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

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 RT 81
RT 81 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. RT 81 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 RT 81. The robot's statistics table specifically styled the name as RT 81. The robot was originally known as RT 80 when it attempted to enter Series 6.
RT 81 originally attempted to qualify for Series 6 using a white colour-scheme, at the time known as RT 80. However, it did not win its qualifier battle, and instead earned a place in the New Blood Championship through direct application.
- "RT 81 can only get up to 2mph, so don't expect Grand Prix speeds."
- — Jonathan Pearce
In the battle however, RT 81 moved so slowly that Mr. Psycho had to push it out into the middle of the arena, roughly where Edge Hog and Chip were currently fighting. After that, RT 81 suffered numerous axe blows from Edge Hog, and soon began smoking. Edge Hog punctured the rubber armour of RT 81 and got its axe stuck. Chip slammed RT 81 multiple times, but did not cause any visible damage. After Edge Hog eventually got loose, RT 81 was pushed against the arena side wall by Mr. Psycho. RT 81 was clearly immobilised by now, so despite Edge Hog having also lost mobility on one side, it was attacked by the claw weapons of Mr. Psycho and Sir Killalot, before being put under the Drop Zone, where a cooker landed on it. 'Cease' was eventually called, and RT 81 was eliminated from the New Blood Championship.
