Robot-Crawler: Statically Balanced Gaits

S. Parasuraman, F. J. Hang, M. K. A. Ahamed Khan
2012 International Journal of Advanced Robotic Systems  
This paper presents a new statically balanced walking technique for a robot-crawler. The gait design and the control of the robot crawler aim to achieve stability while walking.  ...  In order to reduce the risk of stability loss while walking, a measure for the robot stability (so-called stability margin) is typically used in the gait and motion planning.  ...  The data captured is then transferred to the Motion Capture Analysis tool which models a 3D view of the object captured.  ...
