Srimech
A srimech -short for "self-righting mechanism"- is a device on a bot that is designed to flip the bot back upright if it falls on its back or sides.
A Srimech is like a hammer weapon, but with no weapons. Is basically an extender on a burst motor. You fire the burst motor when you are on your back.
Some Hammers, most of the Popups and Flippers can self-right.
Not to be confused with being Invertable.
