AX-12 & AX-18F Dynamixel based Interbotix Hexapods

What you see here is a prototype but you're for the most part correct. I ended up adding front/back plates with a bioloid bracket hole pattern on the body so that users can mount grippers, tails, etc. The feet have rubber pads on the bottom that are replaceable and help absorb some of the shock, but the inherent gear backslash helps as well. Also have a foot pressure add-on kit in the works that utilizes FSR sensors.

AX-12 & AX-18F Dynamixel based Interbotix Hexapods

Looks fantastic! and definitely one of the fastest out there (faster than those new Japanese competition quad-pod monstrosities).

Correct me if i'm wrong but seems like this ingenious structure was put together with standard Bioloid components + 3 custom designed flat (CNC'd) parts as in the picture below:
1) leg
3) foot
4) body back / belly

2) metal struts / pillars to support the leg and body dual-sides.

?

The impact on the foot may be quite high and have all kinds of side effects. Why not make the foot of a soft rubber material?
Maybe find a way to put a spring and potentiometer in the foot that will tell the CPU how much force is being applied to the foot.

Hey guys,

Wanted to share some of the prototype work I've been doing for a new product that is upcoming. These are AX-12+ and AX-18F based hexapod kits powered by the ArbotiX Robotcontrollers & NUKE Inverse Kinematics Engine from our partners at Vanadium Labs. All the software is open source on these as well.
