Titanic was my eldest daughter’s (then 11) first attempt at building a robot. To keep it simple, it used disguarded parts from the original version of Cannon Fodder and Pants. It was extremely slow, but very easy to drive, with no active weapons.
Ironically, when entered into the Antweight World Series events, everyone expected it to get smashed to pieces, but it went head to head with spinners and came out on top through having a very flexible body.
