Robotics course is a very common and important course for electrical and mechanical engineering students. It is also a crucial course in the curriculum of mechatronic program which is becoming popular in many North America Universities. Robot itself is a perfect example of mechatronic system. Due to the complexity of the subject, teaching of robotics has always been challenging to instructors and at the same time, learning of robotics has always been a daunting task to students. Hand-on exercises are highly appreciated by students. Institutions with adequate funding are able to provide students hands-on experience through labs1. More recently, more sophisticated virtual lab environments were created based on various real robots2,3,4. There are many benefits of these virtual lab environments such as reducing the maintenance cost due to mishandling, providing flexibilities, collaborations in finishing the lab-Robotics course is a very common and important course for electrical and mechanical engineering students.　It is also a crucial course in the curriculum of mechatronic program which is becoming popular in many North America Universities.　Robot itself is a perfect example of mechatronic system.　Due to the complexity of the subject, teaching of robotics has always been challenging to instructors and at the same time, learning of robotics has always been a daunting task to students.　Hand-on exercises are highly appreciated by students.　Institutions with adequate funding are able to provide students hands-on experience through labs1.　More recently, more sophisticated virtual lab environments were created based on various real robots2,3,4.　There are many benefits of these virtual lab environments such as reducing the maintenance cost due to mishandling, providing flexibilities, collaborations in finishing the lab
