18 Analysis of the straw robot arms in the competition

19 There are some good models below

20 1)http://www.ied.edu.hk/has/phys/mathmechhttp://www.ied.edu.hk/has/phys/mathmech This website highlights the Mathematics for mechanics. 2) This website shows some examples of s traw robotic arms. All of the information are very helpful for us to design the robotic arm. 3) log.hkedcity.net/physicsc/mechanics/mechanics_main.shtmlhttp://data- log.hkedcity.net/physicsc/mechanics/mechanics_main.shtml The website describes something about the mechanics. Internet and Literature reviews

21 工場幾何三角學 (CHAPTER 1.4, 2.6,3.7) 理論力學與機械原理 (CHAPTER 3.2~3.4,5.1~5.3)

22 Self Reflection Advantages of our prototype 1) good look 2) creative idea 3) proper size Disadvantages of our prototype 1) weak bending strength 2) cannot hold the bottle firmly 3) poor craftsmanship at straw joints

23 Our new design

24 Knowledge and skill gained 1.Know how to share duties for the project 2.Learn more about the engineering material and mechanism 3.Synthesis skills to make a robotic arm 4.Know something about the City University of Hong Kong 5.Apply the PowerPoint techniques to do oral presentation 6.Apply the digital image processing skills for the written report It should be a good opportunity to learn something about the material science and mechanism. The knowledge and skills gained are summarised below :
