Team DD robots!

Hi there!

Short story of myself (TLDNR at bottom);

Ive been around this forum since 2004, now and then. Were in the old forum aswell until everyone moved here after the original robot wars ended.
I'm a swedish roboteer and since my interest for this hobby has spiked again (got many hobbies i rotate) I'm back for more.

Luckily I've gathered a decent pile of parts and its ever growing.
Nothing makes me more tempted to build than reading build diaries and pics of progress of other people's robots and I've seen a fair few mention the same thing lately so here's my contribution!


So after seeing tons of robot wars when younger and being the way I am I've always aimed to make really good robots even tho being my first ones. So after about 4-5 total rebuilds i finished my Antweight flipper named Bounce (unless its taken ofc).

And it currently looks like this:

Its made a while back but the specs are as follows:
General construction: 0.75mm macrolon (could be 0,5 or 1mm, cant remember)
Drive: 2 polulo HP motors
Esc: 2 botbitz EScheap 10amp
Flipper servo: HPX Park BB (something like that)
Battery: Gravity 250mAh 7,4v Lipo
Notes: 6V voltage regulator after the schematics someone on robotwars101 posted i believe

My other Ant is an attempt on a invertible tracked pushing robot, no name yet and I've only made the basics:

Same general macrolon + 5mm hdpe
Drive: Cheap chinese 50:1 motors
Scoop / wedge: 1mm titanium
Esc: Got 2 old botbitz EScheap 6amp but not sure yet, might go into my first Beetle

I did make an early version of a FW many many years ago but it's not alive anymore so I'm building a new and Improved one, sort of.
Learning from my mistake with the Ant to try and make a championship robot, this one might not even be a competitive robot at all! I will first and foremost use this as an starting platform to test weapons / learn to drive / break parts and replace / shovel snow? yeah you get where im going with this.

Anyways its going to be a 4wd one from cheap drills, we havn't got Argos here but the equivalent.
Not sure my 2x25A sabertooth will hold up for 4wd, and i do want to order a couple of the TZ85's but they're out of stock atm. Anyways heres the pic:

And seeing as Beetles seem to ahve become really popular of course I'm starting one aswell!
I was smart enough to buy 2 of the 1000rpm 12v motors a few years back and some other stuff:

And today my candy from hobbyking arrived aswell! :D

TLDNR: I've been here since way back, starting a few projects and making a new build diary to crit you with wall of texts like this ;)

Which speed controllers are you using for the beetle?

It will be either the botbitz 6amp ones or if i can get hold of new 6-10 amps once they're in stock again. But probably the currennt 6a ones as i will built the beetle before the tracked ant. Might use my sabretooth 2x10 for a 4wd beetle as a starting platform aswell seeing as the other beetle will be a spinner

Oh ok that's cool, been looking into a new speedo so wondered what people were using.

What awg wire would you guys recommend for the beetle 1000rpm motors?

I used 22awg in mine and it's held up ok but saw people with 14awg ish at the weekend.

Just use roughly the same sized wire that's already on the ESC.

Good points guys, cheers

What belts and pulley would you guys recommend for a beetle spinner setup? 4mm shaft on the motor, disc size not decided. Would the fingertech ones from robotmarketplace be any good or have you got other recommendations?
I dont have any access to a lathe or 3d printer myself either

3mm HTD if you're set on timing belts. Check out beltingonline.
