Robo-tographer : A Remote-Controlled Camera Gimbal

Abstract: This report aims to evaluate a wirelessly controlled robotic arm mounted on a 3-wheel platform that would act as a stabilized camera gimbal. The evaluation is focused on doing experiments to determine the accuracy and repeatability of the robotic arm and to examine if the arm can self-stabilize. Evaluation of the robot was done by 3D-printing a prototype and running experiments using a laser module attached to the robotic arm and measuring the error between the actual obtained points and the target points. The experiments were done on three iterations of the prototype where small changes have been done to the software and hardware components which in the last iteration gave an accuracy of 0,21mm and repeatability of 3,508mm. Stabilization was also achieved with a range of +/- 60 degrees in 3 orientations, roll, pitch and yaw.
