Abstract
Nowadays, robotic manipulators’ uses are broader than industrial needs. They are applied to perform agricultural tasks, consumer services, medical surgeries, among others. The development of new cost-effective robotic arms assumes a prominent position to enable their wide-spread adoption in these application areas. Bearing these ideas in mind, the objective of this paper is twofold. First, introduce the hardware and software architecture and position-control design for a four Degree of Freedom (DoF) manipulator constituted by high-resolution stepper motors and incremental encoders and a cost-effective price. Secondly, to describe the mitigation strategies adopted to lead with the manipulator’s position using incremental encoders during startup and operating modes. The described solution has a maximum circular workspace of 0.7 m and a maximum payload of 3 kg. The developed architecture was tested, inducing the manipulator to perform a square path. Tests prove an accumulative error of 12.4 mm. All the developed code for firmware and ROS drivers was made publicly available.
