The document discusses the design of a prototype robot for grazing rubber trees. It aims to design the prototype with suitable materials and compare the designs to choose the best one. The experiment considers the equilibrium of a multi-part model of the robot in the x-y plane. Variables for each part are specified and forces are calculated for point A based on the weights of parts M1 through M7. Two initial models are analyzed and the results suggest that Model 3 is best as it details the dual-bladed design where each blade grazes the trees by running into one another.
