Secure handwriting using a robot arm for educational purpose

Abstract

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.

A Partitioning Algorithm for Extracting Movement Epochs from Robot-Derived Kinematic Data

“…While we make no assumption about the intent of the robot manufacturer and it would be unusual for a technology to be described with the level of granularity that it's process for file writing is full detailed, there are many products that suggest that they are, or could be, programmed to write out data based on target presentation (Hogan et al, 1995;Lockery et al, 2011;Csaba, 2013;Crainic et al, 2014) and note that this is so in our own device, for which four identical robots were purchased from the same entity, for use in a multi-site clinical trial. Furthermore, we assume that the end-user would prefer the data be partitioned into movement epochs, not strictly by target achievement; as seen in Figure 1, these two criteria may yield two different datasets.…”
