Due to the space is limited, so this letter is a simple introduction to my projects. Actually, even though scratch any project report of mine, it usually needs more than a hundred papers to printout. So, if you interest in any project, please feel free to contact me for more information.

1.1 Kinematics New-style apparatus Design and Implement

(Captured 2003)

This instrument is the first one of my Kinematics Instruments Sequence. The goal of this project is to design a prototype based on the Laser Triangular Method for the displacement-time measurement. The technological accumulation of this project is significance for next research project that was described in next section. 1.2 Classical Kinematics High-speed Graphic Analysis Platform

(Captured 2004)

acceleration (Captured 2004)

This instrument is a new generation based on above one. The measurement method is also adopt Laser Triangular Method but with powerful automatic analysis features on Upper Computer.

Upper Software for Dreamer robotic system Dreamer robotic system is the most interdisciplinary personal project I have done. The research aspects of this project cover Embedded Operating System Design and Implement, Sensors, Machine Vision, Machine Learning, Computer graphical, Human Computer Interaction and more. 1.4 Vanessa Embedded Operating System

(Block Diagram of Vanessa Real-time Embedded Operating system)

Temperature results were shown in the Command Shell of Vanessa (Captured 2007)

This is a demo project for Vanessa Operating system evaluating and the purpose of this project is to implement a thermograph using the least cost. 1.4.2 Stepper motor experiment

(Captured 2007)

This is the second demo project for Vanessa Operating system evaluating and it is also the simplest one of all demos. The purpose of this project is to control a stepper motor via Terminal.

Generated Signal (Captured 2007)

This is the third demo project for Vanessa Operating system evaluating. The purpose of this project is to design a low cost frequency generator for analogy electronics experiment. Key Features: 1. The frequency of output signal: 4Hz - 2Mhz 2. The output voltage range of output signal: 0v - 5v 3. The duty cycle of output signal: 1% - 99% 4. The information of output signal is shown on LCD 5. Low cost

Practical Example 1: Description: In this case, we let electrical car running with full power support until it out of raceway. During this process we sample data of webcam (named Actual xxx) and milometer (Named Ideal xxx) per 20ms (sample interval).

Kinematic Model:

Practical Example 2: Description: In this case, we let electrical car running forward with full power support, in the first 0.9s, then make it backward with full power support, in the following 0.4s.

Kinematic Model:

If you need to design a project that adopts High-Speed robots to do some strict operations, what will you do at first? Bingo! Find the Accurate Kinematic Model of the robot. This project is designed to find Accurate Kinematic Model, automatically.

1.6 Speech Enhance ASIC

Prototype System for Functional Verification (Captured 2008)

This project is being researched. More details will be brought to you in the next letter. 2. Funds All above projects were sustained by my own funds. In other words, I have taken part in a lot of commercial projects to exchange enough money for my own projects. Although this is a hard way but I have seen more landscapes than peers and I do enjoy it. Through this process, I have seen who I want to be and what I should do clearly.

Some Experimental Elements and Instruments in My Workroom (Captured 2008) I am proud to tell you that my research workroom is sustained by my own funds. Maybe my workroom is simple and crude in your eyes but it is the top personal research workroom in my community. BingHao September 10, 2008 2:27AM
