New techniques, like virtual laboratories and the ones remotely operated, improve teaching and learning in the academic society. These allow students to gain experience with real tools, in an intuitive way at a low cost. The paper presents an alternative way of e-learning in robotics that allows the students to simulate and remotely operate the mechanical Rv-2AJ robot arm. The main characteristics of the application are a realistic graphics and a wide variety of options which allow the user to easily learn the advanced concepts of control of the robot.

As the educational system is growing there is a lot of paperwork to do like completing different types of certificates, or traditional gradebook. The paper presents a different approach to facilitate and secure the writing of certificates or traditional gradebooks. This system uses a robot arm, RV-2AJ, which has a pen attached. The setups are easy to be made because they involve the reading of only three points for calibration which forms a right-angled triangle. After the calibration the robotic arm can write even if the writing surface is on an inclined plane, or the paper is rotated. This system is more secure than the one that uses the ink printer, because the movement of the robot arm to reproduce the font on the paper is unique. Another secure element is the embossing stamp. The embossing stamp is created by changing the pen with a needle. The needle creates small closed holes using a pattern in which the information used for writing is encrypted.
