i thought it was right to name this robot "Chaotic Tendencies" after the amount of trouble its caused and strange behaviour its shown but all seems to be in working order..
the translation is still poor but it shows movement.. wont be to many dodge moves haha..
Took it to work this week to test it out on the workshop floor with heaps of room to move.. threw some stuff into it and watched it fling objects across the workshop.. seems to hit pretty darn hard.

Was trying to get some bis teeth cut out on the plasma at work but its not finely tuned enough atm to cut such thick material.. its only a prototype after all..
so went with 4 layers of 3mm Stainless which should be good enough.

a photo of the shiney new tooth nom..


some damage.. this was only with a 4mm mild steel tooth.. so the 12mm thick of stainless will hit alot darn harder with the added mass.


and a video of it running.. alot better balanced now
i have come to the conclusion my kitchen floor is horribly uneven.. at work it translated alot better.. seemed to keep getting stuck in the middle of the lino squares making me think there is a massive dip in each one >_>

Wow it has been a long time since any robot related projects..

I don't know if its just me but reading over stuff you have said from years ago just makes you want to punch yourself in the face >_>

anyway, I have been rather busy with car projects and work but I had this urge to do something RC and destructive so I dragged out the old melty project from under the bed and dusted it off to see what shape it was in.
The frame had a fair beating from Glen but no hits seem to make it more then 1/4 of the way into the soft Ali so I figure why change the material when it worked so well.

I had been stockpiling some scrap bits of Ali so I whipped out a new frame, not very many changes, removed weight from some spots that were overkill thick.. the previous motor mount was only 3mm Ali and it bent somewhat so with the weight changes can use some 3mm steel. also the teeth are about 10mm bigger.

Electronics wise will need a new Lipo. the accelerometer and micro controller seem perfectly fine as they were wrapped heavily in foam.
When the new Lipo turns up will tidy up the wiring and reload the code with some changes that i have been reading up on to help it translate better.

that does look pretty epic

New lipo? But they work better in banana config.

Also - where are you gonna test it ;.;

What would it take to make a Meltybrain translate faster? A featherweight bot with a steel shell would be tough to beat.

I love a robot that basically a big lump of nicely machined metal

haha a feather version costs too much money that I'm not willing to invest and yes without somewhere 100% safe to test no way i would make 13kg of possible uncontrollable steel loose not in an arena
But i can just section of a bit of the workshop floor at work for a tiny beetle

Banana Lipos are the new go to source of batteries

@Nick - i was reading through some posts on their forum and actually had a good read of the code and there are heaps variables in the code that you can change that i never bothered to fiddle with seeing as it worked to some extent.. like you can adjust turn speed, rpm to begin translation, also from what i read the closer to the centre the accelerometer is the faster it can track. not 100% sure on that one but some experimenting will prove that.
Basically just needs fine tuning, got somewhat overwhelmed last time and got it to the point of running then needed to have a break from it.

I really like the low number of moving parts and the huge amount of kinetic energy these bots have; if I didn't already have too many projects going, I would love to build one.

Interesting info about the code and accelerometer, I hope the new build goes well for you.
