This is Hacker Public Radio episode 3524 for the first day of February 2022.
|
|
Today's show is entitled, Wheels at Endham, How to Reliably Attach Wheels to the AR Robot
|
|
Platform.
|
|
It is posted by mechatrolyak, and is about 7 minutes long, and carries a clean flag.
|
|
The summary is the most difficult part of most apocalyptic robotics, how to keep the wheels on.
|
|
Greetings, this is mechatrolyak, the mechatronic for Hacker Public Radio and bitchute.
|
|
This is an addendum to the last podcast on Hacker Public Radio about making your smash buggy,
|
|
which I described attaching your motors to your chassis that you've chosen and making a simple
|
|
crash buggy just to see what can be done.
|
|
So I thought I'd do an addendum here about wheels.
|
|
I had an opportunity to fix the wheels on the Herald Interceptor, one of the wheels had come off.
|
|
So let's do that.
|
|
So here's a chance to look at the motor spindle without the wheels on directly.
|
|
There's your two screws that hold the motor on.
|
|
Make sure those are tight before you put the wheel on because it'll be difficult to adjust them
|
|
afterwards.
|
|
The center hole is for that spindle hub on the motor.
|
|
For this one, the chassis is a hard drive caddy bay type thing from a tower computer and all
|
|
those holes were already drilled for me, which is perfect, except one is kind of offset.
|
|
So I have one wheel that's about a centimeter more to the front than the other one,
|
|
but it doesn't make a difference.
|
|
Okay, so the wheel itself consists of a printer roller that's part of the paper path.
|
|
Like I said, you take apart two printers that are the same.
|
|
You're going to have four motors.
|
|
You're going to have a bunch of these wheels too.
|
|
Unless you have a motor with the gear on the spindle that fits perfectly inside of this hub
|
|
on the wheel, you're going to have to make your own.
|
|
And for this one, it's a piece of coax cut into one centimeter length with the center conductor
|
|
taken out. So that center space becomes where the spindle fits on.
|
|
There's some electrical tape on the outside just to make it fit.
|
|
And I think I used just plain epoxy to fit that hub onto there.
|
|
We're going to use JB weld to actually attach it to the spindle and make it work.
|
|
So JB weld is pretty much the only stuff that works that I've found.
|
|
It's that steel infused epoxy.
|
|
So you mix up your two bottles.
|
|
Attach it to the wheel parts.
|
|
I mean, attach it.
|
|
I mean, apply it to the wheel part and to the spindle.
|
|
And you just throw that on there.
|
|
And you wait.
|
|
You wait about 15 hours or so.
|
|
You might have to put a shim in.
|
|
I just use one of the bottles here as a shim.
|
|
Just to keep the wheel oriented the way I want it to be.
|
|
Because it can kind of move while it's drying.
|
|
So keep that in mind.
|
|
You're going to want your wheels all lined up.
|
|
So your high performance mechatronic vehicle does go where it's supposed to go.
|
|
And I've done a bunch of testing and it works really well.
|
|
Yeah, lots of torque.
|
|
Lots of torque on this high performance vehicle.
|
|
It really likes a smooth, like lino-type surfaces.
|
|
Outside on sidewalk or whatever.
|
|
It's not as good with the concrete, a lot of bumps and vibration.
|
|
This is a real street sport style.
|
|
It's got street suspension, like no suspension, real sporty suspension.
|
|
So it's very responsive, very fast.
|
|
And that's it.
|
|
Yeah, so wheels, the most difficult part.
|
|
But I think we've got it.
|
|
If you develop your own wheel technology, I'd be very interested to see that as well.
|
|
All right, as mechatronics signing off.
|
|
This video is being uploaded first to BitShoot.
|
|
It's a bit of a switch since I did the narration on the video itself.
|
|
Rather than podcasts like the previous ones.
|
|
So next time we will be
|
|
putting it together with Arduino and a H bridge.
|
|
So I hope you've all started gathering your printers, start taking stuff apart.
|
|
And you have some parts.
|
|
For your post-apocalyptic robotics.
|
|
It's been mechatronics signing off.
