Hexapods are getting cool (and a little scary)

Not much to do with drones, but for those broadly interested in robotics, this is very impressive. As Kottke says, it "goes from sexy robot to terrifyingly fast insect death machine in about 45 seconds."

That PhantomX Hexapod uses 18 AX series DYNAMIXEL robot servos via TTL not standard hobby servos via PWM...
"On the robotics side of things, many of you have likely heard of the AX-12A DYNAMIXEL servos and Bioloid system from ROBOTIS. These are revolutionary robot servos that have a feature list a mile long and performance that has set a new bar for what to expect from a servo. But to many, the TTL serial interface proves to be a bit daunting, and may put some off from taking advantage of this new and exciting technology."

Aside from the two-way interface with position feedback, the torque and speed of the AX servos leave much to be desired compared to the latest generation HV servos.

John, yes, I have one of these servos, and it is INSANELY fast, smooth and accurate.

But I don't know if it has much power?

It would of course be amazing to build a Hexapod with a quad on it's back...  It's just the weight penalty for carrying around the hexa portion would really reduce the flight time.  Still, this would be really really fun to build.

I think it might work out better if you did something like make a bi-copter using two 450 Helicopter rotors.  Much more efficient lifting, so it could probably fly much longer than you'd ever get with a quad.

These will be the ultimate low impact off road travel machines of the future, should be real exciting to see them progress in size!

Here is a prototype that was running a few years ago built by John Deer I think

Does anybody recognize the transmitter in the video?

@Mark: no idea. looks custom / badass. I think that's an Xbee module on the front.
