dead robot strategies are good, ad they provide a good insurance also. god forbid, your robot has a major malfuction, and it can't move, or move much, and you've already done the play dead strategy, you can pretend to play dead. then, the other team will be very wary of you, and it may distract them, so your partner can go and do things. it would be interesting to see how long the other team believes you're just playing dead, and not really dead.
