- Industrial robotic arm in machining process aimed to 3D objects reconstructionPublication . Zorawski, Matheus; Brito, Thadeu; Lima, José; Silva, Manuel F.Industrial robots are a technology which is highly present in industry and can perform several tasks, namely machining activities. Different than CNC machines, which work with G-code and have available several software applications to generate the machine code, there is a lack of software for robotic arms, in addition to each application depending on its own language and software. This work studied a way to use different robotic arms for 3D part machining processes, to perform 3D objects reconstruction obtained through a low-cost 3D scanner. Dealing with the 3D reconstruction by integrating 3D acquisition and robotic milling with software available on the market, this paper presents a system that acquires and reconstructs a 3D object, in order to seek greater flexibility with lower initial investments and checking the applicability of robot arm in these tasks. For this, a 3D object is scanned and imported to a CAD/CAM software, to generate the machining toolpath, and a software application is used to convert the G-code into robot code. Several experiments were performed, using an ABB IRB 2600 robot arm, and the results of the machining process allowed to validate the G-code conversion and milling process using robotic arms, according to the proposed methodology. © 2021 IEEE.
- Introduction to the special issue “Robotica 2016”Publication . Cunha, Bernardo; Lima, José; Silva, Manuel F.; Leitão, PauloAutonomous robotics has seen its popularity and application in distinct fields, namely in services and industry, increase significantly in the last two decades. Several areas related with robotics have been addressed by the academic community and thus journals and conferences emerged to broadly disseminate the developed knowledge. The IEEE International Conference on Autonomous Robot Systems and Competitions (ICARSC) gathers participants from academia and industry, working in the field of autonomous robot systems and related areas. It is organized since 2001 in parallel to the Portuguese Robotics Open, and aims at exploring and discussing the latest trends in research and technology in the fields of robotics and related areas. The authors of the best papers presented at ICARSC 2016 were invited to submit extended and improved versions of their manuscripts to this “Robotica 2016” special issue.
- Proposal of a low cost educational mobile robot experiment: an approach based on hardware and simulationPublication . Gonçalves, José; Silva, Manuel F.; Costa, Paulo Gomes da; Sousa, ArmandoIn this paper it is presented an educational mobile robotics experiment based on a low cost mobile robot prototype and its simulation. The chosen educational robot challenge is a classical introductory experiment, that consists in following a line with a mobile robot based on the differential kinematics. The presented experiment has as goal to introduce students to the challenges of mobile robotics, initially programming a simulated robot, building a real robot and finally testing the developed code in a real robot. The robot was simulated using SimTwo, which is a realistic simulation software that can support several types of robots. Having as base the proposed challenge, a mobile robot competition was conducted as a part of the evaluation of the curricular unit of ``Systems Based on Micro-Controllers'' of the ``Electrotechnical and Computer Engineering'' course of the Faculty of Engineering of the University of Porto.
