Thanks Harry, the batteries and electronics all go in the middle square. But it is 80mm tall, so i hope it will all fit in. I will use steel for armour, then a layer of rubber, then a layer of 3mm plexiglass/perspex.http://i1280.photobucket.com/albums/...psc22819b2.png
will sure be impressive and compact if it works.
Sure its not too compact though?
I know you have read my thread about the sizes of featherweights but you might want it 1/2cm bigger in diameter.
because NSTs bar could easily damage those motors whick are soooo close to the sides.
Ok, thanks Archie. I will start programming my beetleweight this week. Here is a link to the controller board that i will use. It is only 20mm in diameter and only costs £5! It will need a programmer but Sparkfun also sell them. I will be ordering the wheels and motors soon, but first want to complete the beetleweight. More pictures of it after i have painted it. Do beetles need removable links or not?

botbitz are probably the best cheap controllers available but I have absolutley no idea about programming.
I basically edited everything I said so max dosn't make me sound like an idiot.
happy days and stick with max's advice :lol:
i cant even do smileys right today :rofl:
Your beetle weight motors will only draw a few amps so you should be fine- I think you will need either an H-bridge microchip or some mosfets to control your motors though. Your other option would be to make the microcontroller control a normal esc.
You will also have to reprogram the microcontroller bit it says that is possible. I assume you are able to put inputs on that microcontroller which you will need for reading the signal from the receiver and from your accelerometer.
sorry for this tiny thread hijack but on the note of programing ESC's.
Could I use an arduino microcontroller like this

To control a botbitz speed controller for an axe?
Thanks
Look up arduino as isp, never done it myself but should do what you want.
You don't need an arduino mega, an arduino UNO will do and is much cheaper (£10 at technobots) or you could use an arduino mini.
I am sure you could use it to control the axe with a botbitz, if you are good at programming then you could get some really nice features for your axe like an automatic slow speed return or some sort of rapid fire system.
Thanks for your answers and sorry marvin you can have your thread back now.
I will ask my questions in this thread http://www.fightingrobots.co.uk/foru...=5725&start=30
As promised, here are the pictures of my beetleweight robot. It doesn't have a pizza theme, but i had to use up the black paint i bought for it. Those stickers on the top are not sponsors, they are just showing what i made it with. The weapon bar will not be supported by zip-ties, that is just temporary.http://i1280.photobucket.com/albums/...psb4e5bcf1.jpghttp://i1280.photobucket.com/albums/...ps322052a3.jpghttp://i1280.photobucket.com/albums/...ps2b975dd7.jpg
