It's about 26.5" tall.

Are you one half of Farrell robotics? I forget their usernames on here...

I am not, the Farrells (Father/Son team btw) are just friends and were kind enough to allow me to use their gumstix controller and software. Their bots are indeed impressive, just wait until you see what they have up their sleeve currently =) VERY exciting and some amazingly engineered bots, they're one of the sole reasons I got into bipeds.

Good news here, power draw was minimal, I had it standing and powering all onboard electronics for over 90 minutes and it barely touched the capacity of the 5S 4000mAh Lipo.

That's pretty damn cool for something so big, and undoubtedly heavy!

Stuart- what robot did you see walking? I'm using the same type of walking gait that Jon Hylands' MicroRaptor uses.

What sensors have you mounted.

Fantastic, Tyberius. Is this going to use a movement system similar to the one I saw a few years ago at RoboGames? That was exceedingly successful

Not in a proper standing position, but gives you an idea of the back side.

Electronics, battery, and weapons mounted. Still need to finish up software and paint the guns black.

Thanks! Plenty of video will come once I get it in walking condition, still in the process of mounting electronics, batteries, etc.

BTW: All the bracket CAD files that I designed for this are available for download, posted in this thread: http://robosavvy.com/forum/viewtopic.php?t=3322

Hi guys,

I guess this would go in the Home Built section, but I like this forum better

This is my Mech, Hagetaka.

This project is still very much so a work in progress, but I figured I would share my work thus far. This is a 7 dof per leg biped based off of Jon Hylands Bioloid MicroRaptor. The upper torso is based off of a Vulture MK2 from the Mechwarrior/Battletech series. I designed all of the metal components in Autodesk Inventor, and had them machined from 5052 aluminum by Big Blue Saw (www.bigbluesaw.com). Total of 14 RX-64s and 2 RX-28s for pan/tilt on the torso. Currently just the frame, servos, and battery weigh about 4 kg, and it stands about 66cm tall.

Airsoft weapons/arms are yet to have been added, and I'm just now finishing work on the electronics mount internally. Should be able to start work on the walking gait next weekend, though I've already prototyped this design with my Bioloid set and had it walking.

Its using a custom Gumstix controller designed by Farrell Robotics...

Anyway, here are a few pictures, click the links below for high res.
