I've built many robots that use solid state gyros and accelerometers to make them balance - mainly two wheel balancing robot and ball balancing robots. But how can we use physical spinning gyroscopes to stabilise or make robots balance? I've built a Control Moment Gyro which uses a solid state IMU to measure the angle of roll of the whole device, and then tilts a physical spinning gyro powered by a brushless motor, so cause a perpendicular force.

Can you do a ROS robot start to finish tutorial? The last one you did from your Nerf robot wasn't a tutorial per se, and it was a little confusing. If you do a sharp solid tutorial from 3d printing the parts, using the correct motors, and setting up ROS and talking to the Arduino and trying to make the system work (the most important part), I would love you even more - if that's even possible...More importantly, the ones online use the Turtlebot which is really pricey for everyone. So simply, please, please make a ROS robot tutorial showing how to setup ROS and letting it talk to the Arduino to make the motors move with encoders. If this is really confusing, please reply to this. But thank you!

@mikefochtman7164 3 роки тому
While that certainly affects how it comes up to speed (and you can hear them racing around inside when it stops), I don't think that in itself affects the gyro's moment of inertia. Once everything is up to speed, I think it works as well as a solid one would. (IMHO)

pid loop tuning tip: start with i and d set to zero. increase p slowly till it starts oscillating, then try to increase the d gain to dampen the oscillations. Go back to the p gain and resume increasing. do this until you are unable to dampen the oscillations, then lower back to the last controllable value. For this particular case, the i gain should be unimportant, since that just ramps up slowly in case the p gain gets too low to drive the motor to the exact setpoint, which shouldn't be a problem for a balancing robot of this type since it's reacting quickly.

The rate of roll was just a matter of how fast they would pitch the gyro's fore-aft. (of course, those gyros were about ten foot across and really massive)

@PhaTs00p 3 роки тому
@@jamesbruton I'm just pulling numbers out of my ass. If I understand electric motor ratings correctly that's 1900rpm at 12V, at 60V up to 9600rpm. Ball bearings ~9cm from middle results in a RCF (g force) from 360 g (1900rpm) up to 9200 g (9600 rpm). Even if you do trust the plastic I strongly recommend balancing the wheel properly. Additional fun facts, assuming a weight of 4grams for one ball, the kinetic energy at 1900 rpm is around 7.5 Joules per ball, exactly the threshold muzzle energy you'd need a firearms license in Germany if you planned on launching the balls. At 9600 rpm we're looking at 180 J, about the same as a .32 S&W Long cartridge from 1896. Modern 9 mm ammo is around 550 J.
@benjaminrogers9848 3 роки тому
There's a Tom Stanton video on drone COG that explains why adding weight to the bottom made the balancing worse, broke my brain tbh
@blahorgaslisk7763 3 роки тому
Thought of that, or perhaps a similar video, when he added those nuts. I still can't wrap my brain around exactly how it works, but when I watched the video it was explained so well it all seemed perfectly logical, which I expect it is. But now I can't remember the details and it sounds totally weird again. I remember it being explained how adding weight *above* the point of balance was much safer. Also how it got easier the further above the balance point it was. Kind of like how it's easier to balance a three yard stick on your finger than a foot long stick with the same weight. All in all it hurt my brain... Oh no! It's coming back to me. The problem with using a weight at the bottom to balance a helicopter is that as the craft changes direction the weight will act as a pendulum. Go forward and the weight will make the craft tilt forward. The more the craft tilts the more power is projected backwards accelerating forward which will make the pendulum force the craft to tilt even more and so on. Same with air resistance which will cause the craft to tilt in the direction it is moving or if it's wind then it will tilt towards the wind. All in all it becomes very unstable. With the weight above the craft will tend to tilt in the opposite direction, effectively counteracting the tilting effect of the acceleration. And so the craft will be more stable but less maneuverable. Ouch! Brain not happy that it actually had to work for a few minutes there... Now I can't immediately visualize how this would influence a gyroscope. Late night here and my brain says it needs it's rest.

This reminds me of when I spun up an ancient 8MB, 8 platter HDD, it was huge and I could very clearly feel the gyroscopic forces as I tilted the drive. That was cool.
@blahorgaslisk7763 3 роки тому
There was a reason those huge 8" and larger drives were so heavy and in some cases even bolted to the floor... The largest (physically) drive I saw had a aluminum drive enclosure that was about a yard across. There were a drive axle sticking out with a freaking pulley on it and a belt connected that to the drive motor. A belt driven hard drive! It seems so insane now. And I think it was something like 30 MB of storage! But hey, it replaced a few of those 8 disk drive stacks that they were throwing out. I think those stored somewhere around 450 to 800 KB each. I may be way off, but this was around 84, perhaps earlier. Can't remember exactly. That "new" hard drive was not only way higher capacity than the drive stacks it replaced but also very much faster and more reliable. I did work on some 8" drives later, say some time between 86 and 90 or so, and those were about 30 MB and on their way out then. It was kind of hilarious. You had a tower computer with a controller card that connected it to a second tower that was almost exactly the same size as the computer and that held one 8" HDD that could store about 30 MB. I'm trying to remember the brand but it's hard. Priam keeps popping up but it doesn't feel quite right. Googled and yes it probably was Priam. Damn brain, you did good!

Interesting stuff, although I have to agree I am a bit worried about that rotor bursting. I think the control would work better if the output of the PID controller set the servo rotation speed, rather than angle. The torque reaction from the gyro is proportional to the rotation speed of the gimbal. Then, to keep the gimbal position, from tending to infinity, an outer loop that reads the gimbal position and alters the target lean angle.

You have essentially stuck that IMU out on a springboard, you can see how much it is vibrating, that will probably affect the roll calculations and add a lot of noise and hence affect the whole control system.

this is just like the two-wheeled electric car designed by lit motors. counter-rotating counter-processing reaction wheels for stability control are also used in the Hubble space telescope to keep precise track of its view. however, rotation of the counterweight becomes ineffective after the axis or rotation aligns with the axis of the vehicle rotation a secondary desaturation force is then needed to realign the wheels to take the rotational energy out of the system. satellites such as bubble use thrusters or magnetometers to achieve this task. thus while on earth, it advantageous to change its stance such that gravity itself acts as the reaction force to remain stable against any outside force.

A gyroscope offsets the force by 180degrees can you use 2 counterspinning gyros for better stabilization with no motors

I think the biggest problem is how sluggish that servo is. You can see how much it lags when you first demo it with the potentiometer. Try one of your cycloidal gearboxes and a brushless motor for a more snappy and responsive setup :)
