I get an error regarding engine tasks upon trying to use this bot. What went wrong?

NOTE: Sorry for forgetting an end in the code, I quickly put it together due to how impatient I am right now >_<, but in the actual code there's the necessary end. I can't edit it due to the text not showing up in the edit mode, too. Sucks.

[editline]22nd July 2015[/editline]

EXTRA NOTE: For some reason the | operator doesn't work in the CapabilitiesAdd func, after I replaced them with "or" they worked fine, but I still get the error revolving around engine tasks on the bot being spawned.

Oh god... There is just so many things wrong. For a start, you need to recreate the animation system which is ran from the task.

[ARitz Cracker]

You shouldn't have replaced | with "or". That was a binary operator. Use bit.bor(arg1,arg2) instead.
As for your other issues.... Good luck, man.
