YEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH

No, its Andrew-powered-Switching last time I saw it !

Forward ! *Sparkage* - Smoke, Flame, steam (it was raining)

Its got a home made rotatry mechanical -pwm controler but i didnt have it set up when the video was taken i just used the switch gear with out it spinning as on of switches manualy operated by me we have some video of it driveing under remote control but its curently only on tape .

That is nice. I'm building one at the moment that will handling an ice pick like weapon under the power of pneumatics. I have made a model and it seems to all go together so far... but you'll all have to wait for more stats.

I don’t think building a new heavy weight is necessarily a good idea at the moment; we have put all our heavyweight stuff on hold. Bulldoze is being modified to run UltiBot’s rules at 50kg.
There are currently no local plans for any sort of heavy weight comp that I know about other than Robowars no spinner all terrain idea and no one seems to have time money or interest in pushing that along at the moment.

Of corse there is always the bragging rights; having the only NSW Heavy etc.

There is not a lot of hope as far as free trips to Pommie land these days.

If you wont to build a heavy and take on the Yanks good luck.

We'd love another builder of featherweights down here, they're cheaper, easier to move and just as fun as heavyweights, plus theres's already a thriving comp for them!
If the bug is still biting then build a heavy with the info you gained from your featherweight.

It would have been a bit better to know that you fellas at Rotwang had put ur stuff on hold a little earlier because as this year started i had to start designing, buying and building.
I was going to come out with a heavyweight robot, it just looks like i won't have much to do with it when i am done.
Heavyweights were the things that got me hooked and it's more an issue of satisfying a 11yr urge and getting a good HSC mark now that i have started.
This bug has already bitten, i'm making a heavy.

Buy us a pair of $1200 speed controllers for our heavyweight and we'll battle you

Hey man, your doing the exact same thing i did and thst make a robot for year 12,it was ok but heavyweight maybe isnt best way to apprach it.

Personally i reckon make a kick ass lightweight as its still biggish and all but is still competable and coolish.

Whats details like drive/weopon etc etc.

Best of luck with it, if your interested my year 12 metalwork project was called the lockjaw project, have a look in build thread if your interested in seeing what another school boys done when hobby and school collide.

*bang*
I think even a middleweight would be way smarter to do, as welch your bot was basicaly one of them... you never would have competed with it eh.
Did you even get a video of it running?

Your concern is noted and i'm flattered that you care.
The angle i will approach this from is i will put all the components i have already together and go from there. in all likelihood its gonna end up a heavy. my frame is 25x50 box section MS and will be using in excess of 4m of it. on top of that the batteries at 5,4kgs ea + pnuematic gear its gonna be heavy and i dont think weight reduction will be one of my priorities. I just need 2 finish it.

What speed controllers, motors and batteries are you using? what pressure is your pneumatics running at and have you any prior knowledge/experience?

The short answer is no, i have had extremely limited exp with pnuematics. We have a propagation nursery and the seeding machines use rams with a stroke of 4-10cm that run at about 50psi to push around trays. thats it.

The local pnuematics expert at New England Hydraulics said that i need 2 build the frame and axe setup 1st then they'll figure out the kPa and length of the ram to suit it. He was right into the whole concept of robot wars it was great

Motors- 2 x 24v wheelchair motors that run at 180 rpm at the drive shaft.
Speed controller- Vantec RDFR47E
Batteries- 2 x Odyssey 12v 14Ah Drycells

Nice. Have you already bought the Vantec?
