The second edition of PASRO - Pascal for Robots includes some new aspects of the PASRO development within the last two years. Besides the PASRO implementation on other computers with the help of different Pascal compilers and operating systems, one significant new development has been the implementation of the PASRO concept in the programming language C. Therefore the second edition is divided into two major parts: A. The revised and little extended "old" PASRO description of the first edition based on Pascal. B. The new PASRO/C description based on C. Of course we know that the name "PASRO/C· is a contradiction in terms, but we chose it, in order to use the well known name PASRO in future. The additional author John Favaro is respon­ sible for the PASRO/C implementation and the des~ription while Christian Blume designed the PASRO concept and implemented the original PASRO, together with Wilfried Jakob. Additional thanks are dedicated to Jan Schloen and Thomas Eppting, who helped us to implement PASRO/C. We would also like to thank all readers of the first edition, who sent us their comments and corrections. Amongst these, spe­ cial thanks to G. Macartney from the Queen's University of Bel­ fast.

Previous works on industrial robots dealt with "programming" and "programming languages" only in passing; no comparison was made between characteristics of the individual programming lan­ guages. This book, therefore, gives a detailed account of industrial robot programming and its environment. Mter introducing basic concepts special attention is paid to the language constructs relevant to robot programming. The features of various elements of the languages ex­ amined are compared. The languages are based on the following concepts: SRL - high-level programming language based on AL with PASCAL elements (University of Karlsruhe, F. R G. ) PASRO - integrated into PASCAL, based on the geometrical data types of SRL (I. I. -BIOMATIC Informatics Institute, Freiburg, F. RG. ) AL - derived from the high-level programming language ALGOL (Stanford University, U. S. A. , and University of Karls­ ruhe, F. RG. ) AML - high-level programming language, influenced by PL/1 (IBM, U. S. A. ) VAL - language specifically developed for robots (Unimation, U. S. A. ) HELP - mixture of high-level language elements and robot l- guage elements and real-time processing (DEA, Italy) SIGLA - a simple machine language (Olivetti, Italy) ROBEX - based on NC programming (Technical College (RWTH), Aachen, F. RG. ) RAIL - high-level programming language for industrial robots with elements for graphic processing (Automatix, U. S. A. ) IRDATA - general software interface between programming and robot controller (Association of German Engineers (VDI), F. R G.
