Sabretooth Reborn as a Feather

Well thats exactly what I want

then do it :)
a very different robot, very interesting indeed!

developing the interchangeable weapons, the drill i did today, a lot of dremmel work cutting down the body, the disc will be machined soon.

First picture looks like a mini-Warhead, minus the tail :)
Second picture puts the size of the robot into perspective, it looks tiny!

But all in all it's still the most interesting looking feather I've ever seen and can't wait to see how it progresses.

Love the tilted disc concept, as Gary said very evocative of Warhead. Are you planning on running the claws with steel cable so that as the bottom section moves the second outer section simultaneously unfurls? That's the first idea that comes to my mind

I know us Scots are few and far between in terms of robot combat, but is it that easy to get us mixed up? I drive a Kia Rio over a Peugeot RCZ for a start :lol:

Dang.. sorry about that Jamie, was on autopilot which seems to suggest my subconscious is 'Scottist'? I blame your robot's colours =p

Thanks for the comments Jamie and Ewan, and Gary if he shows :). Ewan you are spot on with the claws however I will do some testing and i have a single claw idea which may supersede the twin claw thing. I'm waiting for you Ewan to get the other actuators in then I will be making a large purchase of wire, actuators and some other bits and bobs. All the HDPE arrived today so its off to the workshop and out with the router (on a slow speed):) The dish-disc will be made in Canada, once I've completed the drawings.

PM sent re. actuators

large Gimson order placed, actuators, wire, deans etc
HDPE marked out
and got a sponsor who is purchasing me two sets of radio control gear - which is nice.
I will be working on the hdpe over the next couple of days, will post pics as they occur.

so Today, I have done precious little work, I have however completed the 600cc mini twin for Sunday and started on the bot - pics

with the Gimsons, got three so i could test the sizes, the bot is so tiny, its going to be a squeeze

I wish I could afford 3 of everything to test!

They will get used :)

Ha, just found the last incarnation of Sabretooth, that disc was driven by a 125cc engine 6500 revs

armour cardboard development

completed design lets hope it self rights

So guys run your eyes over this and give me feedback before I have it made. The idea will be to have a aluminium top and a steel rim. The bearing is pressed in and then the gear is bolted on the bottom.

the coolest spinners are 1 toothed spinners :P

One tooth? could be a problem with balance whilst in motion

have the steel rim go into the aluminium centre more on the opposite side of the tooth. on omen i have a section milled out of the tooth and surrounding area, this could be hard to implement on a rim style disc though.

So it will balance with the opposite tooth profile inside the rim? yes

Yeh

Really nice looking machine there!

You will need a bit more than just the equivalent tooth on the inside of the rim because although they would be the same mass, the inner tooth is closer to the pivot and so isnt balanced. Will need a little bit more. If you email me your drawing and dimensions Il produce a 3d cad version with the counter balance single tooth design. james(at)robochallenge.co.uk

Keep up the good work!

Thanks James I thought that would be the case, measurements emailed

so here are a few updates

and some more pics

and just because its fun, and i have a surplus of parts. I will be starting on another feather, with some exciting lifting bits, it will change shape during the bout

That's an unique looking machine, Im eager to see the weapon tests :)

more pics work is coming along :)

and more

Looking good Gabe. I like the slots you've got in the base for the bulkheads; combined with screwing/bolting them together, it should make for a very solid chassis.
Can't remember if I've asked this before, but are the two idle wheels friction-driven from the powered wheels, or do they just spin freely? It looks like friction drive in one of the pictures but not 100% sure.

Hi Jamie

I wanted all the parts to be able to interlock into each other, The non drive wheels will indeed be driven off a jockey wheel. the only way i could make the wheel base and the robot as small as it is.

it's so tiny!
awesome work 8)

the base measures 220x300 so quite small :)

another update, adding aluminium to the bulkheads

Thats really cool looking :)

so have been quiet for a bit, but heres some progress, i've been inspired by the self righting arm :)

Do you have any paintball bottles?

What size do you need ?
