Cool...Seams very Hegataka esq. I hope you don't run into similar problems...

I can't wait to see this thing walking around. Why couldn't you just use the bioloid controller by the way.

In anycase...cool.

that's what i'm planning to do but I still need a control board to operate because my origninal board is broken

As long as you keep the payload down, you're ok. Microraptor, and the original Hags all walk.. they just don't have a huge payload.

that shouldn't be a problem really. A camera, controller, and guns that's all i'll need

Also make sure you have your legs aligned correctly to best distribute your weight. The posture you have in those pictures may look cool, but its unnecessarily stressing your motors. Ideally you want to maintain something similar to this:

Um, you'd be surprised. The bioloid humanoid has been shown to have about a 500g payload - and I'm not even sure how long it ran with that. Each (tank) gun is about 100g, a camera is about 90g and then you have to upgrade the batteries to handle the extra payload and power the camera.

Personally, I'm finding that Issy is overheating servos after about 12-15 minutes -- and he's a quad. The shutoff temp might be a little low, but I really hate to raise it all, i really don't want to burn up $40 servos....

I never thought I could over weight bioloid servo's THAT easy Fregs what camera did you use and how much did it weigh? Can you also tell me what type batteries you're using I still think I can pull off the weight limit but i'll need expert help.

OK. my initial numbers were off I admit... here are ACTUAL measured values, that I posted in another thread:

Trendnet IP Cam = ~90g
Tank Gun = ~100g
100bbs = 12g
Hopper = probably 5-15g
AVRRA Scoring Board = 30g
Lexan 3x3" plate + sensor = 20g
pan and tilt servo (just about everyone wants them) = 60-100g
Armor, velcro, other incidentals all add up to more weight

So, estimated biped payload (from what we've seen, 2 tank guns, ~300 rounds, 2 scoring plates) = 416g. Add pan and tilt you are well over 500g. Add weight for heavier batteries. You also gain some weight back from removing the upper torso..

Sigma, if you wouldn't mind, would you cut my bad numbers out of your post, just so we don't have bad data floating around as new builders read up...

alright but i'm using one gun i'll need the pan and tilt unless I should try a new configuration

I think the lower legs of a standard bioloid humanoid could carry the weight.... IF you literally just had a turret on top of the legs with your camera/gun/electronics. Problems that would rise with this configuration: Unable to get back up on your own, and would have to do some pretty tricky work to get an upper torso/turret frame lightweight and compact enough while still housing everything.

yeah I thought as much so I suppose a new
config is in order but i'll have to figure a way to upright
also and that may be tough cookie in itself.

UPDATE: I rebuilt the leggs and reduced the main turret down however I still have to design a self upright system pics soon

I havn't posted quite as much as I want but it seems Tyb
was right. I ran in to so many problems tring to mount the necessary componets
just to realize, I still havn't mounted the self right servos nor the control board
in short I failed. Guess I gotta do a quad design

Hey Sigma X,

You don't fail, you learned. Sometimes the best lessons are learned first hand.

Thanks it's what I needed to hear I'll give up on the biped design
maybe i'll try an Issy design with a few changes or cource
