It does actually have a slow stable gait, not at all like a standard humanoid robot. A single footstep takes about 2.5 seconds.
That said, the foot itself is actually 4.5" wide in the front, and 8" long, so its larger than it looks in the picture (the legs are fully extended as well). I also have an ADIS 16355 IMU for feedback. Both Jon Hylands and I have had a Bioloid version of this leg design walking, which had an even smaller footprint (to scale). Check the pictures earlier in the thread to see the prototyped Bioloid version.
Better picture of the feet here:
You’d be surprised on the footprint size required when you’re not just ‘blind walking’ without an IMU. The Farrell’s have a bot bigger than this, with an even smaller footprint…
wowy7- The AX-12s are what come with the Bioloid kit, these run on 21v or so and are significantly more powerful.
Yup. Standard voltage is 18v. They’re intended to work with 5S batteries, which peak around 21.5v. I’ve spoken with Robotis at great lengths about these, well within their spec.
I’m looking at 2x 18.5v 2200mAh 30C 5S LiPo batteries.
This is truly amazingly cool Tyberius. I bet this have been a fun weekend putting this ultimate monster mech together 8) I know if had something like that with so many expensive parts I would pretty nervous and strict when doing the mounting. And having in mind the incredible torque of RX-64 you don’t have to be afraid of pinching your fingers… they would probably cut them off instead
Every aspect of your work is very inspiring Tyberius! Keep it up!
Your massive mech is awesome! Beautiful craftsmanship!! It already scares the hell of me and it even doesn’t have guns at the time. The thing is HUGE!
I bet it’s got enough power to load it with a tons of fire power.
I would imagine it wouldn’t be too difficult, however I’m using a Bluetooth PS3 controller due to it being easily paired with the bluetooth on my Gumstix.
Here’s an update, guns still need painting and mounting finished, still needs armor as well.
just curious but do you actually have that walking yet? there are a couple things that seem like they would present a serious challenge to this being an effective combat design. in particular your CG is way way way up in the air, it has a fairly wide stance, and really small foot profile. it you got it working then great of course, but just looking at it from 100 feet out the design approach seems counter intuitive and more aimed at asthetics than functional operation.
Its built around Jon Hylands’ Microraptor, both he and I have built AX-12 based smaller versions of this same leg design and it works rather well. We’ve both had it walking and walking well.
It does not use a standard humanoid walking gait, hence the difference in COG placement and wider stance. Feet are actually 5" wide and 7" long, they just appear small due to the perspective. Proportionally they are just about the same size as the bioloid feet. Also, the way its standing in the pictures isn’t a proper stance, the legs are much more upright while walking.
This type of setup would not work well in say, RoboOne style competitions however. Its not intended to take physical hits and relies on a higher COG to walk well.
Just for show you may want to get a laser pointer for each airsoft so it can be energized prior to shooting to point the intended target. One can get the small laser pointers at Walmart for $2.49 each.
