In the present study we attempt to induce a quadruped robot to walk dynamically on irregular terrain and run on at terrain by using a nervous system model. For dynamic walking on irregular terrain, we employ a control system involving a neural oscillator network, a stretch re ex and a exor re ex. Stable dynamic walking when obstructions to swinging legs are present is made possible by the exor ...

A quadtree-based triangulation, sometimes called an RTIN, is a common hierarchical representation of terrain for 3D visualization. In this paper we focus on the memory/error bound trade-offs for using RTINs with planar and quadratic surface patches over triangles.

Many people experience vibration effects on whole-body throughout their lives frequently. Vibrating energy absorbed is exposed all-body caused with vibration hazard in the vertically on body and biodynamic responses from body in speed 2.37 to 5.14 m/s could captivate with car seat on user body, so the vibration energy transferred to a seated people body. In this paper, the human body is modeled...

This paper describes pertinent digital terrain model data structures, namely, grid/raster, quadtree, and triangular irregular network. A basic concept of DIM data structure is also explained. The aspects of TIN storage, TIN data structure conversion, advantages and disadvantages of each structure are discussed. A complete data structure conversion program is also presented. n. 1.0 INTRODUCTION ...
