SUMMARYJoint flexibility introduces additional degrees of freedom and vibration modes, thus limiting the performance of the manipulator. To improve control bandwidth, this paper proposes an enhanced two-stage state feedback (SFB) controller, which co

Most industrial serial robots use decentralized joint controllers assuming rigid body dynamics. To prevent exciting the flexible mode, gains are kept low, resulting in poor control bandwidth and disturbance rejection. In this paper, a two-stage flexi

There are hundreds of parallel robot designs, of these, some are suitable for fast material transfer operations, others for precision positioning, or like Fanuc's hexapod, for withstanding heavy payloads. Unfortunately, few machining applications usi
