This is Bob-2858, a robot designed solely to burn his way through thick doors. He is accompanied by Sergeant Jerry, who you can't see because he's not in the picture frame. He's trying to blow through the door by himself to get to the aliens. Idiot.
About this creation
Sergeant Jerry is trying in vain to blast through the door with his laser.
Bob glides along to melt straight through the door with his plasma torch (Jerry is killing aliens coming to attack Bob).
ZAPP! Jerry takes out the aliens behind the door (laser set to stun, of course, so he can interrogate the aliens). If Bob had proper Human emotions (or a mouth), he would be laughing his head off.
