Robotics is undoubtedly one of the most influential fields of modern technology in changing the very nature of our society. Parallel Delta-robots have for a long time been mainly focused on a niche market but compared to serial anthropomorphic robots they present several simplicity and improved dynamics features. Additive manufacturing and 3D-printing technologies have enabled rapid changes in robotic engineering as we classically know it, allowing for greater creativity and freedom in machine design innovation and maintenance. The effective benefits of far-reaching design freedom in terms of geometry, materials and manufacturing accessibility, are now starting to become apparent, answering many complex technical questions and scientific uncertainties that go beyond basic design and functional knowledge and that require engineering skills and scientific analysis. The Delta robot, as one of the most important industrialized parallel robots because of its simplicity, is considered in this work, covering an overview of multidisciplinary aspects of Delta robots, mechatronics design, interface software and virtualization technologies, and the benchmarking of the new 3D-printed and low-cost SMILE.TECH’s Delta robot Oscar.
