We've noted development of drum-spinner bots designed specifically to defeat our very successful D2 beetleweight combat robot kit. In response, and continuing the combat robot "arms race" :) , we are developing a weapon module that would replace the wedge for fights against these types of robots.
We will test this new weapon at the "Great Seattle Bot Brawl" at Robothon on October 1. Assuming this new weapon proves to be as successful as we expect, we will make this available as an add-on accessory for our D2 combat robot kits.
