Welcome to the gyroscope forum. If you have a question about gyroscopes in general,
want to know how they work, or what they can be used for then you can leave your question here for others to answer.
You may also be able to help others by answering some of the questions on the site.

Great topic. Gyroscopic precession has no moment of inertia and this cna be used for more thing than talking. Here is a device that was made by me that uses gyroscopic precession for propulsion. This propulsion theoretically can be used in space...What do you think about it?
Your machine has all the elements required for propulsion but suffers from the common problems that I, and I am sure others, have struggled to overcome. This, apart from time, engineering ability, money or an engineering savvy friend, is the age old problem of getting the gyrodynamic forces large enough so they are not swamped by the useless non gyrodynamic mass of the mechanism, frame, power source and motors. Without better gyrodynamics (or lighter mechanics) your device is doomed to be written of by all but the cognoscenti as yet another example of a “slip/ stick” effect.
While Sandy’s reply saying that your machine would only work within a gravitational field may be technically correct the effect of gravity can always, I have found, be replicated by other force producing devices as simple as a spring or even an elastic band. In space it would also, of course, require a mirroring machine to cancel out the torque of a single machine.
As Sandy said in his reply to you; good luck, though don’t go crazy on patents yet as one of mine predates where I think you are going and would constitute prior art. And, as you probably have discovered, the device will only produce movement in discrete packages (impulses). While the fact that it punches a hole in the third law is fantastic and it may enable further improvement as understanding improves, it is pretty useless for propulsion if constant acceleration cannot be achieved.
As your post is buried in amongst old answers that most will not find I shall also copy this to the new questions section so more can see your video link.

| ||Hi Kristian|
An interesting machine. It is a variation on the constant velocity machines or inchworms , walkers etc that others have posted on the forum. It is based on Prof Laithwaite's patented 'up as a gyro, down as a mass' principle and has the same limitation. It does not accelerate the inert mass, only displaces it.
I interpret Sandy's comment as it will not overcome gravity, it cannot hover. As Nitro says gravity can be emulated by an elastic band. Your model will work in space if you attach a mirror image of it to itself!! You will then have a space paddle or a means of maneuvering around without reaction mass! Discussed elsewhere on the forum.
Your model adds to the growing number of examples that show the current paradigm of Newton dynamics is incomplete, as such it has value. If you do get a University Professor to give a considered opinion, I for one would love to hear it.
Good luck with your endeavours.

| ||Nitro, please read this whole post and comment on it. I am in contact with M-Thruster and shared my ideas with him. I hope that one of us or someone else will finish this.|
Look at this video:
The reason why it is easier to lift the gyro wile spinning is because it has no inertia. Tthe weight of the gyro is still the same it just has no inertia when he is lifting it wile precessing. That is why it feels lighter...he does not fight against the inertia. You can see this when he is on a scale in the next video. When he lifts the gyro wile standing on a scale the needle of the scale wobbles around one weight, it only massively changes at the end when he returned the gyro down...BUT without a precession, he just put it down. That way it has inertia and it showed on the scale.It is on this video:
Please look at my device:
You must understand the most important thing. .
The most important thing is that the precession must stop with precession. What this means. Imagine you re in space, weightless and no air around you. Your arms are spread and you flap them once as a bird and stop. Will you move? No you will not. Why? Because the movement of the arms DOWN will cause opposite reaction by the Newtons law, and when you stop your arms this force will be equal and in the opposite direction so you will not move at all.
Now this is why the movement of the arm must be stopped by precession.
When you rotate the device the arms go forward due to precession and this movement is without inertia. When you stop the gyroscopes rotating action the precesson stops and the arms go back due to centrifugal force. But if you don't stop this movement by another precession (start the rotation of the arms) the force will cancel itself (same as that astronaut). But when you stop the back motion of the arms (caused by the cetrifugal force only) the inertia is cancelled by precession. In this case the astronaut an move forward. That is why you get a forward motion.
I shared all this with M Thruster on youtube. He is reluctant to communicate even though I think he can tweak his device much better. Hop he will listen, I'm sure he will.
