That's surprisingly cheap. I thought it would be around a hundred or so.

Once the new A123 packs show up and get installed it'll be ready to fight. Might toss on a logo sticker. You can see where one was, but it started to stretch so I removed it.

Looks real good.

Dang, now I need to update the Apollyon replica in DSL.

Oh well, I can update it to be better. Like that version probably is.

The new front end should take quite a bit more of a beating and it'll be a bit more powerful, I suspect. Higher output batteries should let it take better advantage of the power levels the mini-ev's are capable of.

Old wedge- .9375" thick steel with the leading edge heat treated covering half the height of the front of the bot, then 1/8" aluminum under that

New wedge- .90" thick 4130 treated uniformly to HRC 35-40, covering the entire front of the bot.

Old batts: 1650mah NiMH packs
New batts: 2300mah A123, 70A continuous, 120A 10sec. discharge rating.

Decided to start playing around with some concepts for a 30lber, so I'll be doing some preliminary Rhino models in the near future. When I decide to build, it'll either be a 30lber or rebuilding Ruiner, depending on what competition(s) I expect to attend.

Also picked up a Hobart Handler 135 recently and plan on learning to weld. 1st project is going to be an overly complicated welding table/part jig

Kinda reminds me of my awefull bot in BBEANS4.

EDIT: Just realised that looks like an insult but that bot looks good, real life is alot different to DSL

Heh, no worries. 'new' coke looks a lot like coca cola classic, after all.

They look similar, but one isn't as good as the other.

Starting on the 30lb concepts-

Concept 1a:

Model shows the same weapon as on Ruiner, but the bar could be shrunk a bit to save a few lbs. 2 2300mah 6cell A123's weighing approx. .95lbs each replace the 2 4lb 24v NiCad packs in Ruiner. Slightly lower voltage and capacity for a massive weight drop.

Wire routing WILL be a pain, but it should be doable. Making weight will be harder, especially if I don't swap out for a lighter bar. Luckily I could easily have a 3/8" bar made in the same dim's and cut it down to 7.5lbs.

Concept 1b:

It looks sorta like the illegitimate lovechild of 2EZ and Totally Offensive. Shaved a bit of weight/space out of Concept 1. Should allow less material to be removed from the central structure, or allow a bigger weapon bar.

Concept 1c:

Even further chassis reductions. Likely on the edge of stability if not past it.

Concept 2:

Concept isn't quite done yet. a bit tighter overall and lots of places to take weight out of without losing strength. Modeled with a 20x3x.5" bar.

Apollyon-
Doing some minor rewiring to fit the A123 pack in properly. I've got .5" between the motor at the back and where the pack contacts the front of the chassis, so it'll be a tight squeeze.

I like concept1 better than concept2, it just has a wider range of attack

kill343gs · « **Reply #113 on:** February 03, 2009, 11:23:04 PM »

I would go with 1b, it looks like the happy medium between hard to do and too weak. Concept 2 I would be worried about the weapon motor's chain so i wouldn't bother trying.

zipdragon64 · « **Reply #114 on:** February 04, 2009, 06:03:54 AM »

i would go with 1b-1c ish for the sake of it would be easyer to machine and i like concept 2 looks like a good solied hor spinner just needs to be invertible no point to losing a match because you just got fliped or something

MikeNCR · « **Reply #115 on:** February 04, 2009, 09:27:52 AM »

Placeholder name for the 30lber is Mr. Self Destruct.

Two reasons, 1, it's somewhat likely to blow itself to pieces, 2, Ruiner, which is being scavenged for some of the parts, was named after a NIN song. Figure I'll continue the tradition of naming Spinners/Weaponed bots after NIN songs.

Naryar · « **Reply #116 on:** February 04, 2009, 09:34:58 AM »

I do agree with ZD64. You could use N°2 (Tombstone) and use bigger wheels/flatten all the bot to make it invertible.

MikeNCR · « **Reply #117 on:** February 04, 2009, 09:38:54 AM »

Main issue there is the mag is 4" long, so I'd need 6" wheels to get proper clearance to get it invertible unless I built/bought another mag gearbox, and I'd still need 5" wheels to make that work. Still working on that design, but I may not get it to where I'd want it to be willing to build it.

hmm you know what i may have something that you may be able to use i'll see about getting a pic and some specs of it up for you, it converts a rotational input to a 90 degree angle its compact and solied but not sure if its strong enought to handel that kind of stress
