Let's Make Robots!

Issy

 
Walks around, wirelessly controlled, and shoots at things. Won Mechwars 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. 

UPDATE 11-25-09

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.

That's something to aspire to! let us know how it goes in the games.
Still amazed when seeing that "skitter" move Mike, cool to see. Have you doine any test combat yet, target practice?

I ran it around for a little while in the office, the guns occasionally jam, but if I keep moving it shakes it loose again. It's definately quite maneuverable though.
