Issy
@ June 7, 2009
Thought I would post about my latest robot: Issy (short for IssyDunnYet). I started actually making this robot run around about 3 weeks ago, and amazingly, it's ready to go in time for MechWars next weekend at Robogames in San Fransisco.
Issy is built out of 13 AX-12 servos using the bioloid frame kit, lynxmotion SES brackets for legs, and a custom AVR-based controller with an XBEE wireless link back to my PC. For competing in MechWars he is carrying a Wifi camera (through which I watch and drive), and an airsoft gun, as well as the required scoring system.

Whoops, forgot to update stuff here after robogames. After quite a bit of work onsite, Issy won the Gold medal. Since I wasn't entirely familiar with the Bioloid servos at the time, I made a number of mistakes in how I was using them (and so they were severely underpowered). I ended up removing Issy's 3rd DOF in each leg to lighten him up and reduce the load on his leg servos. I also had to slow him down to avoid the scoring system detecting his rough walk as a hit. He's since been rebuilt as a slightly smaller fire fighting robot. A video summarizing Mech Warfare year 1, and showing lots of Issy, can be found here: http://www.youtube.com/watch?v=rQ_bAsbZLt4
For anyone wanting more technical details, I've posted a tutorial on building Issy. His source code has also been open sourced and is included as an example in the ArbotiX release.

are those brakets custom or are they from a store

The brackets are mostly the
The brackets are mostly the standard Bioloid brackets for the AX-12. The upright portion of the legs are Lynxmotion SES parts.

Way Cool
This bot is super creative but I'm wondering how you get the airsoft guns to fire?

The ArbotiX robocontroller
The ArbotiX robocontroller used (available at Trossen Robotics) has motor drivers onboard which can handle the smaller tank guns. For larger guns, a larger transistor will work.

I've updated the pictures a bit, the old pics were before I had all the sheathing on.
