Fall-Out Bot (FW)
Well, with the retirement of Ricochet a new robot must take it's place, and since I still can't afford the stupid money needed for Titan Jr, I'm using the bits I have already for a competitive rammer with some interesting features.
First off, I already have the innards:

For those who don't know the specs, the drive is a pair of genuine Speed 900s in a Mario made, motor-in-wheel 7:1 gearbox. The wheels are 120mm diameter, 50mm wide with dirt bike tyre. Running the motors on 6S gives a top speed of 26mph, Skyfall was always too fast and hard to control, but that's how I liked it hence I decided against the gyro. Driven as ever by a pair of BotBitz 85A ESCs, the cheapest option for Speed 900s!
Design is so far an internal Hardox structure with 10mm HDPE bolted on, and an external Hardox frame:

The design is to have multiple bolt-on frames, each with different front ends. The two shown are the standard wedge and the anti-flipper (Beauty) spikes, designed mainly to take advantage of Beauty's open sides in order to ram it all over.
Another idea I had was that a beefy servo can be used to raise and lower a skid in the back, a bit like Dantomkia, so that it can push the front to the ground most of the time, but can allow it to raise up if needed, such as if the spikes get into raised areas of exposed armour (Beauty).
Thoughts :)?

looks like 720 and tiny toons brown love child… lol
-
It does actually... Good to know, they both work well! The brown is just to highlight the Hardox, it'll have a proper paintjob when done.
-
Looks good and nice and simple. Should be quite effective if driven well. Great CAD model too.
-
I need to learn how to render in sketch up!! The designs are looking quality by the way Jarvis, well done :)
-
Its as easy as piss.
Go to view, edge style and turn everything off, including edges. Then you can add shadows for added poshness.
-
Yeah, that doesn't look nearly as good as actually rendering in Sketchup ;)

I would turn the motors, and mount them on shock mounts on a spine.
-
Looks a very interesting design! Having multiple outer frames is definitely quite a novel idea, would like to see how that one pans out...
Just a suggestion, outer frame with a maller on it or something on one side? Would be a cool idea to have an interchangeable thwackbot attachment!
-
Seperated frames can work well.
I did an spaced frame with my rambot, Annoying Box Rushing (Built hastily in 3 Days) where the outer 5mm Hardox shell is suspended from the inner aluminium body via rubber shock mounts.

Thanks for the comments :)
Designed to be uber-simple and reliable, so I can still have a competitive machine that won't need that much fixing so I can spend more time fixing Flow at the champs. I like a good rammer, especially one that does silly speeds! Matt I might look into the thwackbot idea, a solid arm with a nice lump of tool steel on the end pivoted by the frame would make a mean impact.
Been doing some maths, weight with 3.2mm Hardox is 11.25kg for the bi-wedge frame and 11.45kg for the wedge. So weight is definitely not a worry :D. Could easily bump it up to 4mm, maybe even 5mm for the front of the wedge. Hoping to have this one done to run alongside Flow at Newcastle for the Northern Tour, should make for some fun fights.
