    Update on the legs. They're balancing alright but its still not rigid enough since the servo's can move/slip out of the connectors I printed for them. Normally you put 4 screws through the holes on the servo and mount that to whatever object but i'm currently using pegs that slide in. Works good for fast prototyping but ill have to design something more permanent later.

    Excuse my dirty desk/room lol.

    I put it on hold after I got to the waist. I have to replace all the motors which would be a bit expensive so its on the backburner till I got more money. (Just bought the Vive for $900)

    I'm rebooting this project with a all new redesign of the robot. The torque I needed is to much for almost all servo's except for the really expensive ones so I basically went and added 1 stage gearbox's to all the joints to get that needed torque. Also went from 15kg servo's to 35kg servo's so with the 3-1 gear ratio I should have 105kg per cm of torque or 10.3 N-m in the joints now.

    (The large gear is pretty huge but I was able to squeeze all the space I could out of the legs and get them about the same size as my last design. Still have to figure out what to do for the arms. )

    Also, I haven't quite figured out the hip area yet so that will probably change a bit. The thigh and below is working though.

    I have an update actually on my robot. I have the first rough draft of the hip/legs done and actually built the hip section/left leg with my 3d printer so all that's left is to find any tweaks I can do to make it sturdier/more rigid and then print off the 2nd leg and i'll finally have half my robot done.

    Update on the knee. I have the gears meshing together a lot better now so that the joint turns much smoother. Im redoing all the joints now with the same improvements. Getting a lot closer to finishing this leg so I can build the other and test it walking.

    Latest Update:
    The robot on the left is my version and the one on the right is my reference. You can see the legs are different on mine because as I work my way up from the feet I create new parts to fit all the internal stuff that makes it work. I have most of the hip section fitting inside the hip shell but there's some parts sticking out ill have to work out later.

    Now, if I keep going it should look something similar to the robot on the left with its current size scaling. I realize the hips look a bit to set apart but with the current design I can't get them to much closer without compromising the legs range of motion.

    To conclude, I only have to print and replace the ankle joint today so when that's done the whole lower half of the robot will be done. If everything works out and i'm happy with its performance, i'll order a new set of servo's and print the second leg. That should take around 5-7 days for my printer. Pictures and video's to come sometime in the coming week.

    P.S. I've been working on this for just a bit over a year now :).

    Very neat! From what I see, you have made the robot up to it's hip at this point?

    Yep! I don't have the hip outer shell that will fit over it made yet since I have to redesign it but everything inside of it and below I've already printed and assembled!

    More progress being made. The hip section is going to have a shell put over it to hide most of the ugly frame but ill have to get creative with it and add a stretchable material to allow full range of motion. It's also heavier then I thought it would be for being made of plastic and 50% hollow. Probably don't want it falling over anymore lol.

    Anyways, i'll continue working on it. I got two more servo's to add in the hip area and some other adjustments here and there before I can really start testing it.

    Can she support her upper body?
    Will she walk with the weight of her upper body?
    Are her joints on her knees flexible and sturdy enough?
    Have you thought if her left foot has the same weight/width as her right foot?
    Is it possible for her to sit on a chair?

    Well, I'm just giving my idea. Keep it up.
