This a robot I'm working on.  I wanted to get a few vehicles under my belt, and I thought this may be a stretch but probably qualifies.  It's supposed to be a obstacle of sorts that people trapped in a Colosseum would have to attack/ evade in order to free themselves.  I'm picturing it sitting in the middle of an arena motionless and the player has to go and pull the handle to trigger the slot machine and defeat it to open the door.  Depending on the results of the reels the bot's arms would change and would be more/less difficult.  I'm thinking about calling it SlotBot.  Clever right?
