This document describes a project to design an autonomous manipulator to sort balls by weight using a SCARA robot. The manipulator will pick up balls from a specified area, weigh each one, and sort it into the corresponding tray based on its weight range. A Toshiba TH550 SCARA manipulator was selected for its circular work envelope, selective compliance, flexibility in the horizontal plane, and suitability for point-to-point movements. The specifications of the balls, manipulator dimensions, and end effector are provided.
