Engineering education has benefited from the introduction of advanced technology, allowing students to learn essential Science, Technology, Engineering, and Mathematics concepts through hands-on experiences. Robotic kits have been used as an educational device in several academic fields, and they have been readily accepted and adopted. However, the majority of the time, such kitsu2019 knowledge level requires the student to have basic concepts that are not always appropriate for the student. The Cartesian Coordinate System, an essential component of engineering, is a key concept in engineering, from graphing to data processing in robotics and control applications, and beyond. This paper discusses the creation and use of a new Two-Dimensional Coordinate System Educational Toolkit to teach the two-dimensional representations as the first step to develop spatial thinking. The Educational Mechatronics Conceptual Framework supports knowledge acquisition in concrete, graph, and abstract forms.

The ability to work with and apply mathematical and physical principles across Cartesian and non-Cartesian coordinate systems is an essential ingredient in higher-division physics curricula's success. Although limited in scope, early investigations into student integration of coordinate systems has revealed that students have a lot of trouble. This paper will revisit our recently identified student resource clusters for unit vectors. In non-Cartesian coordinate systems, we also find additional resources that shed further light on students'u2019's understanding of position vectors and velocity vectors.

The automatic testing system and sorting system based on the enterprise's production environment are tested and developed in order to satisfy a particular company's medium and small scale production of the slide valve body of OCV and its specific process requirements. Secondly, the test description is further enhanced by analyzing and interpreting the product's test specifications in detail, and the automated testing system and test procedure are developed.

The Internet of Things (IoT) is essential for the educational transition from physical and virtual environments. This paper explores how to convert it from IoT technology in the Two-Dimensional Cartesian Coordinate System Educational Toolkit to MEIoT 2D-CACSET, which includes educational mechatronics and the IoT. The Educational Mechatronics Conceptual Framework has been expanded to include knowledge construction in virtual concrete, virtual graphic, and virtual abstract levels. Using the MEIoT 2D-CACSET to learn about coordinate axes, quadrants, and a point in the 2D Coordinate Cartesian System, three instructional designs were created for this project.

For high-quality data fusion using different coordinate systems, a high-precision coordinate conversion is essential. The transformation precision is mainly determined by the conversion precision, the root mean square error of the conversion of common points, or the conversion of check points, according to the RMSE of the conversion of check points. Second, the RMSE of the conversion of check points may not be consistent with the RMSE of the conversion of common points, meaning that the RMSE of the conversion of common points should not be used as a transformation precision indicator.

The fruit fly, 'Drosophila melanogaster,' continues to be one of the most commonly used model organisms in biomedical research. To maintain their fly stock, fly production facilities typically have to produce thousands vials of fly food each week. A cartesian coordinate robot is linked to a peristaltic pump in this system. The robot's build is based on an open hardware CNC router and uses belt and pulley actuators for the X and Y axes, as well as a leadcrew actuator for the Z axis. To Grbl, a Raspberry Pi is used to produce and stream G-code instructions. A touch screen on the Raspberry Pi provides a graphical user interface to the device. Although the robot was specifically designed for the purpose of filling vials of fly food, it could also be used for other liquid handling tasks in the laboratory.

This paper discusses how bend processing can be more cost-effective and precise, as well as a prototype of a six-axis Cartesian coordinate robot for sheet metal bending, which could be used to replace labor finishing automatic bending procedures. In addition, the robot's dynamic results are analyzed, and design optimization is carried out. The flexible configuration of the six-axis Cartesian coordinate robot for sheet metal bending robot developed in this paper is shown to be adaptable to sheet metal bending robots and increases the durability of sheet metal bend robots.
