Build a humanoid robot is something difficult. There are many calculations of mechanical, electronic and software / program used to make the robot can move very well as expected.

The following documents contain teory to build a humanoid robot. This document is an old document, but you can use as reference for making humanoid robots, especially in the mechanical section.

These course notes contain a lot of information that should be valuable in your robot building endeavor. Here’s a brief synopsis of the organization of these course notes:

• Chapter 1 is the assembly manual for nearly all of the components used to construct a 6.270 robot|including the printed circuit boards, electronic sensors, motors, and battery packs.
• Chapter 2 introduces robot motor technology.
• Chapter 3 discusses battery technology and battery charger operation.
• Chapter 4 discusses secret construction methods using the LEGO Technics (R) building materials.
• Chapter 5 delves into robotic sensors, explaining the principles of operation and applications of various sensors in the 6.270 kit.
• Chapter 6 investigates how to program a mobile robot to face up to the uncertainties and challenges of practical operation.
• Chapter 7 is a reference manual for the C language software that has been developed for the 6.270 contest.

Four appendix sections provide additional material:

• Appendix A is the student’s introduction to the 1992 class, covering administrative information, the month’s schedule, and the contest rules.
• Appendix B explains the workings of the 6.270 hardware, including the microprocessor board, the expansion board, and the infrared circuitry. This section is written with the assumption of some prior background in electronics.
• Appendix C provides reproductions of the printed circuit board layouts, handy for reference when debugging.
• Appendix D contains an introduction to ordering electronic parts from both the retail and surplus markets, and a listing of more than twenty top suppliers.

ROS is a robot operating system originally developed (2007) in the Stanford Artificial Intelligence Laboratory in support of the Stanford AI Robot (STAIR) project but now (as of 2008) developed primarily by Willow Garage, a robotics research institute/incubator. It is free for commercial and research use under a BSD license. The library runs primarily on Linux but is intended to be cross-platform for Mac OS X and Windows. ROS provides standard operating system services such as hardware abstraction, low-level device control, implementation of commonly-used functionality, message-passing between processes, and package management. It is a graph based architecture where processing takes place in nodes that may receive, post and multiplex sensor, control, state, planning, actuator and other messages.

ROS has two basic “sides”: The operating system side ros as described above and ros-pkg, a whole series of user contributed nodes that implement functionality such as Simultaneous localization and mapping, planning, perception, simulation etc.

ROS is released under the terms of the BSD license, and is open source software.

Applications

• ROS areas include
• A master coordination node
• Publishing or Subscribing to data streams (images, stereo, laser, control, actuator, contact …)
• Multiplexing information
• Node creation and destruction
• Nodes are seamlessly distributed, allowing distributed operation over multi-core, multi-processor, GPU and clusters.
• Logging
• Parameter server
• Test systems

ROS Package application areas will include

• Perception
• Object Identification
• Segmentation and Recognition
• Face Recognition
• Gesture Recognition
• Motion Tracking
• Ego-motion
• Motion Understanding
• Structure from motion (SFM)
• Stereopsis Stereo vision: depth perception from 2 cameras

This a simple robot built based on PIC microcontroller, this single robot has multi functions to do some works.

The robot has the following objectives :

1. Follow a black line track with sharp turns
2. Ability to maneuver through breaks in the line
3. Detect obstacles and manuever around them
4. Identify colors to be able to locate green and aluminum victims.

Robot arm at this time has been used in major industries. This robot is used to make production more quickly and accurately. But you know that to design a robot arm requires an accurate calculation?

Yes, the robot arm is one of the robots that have a working principle similar to the human arm movement. To design a robot arm is very complex because it requires the cooperation of appropriate motor movement. You should also consider the type and torque of motor and also determine where your motor will attach.

If you will make your own robot arm, it’s good if you are visiting this page ..

I’ve collected some schematic diagrams of sound activation as follow:
