Robotics is a science, which aims at controlling mechanical systems through electrical systems and computer techniques. Robotics has a high rate of applicability but, in order to make it easier to comprehend when it comes to learning processes, methodologies that enhance the student's performance and learning curve, like the project-based learning method, are indispensable. The project-based learning technique diverges from the conventional approach, as it makes the many students the object itself of their learning development, by giving them the power of choice and major control over the entire process. This article aims at presenting the project developed by students from the “Robotics and Its Elements” class ministered at Universidade Federal de Ouro Preto - UFOP. The project dealt with concepts, approaches, explanations, and techniques that created a robot-cell (Melfa RV-2AJ and its peripherals) which used the ROS framework system alongside computer vision resources. The robot, after its completion, was able to perform repetitive tasks such as the detection and gathering of specific physical elements – it can manipulate them properly. To make those tasks possible, a Kinect camera was used to obtain data such as the depth and location of the elements which were in the robot's range of grasp. In addition, a detection mechanism derived from the combination of an open source graphic library called OpenCV with the usage of the HSV color system was an important accessory, so that color calibration and orientation addressed properly. Finally, the designated framework (ROS) suited to establish a connection between the robot and its whole operational environment, in order to make the data-sharing and input signal both able to work over the robot's mobility.

“…Crainic and Preitl [27]utilize TeamViewer in a remote laboratory where the control of a robotic arm is practiced. The laboratory equipment integrates an RV-2AJ robotic arm (Mitsubishi Co.), a CR1-571 controller, a compressor with a minimum pressure of 8 bars, a computer as a server where TeamViewer is installed on and a camera for observing the experiment.…”

Abstract-Laboratory is a key element of engineering and applied sciences educational systems. With the development of Internet and connecting IT technologies, the appearance of remote laboratories was inevitable. Virtual laboratories are also available; they place the experiment in a simulated environment. However, this writing focuses on remote experiments not virtual ones. From the students' point of view, it is a great help not only for those enrolling in distant or online courses but also for those studying in a more traditional way. With the spread of smart, portable devices capable of connection to the internet, students can expand or restructure time spent on studying. This is a huge help to them and also allows them to individually divide their time up, to learn how to self-study. This independent approach can prepare them for working environments. It offers flexibility and convenience to the students. From the universities' point of view, it helps reduce maintenance costs and universities can share experiments which also helps the not so well-resourced educational facilities.

This article describes a contribution to the field of telerobotics via the Internet through the development of a web-based platform allowing the remote control of robots by multiple users, simultaneously. It also deals with minimizing the execution times of tasks by reducing connection and interaction delays. For this purpose, the Web Real-Time Communication ( WebRTC ) technology is utilized. The developed remote manipulation system allows the operators to visualize the robot, its surroundings and the data incoming from its sensors, and to carry out basic tasks, either independently by the manipulator or by the mobile robot, or jointly by both mechanical sub-systems. In addition, to ensure the control of the remote robot by several operators simultaneously, a priority system managing parallel tasks and a chat system between the operators have been proposed. Besides, many teams are able to exploit the robot, concurrently. The WebRTC-based Multiple Operator Single Robot ( MOSR ) telerobotic platform is validated on the emulator of the RobuTER/ULM mobile manipulator through various scenarios of primitive tasks over the Internet.
