A direct-drive robot of a comparatively large size has been developed for practical applications in industry, such as laser cutting. It was designed based on the semi-direct-drive concept, and has 5 degrees of freedom with a 700 mm-long shoulder arm, and a 1050 mm-long forearm, covering a working range as large as a car body.<BR>In this paper, control strategies for the full scale model are proposed through basic analysis. Unfavorable behavior of the arm due to its flexibility was supressed by using the pole-cancellation to obtain high servo-stiffness of the arm. Furthermore, feedforward control was applied to a conventional controller to practically remove its tracking-error.
