Background Information

How does it move?: Ramming, it tries to intercept the opponent by following its own bullets. It reverses direction if it is more beneficial. A small 'wobble' has been introduced inspired by the movement of MaxRisk.

How does it fire?: Iterative circular gun with some protection to avoid shooting straight into the wall. The iteration stops at the outer hull of the opponent. Next to the normal attributes as speed and headingchange, it also takes into account speedchange.

What's next for your robot?: Nothing anymore, as finally it is the highest ranked rambot. This old bot sharpened its teeth.

How competitive is it?: It outranked the best rambot at that time, NanoDeath, in march 2005. In feb 2006, Kev's MaxRisk came along and became the best rambot by a large margin. After more than 10 years a design-flaw was fixed, a clever idea implemented in the gun, and some rather rough movement tweak introduced. Now it is finally the best rambot again.

This tank is completely based on free information available on this wiki.

- RoboRumble ‒ APS: 57.19% (440th), PL: 716-443 (402nd), Survival: 54.73%
- combination of best versions of 0.9j, 0.9g and 0.9k, maybe good enough to become the best rammer
- And it is . . .!
0.9a-l 2017-09-xx Various tryout versions, some succefull, some not so.
0.9a NOT Smart radarturn at beginning of each round
0.9b NOT Brake when sharp turn needed
0.9c NOT Stop iteration just outside hull
0.9d YES Introduce 'wobble' in movement
0.9e NOT Make wobble small and fast
0.9f NOT Fix small fast wobble
0.9g YES Also keep track of speedchange in CT gun (and therefor movement)
0.9h NOT Wobble with extra wallhit prevention
0.9i NOT Again wobble with extra wallhit prevention
0.9j YES Design-flaw: Now shoot full power when close to enemy and wall
0.9k YES Wobble more often (not faster)
0.9l NOT Iterate till hit, even outside battlefield, then warp into field. No bulletpower adaption
