Even I didn't know microwaves have USB ports.
And yeah, the teleportation, the robot SOMEHOW moving without actual motor/servo parts, also nowhere being a battery nor cables for it.
The thing here is, it's the 'goofy' genre of the game. Most of the times you have to interpret it as "imagine you just figured it out and it worked". And for the teleportation, it's an exaggeration of how sneaky the robot is, that it looked like it teleported (while it actually teleports behind the scenes).
