Before revision: Robotics Bézier curves can be used in robotics to produce trajectories of an end-effector due to the virtue of the control polygon ’s ability to give a clear indication of whether the path is colliding with any nearby obstacle or object .
After revision: Robotics Bézier curves are used in producing trajectories of the end effectorsBecause the control polygon allows to tell whether or not the path collides with any obstacles, .
