I'm still trying to get an E-Tek and the components for my weapon. Things have stalled out for a second time with this. It also turns out that my receiver is programmed to send small pulses when the receiver's battery is low (I don't have a BEC). I'll need to add an additional failsafe to stop that. Let's see what's left on the to-do list... Get batteries Already done.Get Speed Control for drive motors Already done.Preliminary wiring for test purposes Already done.- Find weapon motor and components
- Install power distribution circuit (Y harnesses, cutoff link, fuses and main power switch)
- Go to scrap yard in search of some still-useful plate metal for armour and some spiky bits for decoration
- Find another HW builder in the area for practice
- Enter first competition
My... that's a lot of things still left to do... On another note, I decided to also design (not build) a combat robot in a more light-hearted way - with LEGO components. People build combat robots out of these lightweight plastic construction toys surprisingly often, and I recommend it for people who just want to play around for cheap and can't commit resources towards a true combat robot.  This is Syclone. As you probably already know I am also a member of Rock Raiders United, and I designed this for their LEGO Creations section. I decided to design something similar to what is seen in the LEGO Robot Wars videos on Youtube. 4 XL Motors for drive, 1 for weapon, 2 battery boxes (pictured: 1 battery box version) and two IR controllers. Against a proper robot this thing would be a  , but compared to other LEGO robots it may perform like Tornado with its vertical spinning disc. Don't worry, I have no plans of designing a giant frame to keep the robot from being pitted...

you added space after every comma.
Which were in the stock bindings. Take a look in the bindings of a completely stock install of RA2. Even if they weren't there, everything worked on my end.

Here, fixed your bindings:

and your bot crashes my game (and possibly GRW's) for some reason, possibly the skinned parts,fix it.
never mind, it's one of those random crashes. I would tell you what's wrong with your bot, but it'll spoil your entry. post it in your Stock showcase.
I took a look through what you "fixed". I see no difference except the removal of spaces that can be found in the stock bindings.

Attached is my robot and bindings. I know it won't win, but at least I made it stable.

BackSlash, you lucky !@#$%^&! Every opponent it went up against immobilized itself or was caught up on top of an arena hazard.
I doubt it will make it any further though.

I'm interested in entering (even though I kinda dislike Stock). I'll send my bot in once I've ironed out the kinks.

To quote a certain Mr. Nostalgia Critic:
"I'm awesome." 
The reason I asked is because I'm having trouble with getting a Popup under opponents.

When I first saw it, I thought that Broken April was another SFTW.
Then I saw it beat not only Razer (though granted the replica isn't very good) but Firestorm as well. How did you make that good of a wedge without any wedge parts or skirts? I know for a fact that a wedge shaped chassis isn't enough to outwedge anything else...

Ring arena? Looks like I'll be entering this one.
EDIT: I can see why AGOD can be annoying...

Is Spinner from the West, the best and worst robot ever at the same time.

My lesson from this challenge: IRL Robots usually = At least I went out in style.

That's not quite an accurate reading of what I said.
For the sake of simplicity, let's pretend that the 24" drum has exactly twice the MOI of the 12" drum. We'll call them 1 and 2, since it doesn't really matter as energy is linear for MOI increases.
We'll say the big drum is at 2500rpm, little drum is at 5000rpm
5000rpm gives an angular velocity of 523.6 radians per second
2500rpm gives an angular velocity of 261.8 radians per second
So, for the 24" drum, you have (0.5)(2)(261.8^2), which is 68,539J
So, for the 12" drum, you have (0.5)(1)(523.6^2), which is 137,078J
Those numbers are way, way high, as the MOI would be lower in reality, but for illustrative purposes it works. This is why there's been a trend recently to spin a lighter single toothed disk/bar/etc at a much higher speed for spinning weapons.
That's what I get for not doing my math on the fly. My first and third reasons still stand, though.

The bigger it is the harder it hits right?
Rotational kinetic energy is 0.5*(moment of inertia)*(Angular Velocity^2)
What that means is doubling MOI doubles energy, doubling angular velocity quadruples energy. I'm personally a fan of the compact, dense drum geared for high rpm, but both have their benefits.
Exactly. My reasons for using a large drum rather than a small are three-fold. 1. It looks awesome. 2. As you said, 24" drum spinning at 1000 RPM has twice the power as a 12" drum spinning at 2000 RPM. This way I can take advantage of using a brushless motor designed for 1/5th scale RC car electric conversions (at least until I upgrade to a PERM PMG-132) without worrying about whether it can keep up the massive RPMs needed for an effective drum. 3. Smaller drums don't seem to have that killer uppercut I'm looking for.

Welll than that's one huge drum. Could make for some very impressive gyro dances
Indeed. I've seen an older video of Redrum, and it gyros like Nightmare or Sunshine Lolibot and behaves more like a VS than a drum. The drum will be further forward on my robot, though. I don't know how that would effect it, but I'm hoping it dampens the effect. a 24" drum is like twice the height of your average 220. sewer snake is only 8" high last rites is less 10" high.
Not everyone builds Biohazard-style low-to-the-ground robots. Also, a tall drum can still hit those machines.

Where does that compare to say RedRums
Similar size. It looks like Redrum has a 24" drum. Actually, part of my inspiration for the design in the first place was Redrum (the other part was an Ork Battlewagon from Warhammer 40,000, which with a Death Roller looks a lot like a giant version of Redrum crossed with a military half-track and covered with armour plates).

18 inches in diameter at the very least, if not 20.

At this rate might as well put every bot up there.
I think that would be overdoing it. Unless Alien Warrior 2 pulls off an upset in 2 Tribes, it shouldn't even get a mention.
