In the past we just mixed up everyone as trying to get battles where every opponent was different is difficult enough let alone making sure seeds don't meet each other. I will have a look into it though. It may be that seeds get 2 battle split and 2 none split.
Are sign ups full? And if so can we get a list?
What about we start a European ranking in FW class? Same points of UK championship could count to final ranking. A absolute ranking could exist since we have oficial information and last 5 yeas ranking, last 3 years and last year ranking.
How are the sign ups looking James/Grant?
When can we expect to see the draw?
Well the draws are normally left until quite late in proceedings to allow for drop outs or last minute entries / substitutions. The entry list may as well go up when there's enough to run the contest.
Need a hotel thurs fri sat .... any ideas wheres everone staying ???
We're staying at the Castle Bromich Inn. Fair price and good food right next door. Only a 5 or 10 minute drive to the NEC as well :)
we went for the sheldon travel lodge it was a good price when we booked bit its gone up a fair bit since then and its just sort of 4 miles from the nec
I'm in the Birmingham airport etap/ibis budget, seems dirt cheap compared to everywhere else I looked, and appears to be just a short walk away from the NEC, according to their site and the maps they've put up...
There's a reason Ibis are dirt cheap...
For last 2 years i stayed on IBIS airport, nothing to complain.
Obvious we cant expect a 5* hotel, but to just sleep and take a shower its the best you can get for that price. Clean room, tv with a few channels, paid internet.
The best way to NEC is across train station, take the shuttle from airport to station and walk to NEC, you have indications. Will find a "gate" where you need of show your pass.
Last and only time I slept in an Ibis at Gatwick, the bed was like sleeping on concrete!
Sign ups will be closed this Friday! Any last min entries please get them in quickly. The draw will then take place live on the Robo Challenge Facebook page on Monday 31st March :)
How many entries so far? At least 40 (80% of the planned 50), but how far off the total are we?
So I was looking at last year's videos and realised I don't have a strategy for axe-bots. Does anyone have an opinion on how thick a titanium plate would be needed to withstand the nastiest axe?
Binky was hit full force my Little Hitter and its 2mm Grade 2 Titanium got dented but no were near punctured. Conker 3 had 3.6mm of Grade 5 Titanium on the top. That should stop everything. The only worry is Grant's new axe machine that can in theory go through 4mm of Grade 5 but I doubt that it will actually be able to put all its power down to make that a reality.
All that said, Carnicus has, i think, 6mm HDPE top armour and it was fine. Bent but unpunctured and good to go again.
Realistically an axe robot isn't likely to do huge amounts of damage to the armour of your machine. 2mm ti would be fine to stop it getting punctured. It's the shocks that I hope will cause the damage :) (most of my axe heads will be blunt).
Our machine took several hits from LH3 (pneumatic axe, powerful) with just 6mm HDPE top armour, and had no issues, only chiseled the plastic a little. Hence this year I am using 5mm HDPE!
(I expect it to get quite badly damaged and am just going to have try and out-drive the opponent)
Hi,
I can say with all words what is fight against an axebot LH2 and LH3 :)
I use 5mm Aluminium 5083 and yes, it makes damages!! Never made "holes" on top, but left serious hits... ATM i'm in a 1-1 against LH, first time he hit the top and the ESC out of their place, entered on drum and obviously, destroyed ESC.
Last year i fixed the problem of the ESC, had a 3min fight against LH he completly discharged the air on top of Galactus, i won for points.
I can advise you (like grant said), if you use a minimun thick plate on top, dont worry about "internal" damages. HOLD all pieces inside and IF you can, to reduce "stress" on shafts of drivetrain use something underneath your robot lilke a "chock", so when he hit your top the "pressure" is dissipated to ground across the chock.
Im not worried about axebots, im worried with this:
Attachment 4420
Thanks guys; I have 3mm polycarb on the top of Mr Mangle but with some messing about I can make a 2mm Ti panel just for axe bots.
Just make sure you declare that at the weigh in.
BTW: 8mm thick steel lid on Satanix, minor nick marks from LH and Tinyhurtz :). I did find out either 720 or Drumroll managed to bend a corner when it hit the top horns..
6mm HDPE on Hell's Angel took the blows, plenty of deep cuts but none went through. HDPE is lighter and cheaper than polycarb, something to bear in mind.
LH3's pointy Axe head penetrated about 8mm deep into Splniter's 10mm Polycarb and blew clean through the 2mm Stainless I had on BitzaWood.
How the armour is mounted is crucial, as is how well your robot can take the shocks.
I'm with Dave, 8mm HDPE lid on Ricochet has a few cuts from TinyHurtz, a couple of dents from Major Damage, and surprisingly nothing from the hits from LH3 :/
Hmm, I might be in a spot of bother with 2.5mm Stainless then, if it manages to get a good hit and damages my motors. Tempted to have a removable lid for axes, made of 20mm HDPE or something. Means I'll no longer be invertible, but against an axe I'm not entirely sure that's such a big deal. Of course, if I get put in a first round battle with an axe and a flipper, that's a whole different story...
Tiny Hurtz didn't get thru my 1mm steel armour but rattled wires out of the speedo. You'll get dents from the big hammers but you'd be unlucky if they got thru. Gaffa tape your connections and give yourself a bit of air gap and you'll be reet :)
As it turns out, all my spare titanium sheet is too thick & heavy to use - might have to go with UMHW or just double up the polycarb for axe bot matches.
The air gap is the bit I'm worried about! My robot is super compact, and I'm not sure there's a lot of distance between the lid and the motors. Makes for an incredibly solid design but if an axe just manages to puncture it and get at something important, that's me done! I highly doubt that it will, but obviously I'm thinking of the absolute worst case scenarios and it gets that 'perfect' hit in!Quote:

I'll just stick some 3mm hdpe on top of 720 to take a bit of the shock out... Looking forward to the draw now!
How big were the bolts holding those armour panels on? 6mm or 8mm? I am still a little worried about the back of C3 as it only has 2 M8 bolts holding the armour on at the rear (Per side). Though there are not many Horizontals anymore.Quote:

Sorry for the noob question: how is the annihilator run? Is it optional, run after or before the main rounds, how do I sign up for it?
Annihilator is optional yes, usually run after the first round is complete and one or two of each type of robot is picked to enter. Normally 6 robots.

OK, Thanks for the info.
Hi Alex,
On impact 7x M6 12.9 was cutted like butter lol
4 on sides and 3 that was holding gearbox. Plus 2 bent M6 on botton, but i need to agree that was because the horrible desing and not just because NST hit.
No joking, im sure that if a vertical or drum robot (Bink p.e :) ) hit the rear of C3, will hit the roof of arena.
I'm worried about basically the entirety of Rango. The design is far less chunky looking in real life than in CAD. If I envisage a massive hit, basically anywhere on it, it doesn't lend itself to standing up. The design is as much a building exercise (tried to cram a wide range of stuff that needs making) as it is a solid box to take the hits. Just hoping, if it's at all reliable, that I can combine the small drum and speedy drive and control the fight. Of course in reality that never works with a massive spinner in the ring!
Maybe I'll trust it more once wedge is on. The hardox plate should seriously stiffen up the whole chassis.
I'm still unclear, are this year's qualifiers 1v1 or a 3 way melee like previous years?
My assumption was 1v1 but would like to know for sure.
That would mean 3 way melees.Quote:
