    • Wrist-Partitioned Inverse Kinematic Accelerations and Manipulator Dynamics 

      Hollerbach, John M.; Sahar, Gideon (1983-04-01)
      An efficient algorithm is presented for the calculation of the inverse kinematic accelerations for a 6 degree-of-freedom manipulator with a spherical wrist. The inverse kinematic calculation is shown to work synergistically ...

    • Understanding Text through Summarization and Analogy 

      Tonfoni, Graziella; Doyle, Richard J. (1983-04-01)
      Understanding a text exactly in the way that the Text Producer meant the text to be understood is highly unlikely unless the text interpretation process is constrained. Specific understanding-directing criteria are ...

    • Determining Attitude of Object from Needle Map Using Extended Gaussian Image 

      Ikeuchi; Katsushi (1983-04-01)
      An extended Gaussian image (EGI) is constructed by mapping the surface normals of an object onto the Gussian sphere. The attitude of an object is greatly constrained by the global distribution of EGI mass over the ...
