There is something wrong. Is it me or is it the BOE-Dog?

I turned my BOE-BOT into a makeshift walkable dog.
Then After testing it, I unplugged it from the computer.
And when I turned it On again.
The voltage regulator heated up!
WTH happened?

    Who knows?

    There's no particular reason why this should happen. There's no change that would account for a higher current drain when a BoeBot is unplugged from a computer. There's no change to the program stored in the BoeBot and there should be no change in behavior of the BoeBot. Something else must have happened and you're not explaining enough about what you have for hardware or software to puzzle it out. If you want specific explanations or discussion, you really have to give more information.

    Maybe the bottom of the board is touching something, so it has a short circuit.

    I just found out that if I plug anything into Vin and Vdd Ports. It short circuits.

    You have some kind of short circuit between Vdd and ground (Vss). You're going to have to find it somehow. The most straightforward way is to disconnect things, one at a time from Vdd and Vss, probably on the breadboard area and the servo connectors until the short circuit goes away. If that doesn't do it, disconnect from the Stamp I/O pins one at a time as well. With the BoeBot, there's usually only insulated wiring underneath the board, so that's not typically a problem unless it rubs on the bottom of the board with movement.

    Watch out for component leads (like resistors) brushing up against eachother on the breadboard. This can be a major problem and cause very unexpected results.
