Bipedal Humanoid Project (in progress)

Introduction

This is an ongoing project that I'm currently engaged in and work on my spare time. I'm building a budget humanoid robot based on a myRIO embedded device as the main intelligence. The idea is to build a walking and interactive humanoid with the help of LabVIEW Robotics and several other toolkits.

Why?

As far as I can recall myself getting involved in projects (specially robotics-related ones) I always saw building a bipedal humanoid as the "grand-challenge" I want to take up. Little did I know at that time that I'll be building robots for years ahead and one day actually decide to do it. Recently I had an amazing opportunity to evaluate and use the myRIO embedded device from NI. By using it and also exploiting the knowledge I have gained over the months working at National Instruments I now believe I can accomplish this. So several months back I have finally decided to pursue this life-long dream of mine to build something that people first think of when you say the word "robot".

Mechanical Build

I will try to be upading this post with lots of detailed information on every update so this paragraph is mainly just to introduce the reader to what parts I will be using and why.

Parts I have used:

• General usb Logitech QuickCam Communicate STX webcam I have found on eBay which to my mind looked like a real "cyber" humanoid head. Even though it's only capable of delivering 1.3MP, 640x480 video, for the myRIO image processing this will be just about right (as this is quite performance-demanding job).

• Inexpensive Tower Pro mg966r high-torque servos I have had from the hexapod project.

• The most basic and cheap servo brackets I could find (available at any robotics-shop) were used for the frame.

• A PCB breakout board for getting DIO lines out of the myRIO and having connections for the servo motors, voltage meter, power-switch and batteries.

• Two LifePO4 2000mAh batteries that I have sandwiched in between foot brackets for each leg to get the center of gravity lower (quite important for an application like this). LifePO4 was chosen due to it's voltage levels which fit myRIO and servo motors perfectly without any need of conversion.

• Tons of other miscelanious parts such as nuts, bolts, cable ties, mech wire guards and etc.
