In order to strengthen the working stability of camellia fruit picking robot , the research established the mathe-matical model of the mechanical arm of camellia fruit picking robot by using a combination of D -H notation and cylindri-cal coordinates representation ,which was developed by ourselves ,the picking robot arm structure was also analyzed .Fur-ther more , forward kinematics equation of mechanical arm was solved by MATLAB ,which was based on this model , thus simulation wo...
