Zenta Strike Again! Archer the Biped!

Wednesday, July 28th, 2010

If you’ve read this blog at all over the past few years, you’ll know we’re big fans of Kåre Halvorsen’s (aka Zenta) work. Father of the very popular Phoenix Hexapod Kit, A-Pod the ant bot, and more recently the T-Hex Hexapod (available soon in kit form), it’s very obvious that our Norwegian friend has an incredible grasp of Kinematics. Some might even call him a Kinematics Kung Fu Master. It’s only natural that he would blow us away with his insane math-kinematics skills when he decided to take a shot at a biped walker. Well folks, he did not fail to impress. Utilizing the new Arc-32 board from Basic Micro, armed with only standard hobby servos and an inhumanly good grasp of math, Zenta has created a new biped named Archer.

Okay, so bipeds have been done before, what makes this special? Not only does it have some of the most impressive Inverse Kinematics I’ve seen on a non-professional level, it utilizes a pretty innovative COG-Shifter mechanism that can slide the battery and onboard controller from side to side to assist in walking. Want to see it in action? Look no further!

Also, if you can’t get enough of Kåre and his awesome Norwegian accent, check out this ‘behind the scenes’ video where you’ll be treated to his very impressive workshop and a demo of how he controls his various robots:

Boston Dynamics does it again

Whoa. Just Whoa.

I won’t even pretend that I understand all that is going on in the walking gait here, but this is darn near human-like in every aspect. And being able to walk like that is one thing, being able to recover from a sideways push is an entirely different accomplishment all together. Absolutely brilliant.

Hagetaka: A Bipedal Combat Robot

Thursday, April 16th, 2009

Remember when we teased you with a stack of RX-64 servos? Well its time to unveil a bit more of what we’re working on for the upcoming Mech Warfare competition at Robogames 2009. Meet Hagetaka; a 7DOF per leg biped built around the powerful RX-64 servo from Robotis. This robot boasts 14 RX-64s, 2 RX-28s, a custom aluminum chassis machined by sponsor Big Blue Saw, an onboard linux based Gumstix computer with a PS3 Sixaxis controller , a WiFi video server using a Headplay Personal Cinema System for remote piloting, and of course dual automatic airsoft guns. Video and more info will be available in the near future, and be sure to check out the June issue of SERVO magazine for the first in a series of articles detailing the build process of this Mech.
