iteration of his 3D printing single round.
[James] “the wonderful unicycle is exquisitely designed. The bearing surface, gears, idlers, motors and double gyroscopes are contained in the circumference of the tire. The gyroscopes are driven by a considerable servo device and connected together by a gear that keeps the position synchronized. Their job is to always keep the single wheel balanced.
But as James discovered, the main difficulty with only one wheel is not lateral balance. Ask anyone who rides a bike and they’ll assure you it’s possible. The real trick is to balance the machine back and forth. Unlike the two wheel velocipede, a single wheel has no device to apply torque except a little gravity.
When [James] found it difficult, it was under the action of this front and rear balance that the gyro precession raised its ugly head. This concept is well explained in the video. We will not destroy the surprise ending, because the explanation and conclusion are very good, so we must see to the end!
If you want to see the first edition of [James], we introduced it here. If you are a bold man, maybe we will be interested in you. Let you see a two-stroke humanoid single wheel, which may end up in the emergency room. At least they wear helmets. Thank [baldpower] for your tips!
