Quick question for the people working on this- If I get it done in time, do you want detailed pics of my new 30 for replica purposes? (either as an additional real bot or to replace ruiner)

Decided to fit a few of the components in the assembly.

A lot of the pieces are end-tapped, and I don't feel comfortable going under 1/4" al. for those pieces. Just did a bit more work, chassis's down to 3.90lbs

Weight is down to 4.02lbs. Short of pocketing out the garolite, I'm running out of ideas for weight reduction.
Edit: Outdated.
Yes, I keep replacing the same image file on my server.

http://www.combots.net/wiki/index.php/GaroliteGarolite is a high performance type of fiberglass, composed of woven glass cloth in an epoxy resin media. Physical properties are similar to carbon fiber composite, although not as strong or stiff. It is much less expensive than carbon fiber and is easier to cut and form.
Garolite is not electrically conductive and does not block radio signals.

Chassis's down to 4.1lbs, green stuff is garolite, beyond that, just a decent bit of material removal.

Ordered 3 6 cell A123 packs for Mr. Self Destruct from Battlepack.com
Have:
Magmotor
Mag gearbox
Weapon bar
Speed Controllers(should get a spare or two, though)
Wire
Power switches(remake?)
Rx/Tx
Wheels(3 hubs not in use and tons of colsons)
On the way:
Dewalt drive motors
main batteries
Need:
Chassis
rx batt/bec
That should cover it unless I'm forgetting something.

looks like it might have trouble handling the stress of the application. I'd need to look into it a lot closer to find out though, and as it is, I've got my whyachi-box that's holding up quite well.

Just ordered 4 Team Delta 18v dewalt drive kits, giving me two full sets.

Took Apollyon to the tunnels under RIT for some driving practice. I now have a rather torn up cardboard box that was used for target practice and a fair bit of dust on the bot. Gave it a fair bit of hard driving, well over 3min including lots of full stop to full speed runs, hard turns, sudden reversing and general abuse. Motors were cool enough to touch and the a123 pack was cooler.
Notable increases in acceleration and and general responsiveness over the old battery packs.

Looks good. Love the colors, too.

Solidworks claims this will weight 4.41lbs as shown
Edit:Image outdated
Some more room to cut weight.
Edited to adjust weight totals for most recent render.
Switching the front plates from Al. to HDPE saves .36lbs, switching the front sides gets another .12lbs

I don't notice much of a difference between 1b and 1c, but I think that they are the best design. The back part of the central portion is different, and the sides are moved forward.

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.

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.

Here's an older 30 concept that's not in the running currently. Looks cool for a wedge/plowbot, but I want to build something with an active weapon.  The gearing in the render would give it a top speed around 20mph

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.

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

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.
