ANDROTEXT for HERO 1 Editor and Compiler IBM PC USER'S GUIDE
Abstract: ANDROTEXT is a language to make communicating with robots easy for everyone. It is a high-level language, which means two things: (1) it is human oriented and can be understood with little technical knowledge; and (2) the same program will work on many different types of robots with minimal modification. ANDROTEXT is rapidly becoming the standard high-level language of the personal robot industry. You can be assured that the programs you write in ANDROTEXT will be useable with robots many generations from now.
