  • Summary

    Artificial life research is mainly a scientific activity, but it also raises and illuminates certain philosophical questions. This chapter explains what artificial life is and how it is connected with artificial intelligence (AI). It briefly describes some of its representative scientific achievements. Some soft artificial life models focus on self-organization and study how structure can emerge from unstructured ensembles of initial conditions. The chapter discusses some associated philosophical issues involving emergence, creative evolution, the nature of life, the connection between life and mind, and the social and ethical implications of creating life from scratch. The science and engineering of artificial life impinges on a number of broad philosophical issues, including how life emerges from non-life, whether the evolution of life has a directional arrow, what life is, whether software systems could ever be literally alive, and what the social and ethical implications of creating artificial life are.

  • Optimal Robot Motion Planning and Work-Cell Layout Design

  • This paper describes an interactive software system, developed at the Robotics and Automation Laboratory at UCLA to demonstrate innovative approaches to off-line robot programming and work-cell layout design. The software computes the time-optimal motions along specified paths, local optimal paths around an initial guess, and the global optimal path between given end-points. It considers the full robot dynamics, actuator constraints, on the payload acceleration or the gripping force, and any number of polygonal obstacles of any shape. The graphic displays provide a useful tool for interactive motion planning and workcell design.
