Self-righting mechanism

The Self-Righting Mechanism (or Srimech, derised from the words Self-Righting 'Mechanism) is something of an essential in Robot Wars. It was first used in the Cassius' Pinball run in Series 2, where Sir Killalot flipped Cassius with his lance, and Cassius flipped itself back onto its wheels using its flipping arm.

Shortly after this, robots with flippers began to use them to get themselves out of situations that would previously spell doom for them.

Beginning in Series 4, robots began to include devices that allowed them to self-right. One of these examples was Hypno-Disc, who added a srimech after being flipped by Chaos 2. Other examples of self-righting mechanisms include Razer's "wings" which extend from its sides, Panic Attack's thick bar, which hoists it onto its wheels.

However, on some occasions, most famously Razer versus Aggrobot, self-righting mechanisms can fail. Razer's wings opened too wide, and the tip of it raised Razer off the floor and leaving it unable to touch the floor with its wheels.

On many occasions, Srmiechs require large amounts of gas to gather enough force to lift a robot back onto its wheels. One failed example was the famous loss of Chaos 2 to Bigger Brother, with Chaos 2's flipper having run low on gas and not being able to self-right.
