  Article:   AN AUTONOMOUS APPROACH TO WHEEL CHANGING PROBLEM.

Authors:  ZSUZSANNA MARIAN, MIHAI OLTEAN. 		 
       
         
  Abstract:  We describe a self-repairing robotic car capable of changing its wheels automatically. The robot is constructed from a Lego NXT kit and a Lynx Arm kit which are coordinated from a PC. The difficulty consists in assembling the wheel on its shaft with a high precision which is not possible with the Lego components. This was solved by creating an ensemble made from both wheel and its shaft. The entire ensemble is replaced instead of the wheel alone. We have performed several experiments which show the effectiveness of our approach.

Key words and phrases: robot, car, wheel changing, self-repairing, Lego NXT, Lynx arm.
