The design and application of IRobotQ3D for simulating robotics experiments in K‐12 education

Abstract

AbstractThis study developed a robotic online simulation platform (i.e., IRobotQ3D) for K‐12 education, which realized several main fundamental functions, such as the three‐dimensional (3D) structure design of the robot, a combination of components, graphical programming, and motion simulation. Based on the PhysX physics engine, this system regarded the robot and interactive environment as a rigid body and simplified the robot dynamics, so that ordinary users don't have to care about the complex dynamic problems. In particular, graphical and modular programming modes were adopted, which greatly facilitates the development of robotic learning for K‐12 students. Students can use the IRobotQ3D software on the computer to build virtual robots and simulation environments, write and debug programs to run the operation of physical robots in the simulation window. The technical route of building simulation design function for each physical robot in a 3D environment was determined, and the four‐stage iteration design process was described in detail. Then the steps of applying IRobotQ3D in robotics education were introduced and an experiment was conducted. Forty‐four first‐year junior high school students participated in the experiment. Results indicated that IRobotQ3D plays a positive role in improving students' programming ability, learning attitude, and learning engagement, and demonstrates great educational potential. Finally, the educational value of IRobotQ3D was discussed.
