Looks good but rotating weapons could cut the wire? Definitely a new idea.
I have wondered what the rules say. Can you have a "lightning" bot that EMPs the other bot? Probably not. An acid bot? Again, probably not. A spraying water bot? Probably all against the rules.
Flippers are still dangerous bots. Vertical spinners still work. Horizontal spinners are having problems lately. Wedges are a good idea but boring. Walkers are stupid. The giant bots are just gimmicks.
How about a bot that launches itself a foot in the air, lands on top of the other bot, clamps on and has a high powered drill that drills down into the bot innards? Have the drill be maneuverable so it can drill horizontally into bots that have arms or protection on top.
How about a tangle bot that has a metal net to catch and tangle opponents spinning weapons? After the bot weapon is tangled up, Release the net and turn into a wedge or hammer bot.
