I built my humanoid robot using Servo Erector Set brackets. He’s is based on Humanoid Pete robot with double-knees. He has 14 Tower Hobbies TS-70MG servos (similar to Hitec HS-645MG) for legs and 11 Futaba S3003 servos for arms and head. He has SSC-32 board and is waiting for the Lynxmotion Visual Sequencer software. I’m thinking of adding waist rotate but I’m not sure which SES parts to buy for the waist rotate. He already have the Humanoid Biped Torso A chassis. I need a head with a video camera. I didn’t get him to walk yet. Any suggestions? He is actually my third biped robot. The first robot was made from thin wood boards and the second robot was made from thin plastic sheets. The first and second robots used Arduino Uno boards.
Very cool!
Perhaps flip the torso over entirely and use what would be the head rotate servo as a waist rotate?
I notice that there are two servos for the knee - why? Also, you might want to rotate one of the servos at the hip so the robot can rotate the entire leg to more easily change direction. Can the robot support itself? You don’t need a walking algorithm, just send signals to the servos so it stands vertically. The arms look great but might be a bit heavy.
I thought that I need double knees so that the robot can squat. flipping the torso over won’t work because the torso could be supported on one side instead of two sides of the servo. I know that someone used servocity.com/html/standard_ … locks.html will work with SES brackets.
Unfortunately the hole pattern is different - unless you are ready to customize…
I am going to convert my robot to gorilla-walking style. I still can’t get my humanoid robot to walk without falling down.
Some things to consider:
- The arms have a LOT of servos and weigh a lot; the servos in the legs will be under a lot of stress. Most humanoids use 3 servos per arm - you are using 5.
- The added degree of freedom in each leg will not help it walk. Consider something similar to the Kondo (17 DoF vs 23Dof):

I downloaded the manual for the robot in robotshop.com/kondo-khr-2hv- … bot-3.html Is it possible to build my robot that is similar to the kondo-khr-2hv-humanoid-robot?
Yes - and you should have more than enough servos and brackets 
You may need to do a little bit of adapting.
See page 16 for how it should look:

The translation of Japanese to English isn’t good. I think that they used Google Translate or similar website instead of a human translator. Assembling the Kondo robot looks harder than assembling the biped robot using the Servo Erector Set. Why are the Kondo’s legs “L” shaped instead of straight? I found this website davidbuckley.net/DB/Inspire.htm#BigFoot while I’m visiting Arduino’s forum website. Maybe I’ll try making one of the bipeds shown in that website.
No clue.
I think that my robot needs some kind of counter-balances. Would raising the arm on the same side as foot tilt work?
It should. The idea is to center the robot’s weight over the contact area (the foot). You can also use the arms to counter-balance the weight as it moves forward.
