Really awesome :D Love how it can do the little left-right, left-right jabs with the two spinners!
Cant wait to see the results of the upgrade

Hi,

How have you made that linkage to connect the axe to the two N20 shafts?

Is it some kind of shaft coupler, flange plate thingy? Did you machine it yourself? It looks good anyway.

That's a pair of Pololu universal mounting hubs...

I drilled out the 4 threaded holes in one of the hubs, and countersunk those holes. I then ran bolts through the drilled out hub, through the axe arm, and screwed them into the second hub. The hubs then attach to the n20 shafts in the usual manner.

AWS 58

Well, AWS 58 proved very successful for Team Zero, and much to my surprise I’m now an AWS winner!

Six months ago RBMK was no more than a mad idea in my head that I was less than 50% sure would even work at all, and now it’s the champion of an event that is normally dominated by wedges, flippers, and the occasional vertical spinner. Honestly I still can’t quite believe it.

It had a great run, dishing out plenty of damage along the way (hey Dominus), but it wasn’t all smooth sailing. During it’s group fight against Error.3xe it sustained damage to one of its main spinner motors, which meant that for the rest of the event it struggled to move normally, and in the first fight of the final Trigger broke both the small vertical spinners. By the last fight it was barely working at all. I don’t really remember the final but I think it was fairly even, with both bots taking damage, but in the end RBMK kept going and managed to hang in there just long enough to take the title. Hooray!

Valkyrie and Zero also had a good tournament, Zero picked up a standard 3 wins, including one that must have been over in 2 seconds flat. Valkyrie has a great event, winning it’s group, and going undefeated (not including a nominated loss against RBMK) until being eliminated by Trigger in the third place fight.

A great event by Chris again, with lots of excellent bots, my particular favourite was Dave Weston’s new drum spinner Baphomet, I’m just glad I didn’t have to face it.

Already looking forward to attempting to defend the title in Sheffield!

That is a brilliant robot and probably the most original but not quite the first walker to win an AWS.
Mutant won in 2004 at AWS15 but there were far less robots to beat back then

Congratulations on your performance at AWS58! RBMK's journey to the top was spectacular to watch.

I stand corrected, someone told me it was the first, but I guess they don't have quite your level of aws knowledge (I'm not sure anybody does to be fair)

Quick pre-AWS update, and the main news is a new chassis for Vampire...

Image

The old one was looking a bit worse for wear (I counted over 60 hits on the armour!), and there were a couple of issues I wanted to address. The new chassis is wider and lower, this allows it more space for a bigger battery, and extra clearance beneath the bar to stop it hitting the lid. At some point soon I hope to give it a new longer bar, but I'm waiting on some new smaller/lighter drive motors to arrive (goodbye N20s, hello N10s :D)

The rest of the team have been repaired but are basically unchanged, the previously mentioned new version of RBMK is currently on hold as I can hardly replace a reigning champion!

Looking forward to Sheffield, it should be great!

Nice neat name logo in the side :D Is it CNC milled in? A stencil? Transfer?
Looking awesome as always!

Cheers, it's done as a toner transfer. You print the name (reversed) using a laser printer, then iron it on to the metal, and finally soak off the paper.

I originally learnt the technique as part of producing homemade pcbs, and realised the transfer part of the process (without any etching) would make a good way of labelling metal boxes (when not building robots I also make my own guitar effects pedals).
