Input shaping on a lightweight gantry robot

This video shows an industrial application by CAMotion, Inc. of input command shaping to cancel modes of vibration of a large, lightweight gantry robot, designated the LDP, carrying a heavy “log” of printed paper to a conveyor. The method has been patented (D.P. Magee, W.J. Book: Optimal Arbitrary Time-delay (OAT) Filter and Method to Minimize Unwanted System Dynamics, US Patent 6078844 (2000)). This commercial robot is the one depicted also in Fig. 11.13. Its successor is marketed by PaR Systems, Inc. Reference: D.P. Magee, W.J.
