这几个飞轮电机功率得多大啊
What a cool guy! Tell me where I can get the theory of how this system works?
Can you share code, schematic etc.Thanks
Balancing a invaluable high end balancing system on a can of coffee.. priceless
Beautiful video a piece of art😍, in amateur rocketry rockets starts rolling does this has anything to do with Coriolis effect?
Did you publish any research papers on this. Which type of communication did you use, and how to set those angles
Did you implement PID control?
Did you machine your own wheels or did you purchase them?
Amazing. Is this technology actually being used for the satellites ? I have no idea.
yes almost in every satelite
@@TheDMojoOF thanks for the reply
You should mark the wheels to better wiew rotation speed
what happens when all the wheels are shut off it slides back to how it started?
so this is powered by soup?
核桃,哈哈
How much thrust do you get from precession?
Zero.
@dsdy1205 well balanced! Are you planning to add thrust?
@kmyase1 I'm not the author of the video, but in general you don't get any cumulative thrust from precession
Hi, Want to know where it will use, Awasome Reaction Wheel 👍👍👍👍
I have a proposal to use this to create thrust for satellite and spacecrafts. if you are interested, let me know i can send you my design.
@@kmyase1 that'd never work, you can create torque, but not thrust
Enough n now v don't need additional requirements.....
核桃牌的嘛

Can you give me the model number of the engine?
How to control its attitude using this reaction wheel configuration???
congrats!
YAW-BOY!
Seems like there is a lot of friction in that air bearing. The platform barely moves in between of maneuvers. And there seems no precised orientation information sensors: opto-fiber angular velocity sensors or sun sensors. Seems like fake somehow...
I mount a 9DOF sensor on top of the device . Airbearing has little friction indeed , but it satisfies our preliminary tests.
it is moving by changing the rotation speed? there are other solutions haveing fixed rotation speed an tilting the motor axises
Yea but think bout it, titling the motor axes require more motors/swerves tht take more energy, making it more complicated unnessecarily
what is the difference between an adaptive control and a PD control?
Fucking love that its sitting on a can that used to hold some kind of snack..
zat aint snack, zats walnut powder
That's typical university life. Not fancy, just get the job done with what you have.
I realize I am quite randomly asking but does anybody know a good website to watch newly released tv shows online ?
@Ishaan Ayden i watch on FlixZone. Just google for it :)
@Luka Hudson Yea, have been watching on Flixzone for years myself :)
Love it.
电机名字:核桃
哈哈哈哈哈哈一眼看到核桃
Can you briefly describe what is going on behind the scenes here?
please?
Satellites don't have fuel to rendezvous.. Instead they have circular spinning wheels called as reaction wheels in all axis opposite to each other..
@@shankarrathod9914 I understand that part. I was more so wondering about the electronic controls and what he's using to induce the different degree'd rolls
@@Astro_Shaniel At the start of the video, it says he uses PD controls and that means he's computing the actuator's input by a gain value multiplied to the error state and error state change
@@akshayelangovan7764 you mean PID controller its like a quadcopter with Kalmar filter PID controller gyro/accel sensor, ESC etc......
Hello! Do you have published articles on this project?
What kind of motor are you using?
By the looks, Maxon EC-45 (70Watt)
cool
