Wooden Robot Class

Re: Wooden Robot Class

BizaWood I believe if that's the one with the saw blades.

No there was a place for Mr. Pink but, I lost my Sat Nav, I needed it to give me some guidance.

Right now I'm kicking myself but there are still more event this year.
I just wish I had gone to this one as my first.

Re: Wooden Robot Class

Yeh that's BitzaWood.

They're threaded inserts. You just pilot an 8mm hole, crank in with an Alen Key, et voila! Instant M5 thread to bolt to.

I got the idea from the Gimson drive units, except those require a press since the inserts go into Nylon.

Shame about not making it, I've been nagging RoboChallenge about hosting an event August/September time so in the middle of the year, but I think some of the UK guys are going over to Mad Metal Machines in Germany in September since they run a Full-Combat FW event.

Re: Wooden Robot Class

Are those the ones with a threaded outside to them as well as a threaded inside? We're did you get them as I tried and could only find places to buy several hundred of them!

FYI I put threaded inserts into hdpe by just clamping them in with a vice rather than a press.

I used this guy: (And the wooden type obviously)

Re: Wooden Robot Class

So who's making a robot for MMM this September?

Hopefully BitzaWood will be working by then......

Re: Wooden Robot Class

Managed to finish off BitzaWood today. Although it's got some ESC issues. Used the same type that Guilherme had in Galactus but there is a major delay (1-2s) between Fwd and Rev, which makes it near impossible to drive.
It also doesn't failsafe on the drive at all!
Changed the weapon control to one of those Turnigy 30a £8 controllers, works nicely and failsafes.

Here are some photos, I'll chop up some wood at some point:

The Insides (Almost Jamie compact in there!):

Re: Wooden Robot Class

Very nice PJ, I approve of the compactness!
I assume you made the clearance cutouts for the discs just by spinning them up and putting the wood in place?

Re: Wooden Robot Class

Cheers!

Haha, well I tried to cut them before hand, but I was a slightly out on my measurements shall we say....

So yeh i just screwed everything in place, spun up the blades, some saw dust later et voila! Perfectly fabricated cut outs.

Re: Wooden Robot Class

How much does Bitza Wood weigh? No where near the 13.6kg limit am guessing. I am very tempted to build a wooden Conker now! with 200mm saw blades :twisted:

Re: Wooden Robot Class

All the expensive bits can be kept in a metal box in the heart of the robot.

I have been designing an 'suicidal robot' for the robochallenge 'tested to destruction' shows and Jamie pointed out that I might be able to use it in the wooden class.

[attachment=0:u7qb2wv6]Internal Reveal 01 S.jpeg[/attachment:u7qb2wv6]

the metal blade at the front would be swapped out for wood but is the metal chassis underneath legal? (Its Mild steel box with a Ti mounting plate.)
It was designed so that the outer layers of wood (2x 18mm MDF) could easily be ripped up by spinners for the shows but the expensive bits would have a bit more protection in the centre.

Thoughts?

Re: Wooden Robot Class

I'm yet to weigh it, but I reckon around the 10kg mark. May make a Titanium drop on shell and use it for whiteboards at robochallenge events.

I think a steel chassis sort of negates the nature of the wooden robot, but if we're at an event together I'll happily have a fight (mine all wood) to put on a show and have a laugh. Especially since there are no other wooden bots.

Re: Wooden Robot Class

For those going to MMM in Germany, the Raptor class is 6kg max and no brushless stuff. Wooden robots could do quite well in those.

Re: Wooden Robot Class

I will use a wooden base. If it gets to the stage where I am worried about the internals being damaged you will have probably won the fight anyway

Re: Wooden Robot Class

as soon as minor tom is finished i will be building a wooden shell for it so it might be ready for the maidstone in october f any of you guys are going

[Eventorizon]

Re: Wooden Robot Class

Is anyone going to the leeds armouries event? Would we be allowed to run the wood saw blades in that arena? I know its not designed for spinners but they are hardly NST or Little Spinner-esque.
