Re: Team Bitza

Any idea how big the RC arena is corner to corner?

Pretty sure it's 5m x 4m

Re: Team Bitza

care to share your link to the mythical motors?

sorry if that was confusing

Re: Team Bitza

I was going to keep it a secret, but I think it'll be a bit anti-climatic so I'll just say.
They're car fan motors, overvolted to 24v. Managed to find a matching pair, also found some incredible wide wheels to put the power down with.

Next question!
On a spinning disk with 3 legs connecting the outter rim to the middle will it throw the balance if I put 2 teeth on opposite sides?

Re: Team Bitza

it shouldn't if there even

Re: Team Bitza

Since no one wanted to come play with the wooden robot idea and I had already made one I figured I'd do something worth while with it!
And so was born BitzaWood Revo

In keeping with the Bitza theme the disk is a master pulley from a V6 Modeo (Ditching the saw disks as they'll in ineffective against metal)
The armour is 2mm Stainless that I was given (odd shapes hence the multiple parts)
And I'm swapping out the MDF lid for a HDPE one courtesy of Mr Weston!


No disk yet, but shows off the Ti front skid (Left over Ti from Bitza)

Got some Polycarb for the link cover. That way the light can shine through.


Disk, Bush and Tool Steel for the teeth:

Re: Team Bitza

I am in on the wooden robots but its back home so no pics, imagine La Machine with 4 gr01's, has the potential to have a saw blade fitted to it. Don't loose Bitza Wood!

Re: Team Bitza

I'm designing it so it can just got back to being only wood.

Don't know why the images are no longer loading. Here's the album:

Re: Team Bitza

I was watching your robot on youtube and in every video I've found Bitza is still wandering around at the end! It's like the most rugged thing ever! Fair play to you for recycling parts n still having an uber reliable robot lol!

Re: Team Bitza

Its kind of ironic... Bitza would keep going through pretty much anything. Now Bitza 2 gets stuck on pretty much anything. Go back to the original design :-)

Re: Team Bitza

Haha Cheers!

Bitza Mk1 was very tough but had no offensive capabilities, it just sort of bumbled about surviving.

Bitza Mk2 was a rush at the end and as a result had some serious flaws, hopefully next April we'll have found a common middle ground of offense and reliability.

Re: Team Bitza

I'm two thirds of the way through building the most basic of basic robots and it's really hard lol. I have this huge new respect for the people that do this and compete, even with a basic robot as there's loads and loads to learn. I'm a computer/server engineer by trade so I'm not clueless, but 'making stuff' from scratch is ace, and your robot has the whole ethos I have, ie 'what do I have lying around I can use to make this'.

Re: Team Bitza

Unfortunately it makes everything inherently heavy! Which at 13.6kgs is a real problem, but the amount we've learnt is invaluable.
Luckily Dan is now at Uni and has access to some nice equipment, so we've pivoted a bit and aren't quite as Bitza as before but still having fun and that's all that matters.

Re: Team Bitza

Question:

What is the reduction relationship between planetary gears (The Pinion and Ring gear)?
Am I correct in thinking it's the same as Spur gears, as in a division between the amount of teeth/circumference/diameter on each gear?

Cheers!

Re: Team Bitza

Yep, its identical
