Graupner motors

[archie2000]

so i kneed 2 solenoids on.my axe motor, one to move it back the other to.move it forward.
sorry guys i.will do some more reaserch on this.
thanks Maddox

i found these that might be good
http://www.ecrater.co.uk/p/13109042/sol ... EQgwgwBDgK
so how could i control one of these?
eg like switching it on and off.
also how.much can i overvolt an axe motor cos i won't be running it for more than 1 second?
sorry for these noob questions
cheers

You will use EITHER a solenoid or motor to power the axe. But as Mario just pointed out a solenoid will not be powerful enough, so stick with using a motor.

It just so happens that a very small solenoid is a component of a relay - relays can potentially be used in controlling your axe and I think that's where your confusion lies.

ok thanks
after that i think it will be much simpler to.build a pusher.
not just any pusher, a superpowerful one.
how about 6xRS-775-18 drive on 24volt to give over 5horsepower.
i love the robots bonx and satanix and.my aim is to smash robots into the arena and crush them.
i have the money and determination and the ability to do a messed up CAD.
only issue is speed controllers,
6 electronize 30amps will take me back £250.
what's the cheapest speedos i could get hacked brushless to brushed?
i will use mod 1.5 technobots 17mm thick steel gears with a 4wd system.
could i have a larger wheel at the back and smaller wheels at the front all connected with bike chains?
thanks.

this should be interesting

I know its all good having 5 horsepower, but lets just think for a second, 1 = a featherweight will never be able to put that sort of power down and will just spin the wheels unless you use magnets ( only anygood at robo challenge event as there floor is metal), 2 = Weight 6 gearbox motors will weigh alot aswell as the batteries and speed controller needed to run them 3 = Very expensive,

Just think about cobalt runs 2 x rs550 (£7 motors) on a pair of banebot gearboxs and that has more than enough power to smash other robots around, also think about if you get under the other robot you can push it using bosch 35watts ( not needing all that power )

Look at what other people have done and decide what you want to do, a good drive train can be cheap if you pick the right parts

If thats you're only issue, then I applaud you.

Anything's possible, but no. That would be making life needlessly difficult for yourself.

Why?


I'll put forward a suggestion to you on something that will actually work, and won't cost you millions and millions of pounds and hours of questioning people about various designs and you can see what you think, similar to what Kenny has done.

Why don't you get 2 speed 900's (or clones) and the Vantec Jonno is selling (60A per channel if I remember right and much, much cheaper than 250 bucks of electronize and make a 2, 4 or even 6 WD that are all the same size (or as many wheels as you want for that matter) system that uses standard-ish components, has been done before and might actually work? That way you have a pretty powerful machine that is pretty similar to Satanix and Bonx as you mentioned?

[archie2000]

hmm all that has been done.
and so far i don't know many robots that can smash a robot to.bits by driving into it.
how about i go for the speed900s on 36volts?
sorry for these questions but if i never say anything there is that small possibility it might work.
is there anyway i could get a bot 1 up from bonx?
thanks anyway

[Anttazz]

That depends on how well built the other bot is.

Interesting that you say no you dont want my design idea and suggest a design that is identical to the one I just said in every way but adding the 36v in, something that I didnt even mention. They do work on 36v though. I think they're up to 40v max so should work. What sort of current that would draw I dont know, but what I do think is that, like Kenny said, you'll struggle to get that power down.

[archie2000]

how about 4 of the rs775s overvolted, grippy wheels, 4wd?
that would be a contender wouldn't it
kind of sensible
