- "Because of the weight limit, we're allowed 200 kilos, so obviously it's a big advantage … it means we can have bigger weapons."

RT81, alternatively RT 81, was a walkerbot which fought in the New Blood Championship, broadcast as part of the second series of Robot Wars Extreme. In its only appearance, it lost in the first round to Chip and Edge Hog.
- "190 kilos, the centre stand turns 360 degrees, the separate top turret also turns. It has an electric hammer, is protected by a lorry rear tyre for protection, but slow."
- — Jonathan Pearce describes RT81
RT81 was a circular shaped walkerbot, with a chassis made out of a lorry road tyre and armed with a large electric-driven hammer mounted on a 360-degree turret. The robot also featured side skirts around the base of the tyre, but was extremely sluggish with a top speed of only 2mph. RT81 was painted yellow and black in its New Blood appearance.
The name derives from its owner, Andrew Lovelace's involvement with the Round Table, hence RT81. The robot's statistics table specifically styled the name as RT 81. The robot was originally known as RT80 when it attempted to enter Series 6.
RT81 originally attempted to qualify for Series 6 using a white colour-scheme, at the time known as RT80. However, it did not win its qualifier battle, and instead earned a place in the New Blood Championship through direct application.
- "RT81 can only get up to 2mph, so don't expect Grand Prix speeds."
