Ok, thanks all, I'm sadly going on a family trip (NOOOOOOO) right when things start getting interesting. So, I'll probably loose inspiration since I've only just got started.
So, see you in about 4 days :x
EDIT: Wait, this is basically the robot I'd be building, only, mine would be smaller and more compact allowing for thicker armour. http://www.roamingrobots.co.uk/?pages=robot&id=1049
I'd hope for mine to be a little faster too.
Hi there
welcome
i like it how everyone has over looked a good building material.....wood
block of wood one of the cheapest bots, but it can take most abuse in 2007 it came 4th at uk champs against spinners
however this isn't a challenge for the spinner people :P
also go for plastic as top armour...much more entertaining for some of us :twisted:
alex
Lol.
Wood.
Maybe... :lol: Still like metal though :D
dont knock wood hehe , I have found that mdf has similar properties to hdpe , obviusly hdpe is stronger , but mdf has done me proud :) It took a head on hit from battleaxe's hammer and was still intact :)(same couldnt be said for the rest of the bot)
A good design also adds strength such as supporting the armour in its middle so it can't bend as much etc.
I point you in the direction of the RioBotz tutorial:
http://www.fightingrobots.co.uk/foru...utorial#p90784 - the forum topic is here
http://www.riobotz.com.br/en/tutorial.html - download from here
It's long but ruddy good and has a lot on minimum weight building (very useful), the calculations behind things (even more useful) and also data on materials etc.
Ok, well, I'm back from that family trip like thing and ofcourse, I no longer have any inspiration and I feel asthough I'm crazy to believe I could build a robot.
:evil:
Btw, downloading that tut now, and wow, it IS long! :o
That's some light reading for me :)
It's more of a book than a tutorial. I think it's marginally better than build your own combat robot which costs money :angry: (although it's still a good book to have.)
Ok...
After watching feather and lightweight rumbles and regular fights. I don't see all that many bots getting flipped, now, I know that's a silly thought, but making something that can run both ways up is highly restricting.
So, I've had a change of heart:
Still going for high speed and maneuverability, and if I can, good ramming power, I'd LIKE to build a hammer or axe-bot (whatever they call them, a robot with an axe, basically).
Basic design would be...
A fairly basic box, with a slightly raised and curved top, sloping maybe slightly curved sides and rear, a strong small scoop running the width of the robot at the front as low down as possible, preferably with no ground clearence (still hoping to be able to shove if needed :D ) and a huge, high speed, NICE and sharp axe on top, powered by a motor of some sort.
My brain is going crazy with designs but this one stood out to me, and y'never know, by putting Turn me over and fight like a man on the bottom (IF the axe for whatever reason doesn't work as a SRiMech) might get a few to turn me back over, if I got stuck! :wink:
It would be a struggle getting inside 13.6kg but I don't think it's impossible... Maybe I could laminate the armour... Suggestions?
Oh, and, obviously, name would be changed xD, suggestions there too please.

EDIT: Wait, how can I change the title of the topic?!
What about an invertible hammer?

To better push things you could put a scoop on the front to get under other robots (with a gap in the middle for the hammer to pass through.
In my mind something a bit like this (http://robot-club.com/teamtoad/halfpipe.html) with the slot and a hammer.
Finally, if the gear ratio was correct then a crude lifting fork thing could be exchanged for the hammer providing another option for different opponents (i.e. lifter for pushers so you can remove their traction and the hammer where you need agression)
Thing is realistically you'd want access to a machine shop or at least a lot of money (to get parts made) in order to do a decent axe. If you want real power in it, you'll be looking at running pneumatics as well, which require a fair bit of effort. You'd probably want to do a rack and pinion system, which is pretty simple and lightweight - http://news.terrorhurtz.com/axe/default.htm has a good overview of how a successful one (in Terrorhurtz) works and some drawings.
