Development, integration and evaluation of a web-based virtual robot task simulator in the teaching of robotics

摘要

A web-based virtual robot task simulator has been developed and used in the teaching of robotics through lab demonstrations and a set of lab assignments. The simulator allows a high degree of real time interaction with a virtual robot that can be commanded to perform a number of pick and place operations on virtual objects replicating an existing industrial robot manipulator. A unique characteristic of the system is that, apart from using high level robot motion commands like the real robot, it allows a simplified graphical input of target positions and orientations to define a gripper path. It also encourages interaction and collaborative problem solving. Empirical evidence shows that the effectiveness of the learning program is increased by the enhanced motivation and interest of the students and through their improved learning capabilities.
