I've read this whole thread, and I really have enjoyed watching the tit-for-tat battles, and the creativeness of each entry! A few posts, though, are obviously not really competitions, and I think there needs to be a few more guidelines to make things less vague and the battles outline more definitive victory conditions.
Anyways, to help with this, I propose the following:
(I've seen several entries where the bots basically pass one another and drop off the opposing edge; not really a victory in my books. Be a real robot and PUSH THE OTHER ROBOT OVER THE EDGE! All other outcomes are failure. So..)1) Victory is only achieved when one robot pushes the opposing robot over the opposing edge of the field.
Basically "Robot Sumo." ;2)
(Some entries have robots on tethers and robots with several "pieces", where victory was bascially won by leaving one of these pieces behind. So...)2) Battlebots should not be made of more than one single "chassis." No Tethers and no separate modules. Boxes, Traps, and Chains are allowed, as long as they are connected to the chassis and they do not drag out more than the length of the chassis (in which case it will be considered a tether or separate module).Note: One way to allow any design would be to add one victory rule addendum to enforce preserving all pieces of a battlebot to stay on the field:
1b) Victory will only be made when all pieces of a battlebot remain as all of the opposing battlebots pieces is/are knocked off the opposing edge.
Also, we could use the goal "balls" as the tag to mark the "main" part of the battlebot. This will require all bot designs to incorporate this goal ball into the design. Thusly:
1c) Victory will be achieved when one battlebot successfully pushes the opposing battlebot's "goal" ball over the opposing edge first.
There may be other victory conditions to be achieved, but for a simple "sumo" competition, these above three conditions should be sufficient.
(There is a limit to the number of pieces that can be placed on the field - this can allow people to make battlebots with a majority of these pieces, leaving the opponent insufficient parts to make a contender. So...)3) Battlebots should be made of no more than 60 pieces, not including the goal ball.NOTE: Of course, these parts limits could create "Weight Classes," where robots of only a certain part count can contend with other bots with similar part counts. Just a thought... :2)
(Some entries violated the "half-way" border....)
Try a level like this
(this is still a prototype level, but at least the door mechanism is a working proof-of-concept)...that uses dynamic objects make it easier to impose borders, and it moves out of the way after a few ticks (unless a bot interferes with the "door" mechanics) allowing the battle to commence.
Anyways, those are my ideas. I think with some more rules we could also set up battlebot contests with multiple rounds/heats and elimination challenges. Hope all this helps!
