Re: Graupner motors

PLEASE JUST BUILD A SIMPLE DRILL/GIMSON POWERED PUSHER FIRST!
Even from a simple bot there are always lots of complications and you will learn a lot from building a simple bot. Just do a simple one first, even with an axe if you wish but don't over complicate your first bot or you will fail and have no more money so give up roboteering.

Re: Graupner motors

its not that much harder than the gimson bot to make.
it sounds simple.
it can't be too hard.
even.if its not my first fw

cheap, does.anyone have any idea.how many c they might do

you are completely wrong there, that thing will be incrdeibly hard to build to the precision you are talking at.

I would say just build a simple bot and work up.....

Re: Graupner motors

your funeral mate.
think very, very carefully, you have been asking if things have been a good idea and have been told multiple times, by multiple people to do the same thing. these are people with large amounts of experiance. maybe its a good idea to listen? maybe what you are being told is what you should do?

you, think it sounds simple, and forgive me if i sound rude but you have never built anything bigger than an antweight and so you probably don't understand many of the difficultys and strains a Fw would go for.

right, last time i'll tell you to do the sensible thing. good luck with your super dooper rammer defyer of logic and good-idea-on-paper robot.

Re: Graupner motors

Please wake up to the advise everyone is giving

And second those batteries are AA size and 1.2v each ill leave you to have a think to why this isn't a wise choice

Re: Graupner motors

Tried to resist getting involved with this but it was far too tempting.

I would urge you to listen to the advice that everyone has given you- most of them have built their own robots and know just how difficult it is.

For a first robot go for a simple 4WD pusher using either drills or Gimson motors- it will work and is a great way to learn about building robots. I started (many years ago now) with Whirlpool which was exactly that- it was very reliable and ran in its various forms until 2010. Since then we have built 18 other feathers which have all fought and hopefully got a little better each time (with a couple of exceptions )

I will repeat what everyone else is saying so start simple and work your way up! You will learn loads more by doing it that way and will not waste loads of money on ideas that won't work.

So my advice is:
1. Keep the idea simple
2. Build the simple robot
3. Get to an event meet people and learn from the experience
4. Build on what you learn from fighting your first robot
5 Enjoy it!

Re: Graupner motors

sorry for that.
i just struggled to realise what is so hard with wiring a roboteq to motors and batteries assemble your gears
plug in your rx
build the armour
sounds simple but if everyone advises not to then who have i got to blame when it dosent work.
on another note, do you recon it would be easier if ewan could build a gimson with a rs775 in it
that would kind of be a gimson
thanks for the advice anyway guys i think i.should follow you

Re: Graupner motors

You need to understand how much more time consuming and complicated it is to build a featherweight than an antweight.

I'll back up everything Will has said and I certainly agree with all the advice he has given you. There is nothing to say that you won't be able to build a more powerful robot in the future, but it would be a good idea to gain some experience beforehand.

I'd say get your hands on some good, reliable drill motors (preferably dewalts or something similar) and use that as your drive. This is the basic setup we've used in Annihilation and that's been running since 2007, fairly successfully and has recently been performing even better with the new A123 cells. Just because something is simple does not mean that it won't work well. We haven't even taken the drills out the cases, and they're only held down by two straps of rubber. Pick the right parts (not always the most expensive ones), build it reliably, keep it simple and drive it well and it should do fairly well.

Another matter is that the robot is not the only aspect of winning. It is also important to be able to drive your robot well, which I can see as rather challenging with a lightning-quick pusher, Explosion is bad enough! Building a simple pusher does not necessarily stop you from winning, as many have proven before.

Good luck and have fun.

Re: Graupner motors

ok I'm starting to get a build simple.idea.
can i use servos to move the switches on the drills instead of escs?
a simple wedge hopefully built for super cheap because then i will have no money for my next fw
thanks guys for this
and does anyone have any stuff i could use in my robot?
i will get to some car boots and build a kind.of little bitza.

Re: Graupner motors

do it propperly, then you can recycle parts.
no, you can't use drill electronics for anything other than paperweights tbh

Re: Graupner motors

Not really advised as it won't failsafe. Even using an external pair of switches and servo the way Rover does doesn't failsafe. ESCs can be purchased very cheaply anyway and you can always just transfer it to your other robot when you build it if you buy a good one.

Re: Graupner motors

the £15 ones.from eBay might do right.
my mum will let me get that roboteq esc for sale if i build a fw corkscrew replica because she liked it

Re: Graupner motors

You mean vantec, not roboteq. Very different speed controllers.

Don't bother. That vantec is not suitable for a featherweight as it's oversized and relatively heavy. That's why it was in a heavyweight.

Scrap the stupid ideas about crazy pushers and build a bloody simple rammer

Re: Graupner motors

if only there was a like button on this forum.....

I'm backing will, gary and michael up on this one.

Stop blubbering on about a super robot, and be sensible look through some old threads and build a little rammer!!
