Snappy Robots
« on: June 13, 2014, 04:27:28 AM »
Yeah I don't have a team name so deal with that thread title.
Making all the threads everywhere now my beetle is getting a little more serious.

Initial Sketchup Model (Thanks Tweedy :D)


Current component layout - missing mixer, wheels and forks. Lots of wire shortening to do.


Current Cardboard Mockup (cardboard bots revival 2014)


Will be invertible. Front plate 3mm steel, baseplate/top plate/sloped sides 4mm hdpe, then the rest of the chassis 'box' inside the side skirts (back and sides) will be 10mm hdpe.

Static wedge or are they on hinges like Satanix?

Looks like they're servo powered lifters.

you sure that's a good enough lipo? it seems too big for a beetle.

Yeah the lipo's a little big, but if he has weight for it, why not? Not having to charge as often can be a lifesaver.

I crosschecked all my components with Tweedy and Haz so I'm pretty sure everything's alright.

battery is huge. you would probably be able to go a whole event without recharging with it.

something to consider: your lifter takes weight off your robots drive wheels when it lifts. I'm not sure if there's really anything you can do with your current design to change that beyond mount everything as close to the wheels as possible.


good luck with the build.

Oh yeah what wheels are you going for? Lite flites, banebots or something else?

If I have any weight left over I may look at the viability of some structure to help keep the wheels on the ground but we'll see how it goes.
Wheel-wise, I haven't actually looked into it yet, not entirely sure what the UK guys tend to use.

i'd recommend a lite flite or foam wheel over a hard rubber one for small bots because they absorb shock better so you're less likely to snap that tiny 4mm shaft or detooth gears.

I was thinking about foam wheels, so it's good to get some confirmation there.

Lite Flites are the best way to go, they're super light weight and get good traction, and are dirt cheap to boot. Only downside is that they need custom hubs, but the finger tech snap hubs work great.

yeah the snap hubs work fantastically for the 1000rpm motors. Just make sure to get the 4mm bore and not the 3mm bore, I screwed that up when ordering them for FireArrow. :P

Current Cardboard Mockup (cardboard bots revival 2014)
(Image removed from quote.)

"And, in the blue square, CARDOARD BOX!" :dumb)

But in all seriousness, (or lack thereof), this looks like it can turn out really good.
Strong, compact design, a bit generic but good nonetheless.

Apart from wheel-holes, wheels, wiring and assembly, it's almost done now.

Pretty happy with how it's coming along. Will be smoothing out those HDPE ridges at the front at some point.

It makes me happy when I see people build robots in real life, because it means that our sport will not be dying anytime soon.

The front armour and the flipping plate (yeah, I didn't have enough room for forks - or I did and this would be stronger, rather) are all 3mm mild steel.

Ran out of time with regards to mounting the steel and flipper as I had SO much to do without realising, so seem as though there aren't really going to be any 'battles' for Beetles as such at Bluewater this weekend with no arena, I mounted a temporary HDPE front plate.
The link isn't even in yet so the front plate hinges for me to get to the battery connector.
For the first time it properly battles, the steel and flipper will be mounted, and hopefully it'll run inverted (the wheels are too small on this iteration)



PS: Roboteers make robots look waaaay too simple

PPS: This thing has the ability to push shoes. Get a load of that.
