US Patent 10058996 Robot adaptive placement system with end-effector position estimation

A method including, based at least partially upon a command transmission to at least one motor of a robot, estimating deflection for at least one member of the robot during movement of the robot; based at least partially upon the estimated deflection, determining calculated end effector coordinates for an end effector of the robot; and based at least partially upon the calculated end effector coordinates, adjusting movement of the robot for placing a substrate, located on the robot, at a desired location.
