CONFIRMED ANSWER: POSSIBLE from killing the robots in Dr. Volt's quest.
Ok, Recently, I have received a battle core from..
(1) clicking on the button that it tells you not to push
(2) beating the mega driller/ coke dude over numerous times.
It was said to have a drop rate of about 5 out of 100 (5%).
Surprisingly, I gained a battle core on my non-stop 13th kill and then I got ANOTHER on my 26th, which means that out of my trials, I have scored a drop rate of 1 out of 13 (7.96%) chance of scoring a battle core by clicking on the "DO NOT PUSH" button.
Then again, I wouldn't be surprised even if you have done this 50+ times because it is extremely rare for this drop (and I know that many people have said it is impossible to receive such drops like this), but I bet you that all those people who said it was impossible either didn't try hard enough, or didn't push the "DO NOT PUSH" button.
I've gotten onto DragonFable to test whether or not you can score a battle core from beating the robots WITHOUT pushing the "DO NOT PUSH" button. My trials came positive and I received a core on my 46th time. Unfortunately, I only had enough time to do one trial, so my result may be inaccurate, but through my trial and error, there is 1 out of 46 (2.17%) chance of dropping a battlecore WITHOUT pushing the button. (2.17% is much less than the previously thought 5% chance).
I am sure that the 'DO NOT PUSH' button will increase the chances of getting a B.C. (Oh and also, I received a filament too if you want to make a 20 watt tog which you need a DA to equip using the steps as I mentioned above).
SUMMARY:
(1) it is POSSIBLE to get the B.C slaying robots
(2) Pressing the "DO NOT PUSH" button beforehand will increase your chances of a B.C drop significantly (8% drop rate).
(3) It is possible to receive a B.C WITHOUT pressing the "DO NOT PUSH" button but with a significantly lowered drop rate of 2%.
(3) By pushing the button, it is also possible to receive a 'filament' which is required to make the better version of the standard robo-tog pet, the 20Watt Tog (which requires a DA I believe).
its really rare
None you get a battle core at crsoc
