Thats awsome! Mess of wires though…
nice!!! OMG cant wit to see a vid
SICK!!! lol, the elctronics look so small, maybe u should make a GIANT ABB to make it look more to scale
I bet he has a bunch of tie wraps to take care of that when he has the wiring routed the way he wants it.

You bet, bags of wraps, sleeving, clips and brackets. Just haven’t got that far yet.
Well the wiring is good enough for now. I started out making custom servo leads cut tot he exact length but honestly, I just lost patience and used a bunch of extensions instead. I want to do some testing before I put too much looks into it.
The 18 servo power leads connect to 8 power panel leads and plug into the power distribution panel which runs to the Watts-Up Power Monitor and data recorder, then plug into the Y-harness on the packs.
I’m running 28 cells (2X14 cell 8000mAh packs) for 8.4V at 16,000mAh. Which may be overkill. Once I can do some time tests of walking, I can record the power consumption at certain points in the gait and calculate my total run time on a given mAh pack. Then use the pack that gives me the run time I want. No point having an 8 hour battery if the servos get hot after 10 minutes. The packs are still wired as 14 cell in series so the power meter reads 17 Volts but I’ll be rebuilding the packs. I made them originally for a Giant Scale 3D plane.
Here are some pics so far:

And since the 209 Scout has become the official model of the Giant Hexapod, here are a couple of the scout under the Hex.

It is looking great!!!
what’s it weigh?
Looks fantastic, Evolution!
…but d’yathink that maybe you could make it…ah…y’know…kinda…a little bit…umm…BIGGER?

WOW! This is looking awesome! I hope I can do as good with Walk 'N Roll when I get to building it. I’ve good good ideas about how to do the wiring now.

jumps on hex WEEEEE HORSIE!!!
thing looks great, should bring it to parties and let ppl get rides from it
Pretty cool.
I think if I built something that large though my wife would start to seriously question my robotics hobby. The irony is I have several r/c planes that are larger and she has never questioned that. I can’t imagine why the discrimination is there.
Looks awesome!!
Need to see a video with 209 Scout wearing a cowboy hat and ridin’ that monster. lol

It’s probably because the planes require you to be present and control them. Robots can run around on their own.

Thanks guys. I’m just finishing up some last mintune things on it and waiting for linuxguy to start on converting the tutorial program to run on my Atom Pro 28. I picked up some little boots for it today as well. I couldn’t think of what to cover the sharp ends on the tubes with and then I found these little rubber covers for the bottom of chair legs. They fit like they were made for it.
I’ll post some pics tonight.
what’s it weigh?
So far the total weight is 15.5 pounds with the 28 cell pack. My leg testing gave me 6.4 pounds of reliable lifting power. Stalls around 8 pounds. So I can lift 19.2 pounds with 3 legs and 38.4 pounds with all 6 legs. So ina tripod gait the 3 down legs are only holding 15.5 pounds right now.
If I use a 14,000 mAh 7.2V lipo pack I have, the total weight is 12.1 pounds. Plus I can lighten the chassis and brackets alot by drilling 3/4" lightening holes in them. But it’s alot of work if I don’t need to so I held off on it.
So far it looks like it should be able to lift itself plus a 7 pound payload with the lipos on. And that is not at stall and lifting with only 3 legs. I tried base my weight and torque numbers off 3 legs alone since most of the time in a tripod gait, 3 legs are doing all the walkin’.
I can’t wait to try it. linuxguy, thanks alot for helping me with converting the program to Atom Pro. Your servos are packed and ready to go.
Have you conneced the ssc32 directly to a computer and run some routines to see how well it supports itself?
No, not yet. I’m actually doing that right now.

Hold that package.
I will do what I can when I can, but I have hit a snag in getting my main PC working again. It seems this time it took out the motherboard and CPU. I have another CPU here I will try, but it is only an Athlon XP 2100+. The apparent dead one was an XP 2800+.
I got the new motherboard and installed it, so I just have to take everything apart again and swap the CPUs. I can’t do hardly anything with robotics until I get this PC working again.
