Hello everyone!  My name is Jeff and I have been involved in robotics since my first robot combat exhibition at Kansas State University in the fall of 2006.  I also competed at Hord Fall 2007 before taking a break from combat.  I was involved with FIRST robotics as a student and then mentor from 2008-2014.  Lately, I have been getting my fix through Colorado Space grant.  Now I am back into building combat robots and my first competition back will be the Sparkfun AVC. 
I am joined by fellow student and robot builder Isaak.  He is working on a bot for the AVC.  More details on that to come...

Here are my bots:


This is the 5th iteration of an antweight vertical spinner I have made.  It's a wedge with a drum.  Or it might be a drum with a wedge. 


Mostly unchanged from his last fights at Hord Fall 2007.  Dusty uses many old school parts such as banebots drive motors and an Ant 150 ESC.  Winner of Hord Fall 2007 with 5-1 record. 
Here is a quick vid:

Isaak's bot:
Something will go here eventually.

Hello.  This is intended to be a non-biased and actively growing list of all resources available for building 150gram, 1 pound or 3 pound fighting robots.  Please leave feedback on parts or vendors in the comments section! 
If you were looking for information on how to build a fighting robot, consult the learning section or go here

A giant list of links (some are broken) can be found here.

Kits:               Viper kits require very little machining. Servo magazine bot kits are more like instructions and materials                               Competitive ant and beetle kits               Currently one antweight horizontal spinner kit

Learn: The newest getting started guide                                         Intro to fighting robots.  Also a blog about combat robots.                    Very in depth guide to combat robots.  I still haven't finished reading it, but lots of good info inside.                    Lots of different tutorials.  Just keep in mind that some of the component information is outdated now       THE LIST The answer to "What do I need to build a robot?"                           I just stumbled upon this, but it has lots of frequently asked questions about the sport      Information on pneumatic systems                         A few guides and tips here\                     Excellent guide on building a robot with common household tools       Video series on building an antweight

Robot Parts:

Speed Controllers        "vextroller"           Scorpion mini

Motors              similar to B16 with S7 motor shaft

Li-po Batteries      Self-termed "battery Heaven"  Higher quality batteries, but at a price

Wheels and hubs

Building Materials:                              Huge online store for nearly everything mechanical.  My favorite source for Garolite and round belts.                                Similar to mcmaster, but with stores around the Country                          Good source of metals and plastic for building                  Surplus titanium               Titanium, garolite, lexan, bolts and some other useful building parts             Aluminum Extrusions               Mostly "Canada only"           Another online industrial supply

I'm looking to upgrade to a 2.4Ghz system for my insects.  I've seen a lot of options, but I am not sure which one to get.  Can anyone give me some guidance?
