Patent number: 8818555Abstract: An apparatus, method and computer-readable medium planning a path of a robot by planning an optimal path while satisfying a dynamic constraint. In a process of searching for a motion path from a start point to a goal point while extending a tree from a start point of a configuration space to generate a path, along which a manipulator of the robot is moved in order to perform a task, an optimal path is generated responsive to the dynamic constraint of the manipulator of the robot to generate stable motion satisfying momentum and Zero Moment Position (ZMP) constraint. Accordingly, path planning performance is improved and a path satisfying a kinematic constraint and a dynamic constraint is rapidly obtained.Type: GrantFiled: October 21, 2010Date of Patent: August 26, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Myung Hee Kim, Bok Man Lim, Kyung Shik Roh, San Lim

Patent number: 8768512Abstract: A robot and a control method thereof. The control method includes generating and storing plural grasping motions corresponding to data of a target object, selecting a grasping motion corresponding to a grasping purpose of the target object among the plural grasping motions, generating a path of arms corresponding to the selected grasping motion, calculating torques to track the path of the arms, and outputting the torques toward the arms so as to perform movement of the arms and grasping of the target object. The grasping motion path corresponding to the grasping purpose is generated and the path of arms is generated, thereby reducing overall calculation time during grasping of the target object to increase calculating efficiency, minimizing generation of the path of the arms, and allowing an arm path calculating process to be performed at the late stage of a grasping control process to improve grasping performance.Type: GrantFiled: December 16, 2011Date of Patent: July 1, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: San Lim, Myung Hee Kim, Kyung Shik Roh, Young Bo Shim, Bok Man Lim

Publication number: 20130330358Abstract: Two vIRF4 (Kaposi's-sarcoma-associated-herpesvirus vIRF4) peptides, vif1, corresponding to aa202-216 of vIRF4, and vif2, corresponding to aa220-236 of vIRF4, are potent and selective HAUSP antagonists. The vif1 and vif2 peptides robustly suppress HAUSP DUB enzymatic activity, ultimately leading to p53-mediated anti-cancer activity. The vif1 and vif2 peptides, along with their homologues, are useful in treating cancer through regulation of p53 activity in a cancer cell. Also disclosed is the crystalline structure of vIRF4-HAUSP TRAF domain complex. The structure is useful in computer aided drug design for identifying an agent that interacts with and inhibits HAUSP, resulting in p53 medicated cell cycle arrest of cancer cells.Type: ApplicationFiled: February 22, 2012Publication date: December 12, 2013Inventors: Jae Jung, Hye-Ra Lee, Myung Hee Kim, Tae-Kwang Oh, Jung-Won Hwang
