The purpose of this project was to create a model of a robotic arm with 4-DOF equipped with a gripper that is able to move an object to a predetermined area. This thesis investigated the robotic arm’s accuracy by repeating the same predetermined movement and measure the error. The error was measured based on the objects displacement from the target area after a series of repeated movements by the arm. After constructing the robotic arm, an experiment was set up to measure the accuracy and repeatability of the arm. The robot achieved 2.506 mm to 0.922 mm for accuracy and 5.995 mm to 4.059 mm for repeatability depending on speed.Syftet med detta projekt var att skapa en modell av en robotarm med 4 frihetsgrader och en klo för att kunna flytta...
