The apparatus further comprises at least one sensor secured to one of the frame or the grip adapted to sense an orientation of the pile, a processor means for determining a tool path around the pile and actuators for adjusting the frame during rotation about the pile to maintain the tool holding head along the tool path. The method comprises securing the grip to the pile proximate to a top end thereof, sensing an orientation of the pile, determining a tool path around the pile and rotating a top end of a frame about the pile. |
