Terror Australis I & II Robot Wars PageIf you don't know what Robot Wars is, check out their web pages. There are similar competitions like Battlebots. Also have a look at Robot Combat Links.
In 1999 I (Peter) found out about Robot Wars through a Professor at our university. As soon as I had read the rules I was hooked... I had to be there. I managed to convince one person in the class I was teaching to help me (that was Rodney). I also convince Nick, a collegue of mine, to help (he didn't need much convincing). So, in June 1999 three unsuspecting guys (that's us - mugshots coming soon) by the names of Nick, Rodney and Peter (me) endeavoured to enter the International Robot Wars competition to be held in London later this year. We had some great design ideas which were mostly discarded due to their complexity and our sever time constraints (the filming was supposed to start at the end of August). We finally decided that the best way would be a petrol powered beast using a lawnmower engine....
To cut a long story short, here is the final result...
The robot is powered by a 4hp 160cc Victa lawnmower engine. It uses ring gears with cut down Mazda 323 rims as wheels. The rubber on the wheels are cut-down car tires. The chassis of the robot is welded from 20mm RHS steel. The covers are 1mm steel plate with the important areas covered by another 2mm steel plate or by 1mm thick aircraft titanium. The budget for this robot was basically 0 but it ended up costing about $400 to build (primarily do to the bearings in the transmission). The robot has the same steering as a bobcat. Each set of wheels (each side) can go forwards, backwards or stop.

More coming soon...
This is the robot we had to borrow from the Irish team (Thanks again)
Here are some webpages of the great teams we met while in the UK. If
you are not on this list it doesn't mean you weren't great people... I
just havn't got your web addresses :-)

an update?

e-mail Channel 9 and tell them that your interested in Robot Wars and
can't wait for the Australian competition to start
Here are some hints and tips that I/we will be using to build my next robot
Do NOT
use a petrol engine for driving. The advantages (like for power for
less fuel or batteries) are far less than any disadvantages (like noise,
dirt, grease). I would only use a petrol engine if I had access to
a well outfitted machine shop and could build/acquire a proper transmission
with a good clutch and good gears.
If you
use a microprocessor between your RC receiver and your servos/motors then
make sure it can decifer the servo pulses that are very noisy.
Make your
robot reliable! Do not cut corners. In the ring, there are
so many forces and things acting on your robot that anything dodgy that
you did will break. This will cost you the competition!
Don't be
too concerned with armour plating your whole robot. Weapons of other
robots such as axes or spikes are generally inaccurate and not particularly
powerful. Some axes out there are very good however. But you
have to make sacrifices somewhere on your robot to remain within the weight
limit. Armour plating that has some sort of impact resistance is
worthwhile, for example, two aluminium plates with hardwood in between.
Saws tend
to be ineffective and you have to worry about whether the saw blade is
tipped or not.
A lot of
the competition depends on your driving skill and how fast your robot can
manouver. However, this is no reason to put all your efforts into
the driving chassis of your robot and not into the weapon. An EFFECTIVE
weapon is VERY important.
Build your
robot so that it can either right itself after it has been flipped or run
upside down. A lot of robots are still becoming disabled because
they get flipped upside down (or out of the ring :-)
Do lots
of reading on other people's web pages. Most teams who have web pages
have a hints section such as this one.
Other things...
I'll add them as they come to mind
By the way, the background and the Terror Australis logo that is shown on this page is printed on one of our team T-shirts... just in case you were wondering.
