Fractal [beetleweight]

Finally got round to finishing (or near enough) the beetleweight machine. Here's a few pictures.

Shown with a drill motor for an idea of scale.

And upside-down.

Finally here's a video.

It only weighs 760g currently, and as the drive is more than tough enough the rest of the weight is likely to go on even more armour (it's already got 3mm titanium on the scoop..) and a beefier lifting motor (currently lifts about 1kg at the end of the arm, which would be enough to tip a beetle over but carrying one would probably look more impressive).

Now just to wait to have somewhere to use it...

looks awesome

thats sooooooo cool

Lol, this really means I have to get mine done... just needs drilling and tapping a few holes and sorting out the weapon pulley/bushing deal now I think.

Looks great :)

its so good i would buy it if i was not building my own 1 :mrgreen:

A track bot yay :D

your my new friend lol :)

looking good. How much do beatles weigh again?

i thinks its 1.269kg

is 75g max

yes its 75g :shock: :shock: :shock: :shock:
NOT!!!!!!!!!!
THATS LESS THAN A ANT ROBOT
:mrgreen: :mrgreen: :mrgreen:

NO ITS MORE THAN A KG

thanks for comments! maximum is 3lb / 1.361kg, which gives this machine 600g to play with 0_0

haha i was nealy right :lol:
I WIN :proud:
(75G GOOD 1)

It looks great ewan, I'm liking the fact you're using Banebots, underated as small robot controller IMHO, I use them in 2 of my antweights.

BTW, FYI, 75g is a weight class limit, just but beetle, its the Fleaweight limit (next size robots down from Antweights)

Really looks like my antweight :D

woahh, talk about 'great minds'! have you got any video of that machine? I reckon the two robots I took most inspiration from were http://lazytoad.com/teamtoad/avalanche.html and http://www.irobot.com/gi/ground/510_PackBot , though now it just looks like I've copied you =p

Also wish I had the equipment to bend metal like that >.<

Its a good design all round, the weaker version with a carbon fibre scoop actually won AWS 31 :)

Really reminds me of the antweight Shazbot from Team Nightmare. Great job! :mrgreen:

I was planning a robot like that, but I might not build one like it now

Changed the arm-servo from the cheapo chinese one to a modified Hitec HS-7954SH. The previous one had stripped a few teeth so I'm hoping this one will be more up to the rather violent motion the arm goes through when 'somersaulting'.

What kind of motors do you use for that weightclass? And where did you get those tracks?

Tracks - http://osbots.com/shop/product/tank-tread-set/ (got a set of soft-rubber wheels too which are actually grippier but the tracks can climb over things.. and look cooler)
Motors - http://banebots.com/pc/MS-16XXX-050/MS-16038-050

You can of course use other motors though!

Thanks, was looking at some motors between the antweight class and drill motors as i wanna build something in between aswell as another project

Swapped out the 11.1v battery for a couple of 7.4's in series, it's very cramped in there but now goes a lot faster!

Still no beetleweight competitions...

if you had enough power in the lifter motors, add some spikes onto the scoop on the correct side then it could double upm as an axe :)

probably a crap idea but would look dam good :)

Any videos with the higher voltage and new arm servo running? I just love how the thing looks!
