| Summary: | 碩士 === 國立交通大學 === 機械工程學系 === 99 === The more field goals you get, the more points you get. If
you get many points with strong defense, you will have great
opportunities to win the game. There are three ways to get field goals: jump-shooting, layup, and dunk. This thesis discusses the arm’s movement of jump-shooting. We can realize standard basketball shooting movement by consulting some references. But there seem to be four kinds of standard shooting movement which have little differences. In order to find out which movement is the most standard, I use SolidWorks to construct a human model and then use COSMOSMotion to do dynamic simulation of these four shooting movement. The shooting movement which makes the ball producing least deviation in simulation is the most standard shooting movement. Then I base on the most standard movement and use three position synthesis of mechanism synthesis to design an orthosis that can lead arms to do the same movement. In order to verify whether this orthosis works, I use SolidWorks to construct the orthosis model. Then I combine the orthosis model with human model, and I use COSMOSMotion to simulate basketball shooting. In the end, we can know from the result of simulation that the arm’s movement is corrected and the deviation of the ball is smaller than the human model
without orthosis.
