Attrition is my first 12 pound combat robot and has come a long way since its conception in 2008. Version 1 had a shoddy drive and weak frame left it defensive for many of its matches. Now in 2013, Attrition version 2 is the aggressor; its thick S7 armor can defend against any opponent in its weight class but its high-KE brushless drum can toss competitors up to 8 ft in the air! The remaining weight is reserved for a number of attachments which can be employed against specific types of opponents. With these improvements in design, Attrition is currently the #1 ranked Hobbyweight in the nation. Time will tell if Attrition can hold its spot at the top!

Did you machine those timing pulleys yourself? If not, where did you get them?
ReplyDeleteThat drum spinner looks absolutely massive! It's impressive how you got everything under the weight limit. A 2024 revision of Attrition would be interesting!
