Robot manipulators are commonly used in today's industrial applications. In this report a 3D-printed anthropomorphic robot arm with three degrees of freedom was constructed. The robot arm operates with the use of a microcontroller and servomotors. Through utilizing the Denavit-Hartenberg method and inverse kinematics the robot’s end effector is able to reach a specified point in space. This report has found that the accuracy of the constructed robotic manipulator reaching a specific coordinate depends on the distance of the end effector from its base. The relative error of the constructed robot’s positioning falls within 1.3- 6.9%, with a 99% confidence. / Robotmanipulatorer är idag vanligt förekommande i industriella applikationer. I denna rapport konstrueras en 3D-printad antropomorf robotarm med tre frihetsgrader. Robotarmen styrs med hjälp av en mikrokontroller och servomotorer. Baserat på DenavitHartenberg metoden och inverskinematik kan robotens ändpunkt ta sig till en specificerad punkt i rummet. Vidare har rapporten funnit att den konstruerade robotens exakthet beror på avståndet emellan robotens manipulator och dess bas. Det relativa felet av robotens positionering ligger inom intervallet 1.3-6.9% med en 99% konfidens.
