Making BB-8 (v2) - Adding Gyro/BNO055 IMU - Part 4

[@theviper1999uk]

honestly I think you're a KZbin who puts the most effort into his work

[@Jiu-JitsuJourney257]

I have absolutely zero knowledge in this field but I am infinity fascinated.

[@makr2092]

Used a PID controller on mine. Much easier than expected, and made a huge difference. I now use them for almost every motor project :)

[@RimstarOrg]

Yeah, I'm looking forward to trying a PID loop with it. I'm playing with a number of algorithms now that the electronics is in place.

[@USWaterRockets]

As others have said, you should switch to a PID loop instead of trying to come up with an algorithm to keep it stable. This is the type of application that PID was made for. Our IMU controlled rocket stability experiments really drove this point home, and we'll be doing some video on those test results. You'll be really pleased with how well you can get PID to work.

[@RimstarOrg]

I'm away this week but I'll be trying PID when I get back.

[@electronicsNmore]

Cool module, it must be the same type used in hoverboards.

[@MrGoosePit]

Looks amazing and keeps getting better! Great work!

[@GuruBrew]

Interesting with great progress

[@narayanbandodker5482]

Really amazing build! Have you heard of the PID algorithm? It can be used to stabilize movement, but hard to implement

[@RimstarOrg]

Thanks! Now that that electronics is in place I'm trying a number of algorithms, including PID. Arduino has a PID library that simplifies it.

[@JamilKhan-hk1wl]

I would suggest you to have a buck converter to supply 5v to arduino and other boards as arduino's power supply is not that reliable when many things are connected

[@MohammadOmarSalameh]

nice upgrade, what About all these battery, how to charging it, two for motor, one for Arduino and one for RC

[@RimstarOrg]

I'm glad you like it. I describe the batteries motors and so on in my part 1 video here kzbin.info/www/bejne/eHS7eWd3g5eUpck. You can also find it all on my website here rimstar.org/science_electronics_projects/bb-8_star_wars_droid_v2.htm.

[@gogleg4]

Rimstar, have you thought of using an ardupilot board such as the old APM or new PX4 mini? These boards come with a plethora of sensors, and modifying the firmware is not all that hard. Indeed I think it would make for a smooth and stable BB-8

[@RimstarOrg]

I hadn't heard of it. I'll have a look.

[@XXCoder]

I wonder if can modify it a little in order to have counter-pressure on other side of ball so it cannot slide around inside?

[@RimstarOrg]

I already does. There are two rollers, one on the front end and one on the back end. You can see them at 9 minutes and 18 seconds into this part 1 video kzbin.info/www/bejne/eHS7eWd3g5eUpck.

[@XXCoder]

Oh I meant the opposite of bottom, meaning top. Sorry for being vague! :D

[@RimstarOrg]

Ah, thanks for clarifying. The head kind of does that already. If you can picture it, the magnets inside pull on the head magnets and the balls in the head then put downward pressure on the top of the ball. So indirectly, the drive system inside is gripping the top of the ball already.

[@XXCoder]

Hmm yeah. Thanks.

[@gregtasi]

That's amazing! Great job! :D

[@mechanicalboy9590]

What's about the sensor accuracy? Please answer me

[@RimstarOrg]

I don't know. You can download the BNO055 Datasheet here learn.adafruit.com/adafruit-bno055-absolute-orientation-sensor/downloads

[@hussein12marie35]

I like it

[@Grizzly_Lab]

Wooooooow, now the next question I guess would be: when are we gonna see it on an actual Star Wars movie? o.O congrats, you're really a maestro on this ;)

[@RimstarOrg]

Thanks. Yeah, that actually happened to R2-D2 builders. They got so good at it over the years that for the recent movie they just used droids from builders rather than going to a special effects shop.

[@Grizzly_Lab]

Yes, I remember something like that, so I was wondering if we're gonna see your creation somewhere. It would be super-duper-cool, indeed ^_^

[@pabloodysseussanddrawingro3420]

Pablo use BNO055 to keep the north

[@chickennugget2248]

genius.

[@peshozmiata]

1:36 "It does look like shit."

[@junherrera9343]

vin, pin, sin, din, ... those terms is making me drowse .... hehhehe, love the video sir, but my head hurts on what the terms you are using, .. thanks

[@akepatinagaraju8564]

👍👍👍

[@attilarivera]

Bb8? Looks like friend of mine lol. He os always drunk and he is fat.. ..... Wait.. who's Ardoino? Any mexican guy? Lol

[@Aperson-sv2hc]

Whoah... Second comment, 48 min. Of silence, wow this be small.
