Technical Quiz On Robotics and Automation

 Technical Quiz On Robotics and Automation 

Hello Everyone Today I come with a new and interesting quiz competition. It is a Technical Quiz Competition .It is an online quiz competition on Industrial Robotics - Support Systems . In this quiz competition everyone can participate (Faculty Members & Students who are interested in brushing up their knowledge in Robotics).It is being organized by the Robotic Club of the Department of Mechanical Engineering, LBRCE, Mylavaram, Krishna (Dt), Andhra Pradesh, India. There are no registration fee .All the question are asked in this quiz competition based on Robotics Knowledge . There are total 20 MCQ Question's. There is no negative marking. There is no time limit. All the questions are same in this quiz competition. After Quiz Completion Every Participants will receive an E-certificate on successful attempt of this quiz. The passing criterion is 40% for the Quiz. For Participating in this quiz competition first of all click on the quiz link which is given in the bottom of this post. After clicking on the link fill up the correct details name, email id, class, department, college name etc. After Fill up the the registration form you can give the exam and after complete the exam click on the submit button. 

After Submitting Quiz Competition who scoring 40 % or above will receive participating certificate in your email .

After Submitting the quiz competition everyone get this type of certificate.
