Speed controller and component locations

[jannas_gutiere]

Ok, try not to hiss and spit at me when I say this but due Im unsure of how to locate the components around my robot.

After much thought and a little help from an engineering lecturer I know, It was decided that alot of the comptonents like: Batteries, Motor, Speed controller and RC receiver could be mounted inside the wheels since the axle would revolve with the wheels.

Provided I make the wheels large enough to hold this, is this feasable?

Last question, which proves my somewhat lack of engineering prowess, can a speed controller like a Sidewinder limit forward and backwards drive?

Hope you can pull through for me again,

On motors, batteries and speedos. First of all, they wont come cheap if you buy new.

One stop shop for the starting roboteer is http://www.technobots.co.ukwww.technobots.co.uk

Paul Cooper is a roboteer ,and knows exactly what you can use.

What we (team RCC) use. Sidewinder speedos are very much the favorite in the heavies. Affordable, small and powerfull enough for a normal drivetrain.

Spectrum 2.4GHz RX/TX with of course the BR6000 robot wars specific reciever.

3700mAh NiMH GP 12V batterypacks

Motors, we used Bosch 750s, starter motors littons and the AEG Bosch 750 equivalent. But now were building an experimental drive....

Wheelsize. I did build 2 drivetrains were the Bosch 750motor was in the wheel. And the wheel was only 200mm outside diameter. So, its possible.

Thanks but would it be possible to cram all those components in the wheels because I was thinking seperate RC receivers in each wheel because I wanted tank control.

A similar concept http://www.cgcu.net/robotwars/?page=constructionhttp://www.cgcu.net/robotwars/?page=construction

Two seperate controllers rather than the Sidewinder ...perhaps one of the Victor range?

The Spektrum 2.4GHz RX/TX with two BR6000 receivers.

Stinger did it. So I dont see any reason why it isnt possible.

And 2 recievers on 1 spectrum transmitter, no problem. Just bind then together. Binding means radioconnected to your transmitter.
For conventional RX/TX sets you can do this by using the same crystals in the 2 recievers.

You could buy Real Robots Magazines 26,27 and 28 via Ebay........ These contain an article on Stinger and its construction.

I might be able to scan the pics in as i still have the magazine , ill try and find it for you Jannas

Brilliant! I could not have asked for more. Thank you very much!

did you collect all the magazines alistair? i did but glad i didnt pay for it- massive cost at the end of it all

This may seem like a wrong question to ask at this time but how do I stop the wheel motors from turning the axle since all the components are inside the wheels and the axle is allowed to turn so that the weapon may swing over like Stinger. Im very sorry but I cannot find many information on the internet since the tv show ended a few years ago.

Heres a Stinger like ...Feather Axe bot.

Jannas could you supply some information on yourself ...... Engineering experience ....Access to a machine shop ... Budget..etc

Engineering experience: I am a novice to engineering but I am studying Mechatronic engineering in scotland, I have little experience apart from making tools. I have access to a full machineshop should I need it and budget maximum is £3000 pounds.

Anything else you would like to know?

where abouts in scotland?

there are a couple of us up this way!

Inside leg measurement , hat size and weekly booze consumption....

I believe that the Weapon provides a stop to prevent the axle rotating ...the wheels torque reaction is transfered thru the weapon and onto the ground thus allowing drive.... reverse the motors and the weapon / axle performs an overhead arc.

If you have any questions about the feather axe-bot (deBiel) you can send me an e-mail. I can tell you that a lack of traction does not prevent the axe from smashing backward and forward. This is simply newton doing its job, the mass of the wheels with the motors providing torque agains the mass of the axe.
I will be competing in the Thialf event on 22-24 June, adding rubber to add traction. I hope it has a dramatic effect, although hopefully not on my speedcontrollers
The forces involved are quite nasty.
