Long-running PD library, the third to be established after WACCI and DW Software, and run by Richard Fairhurst. Robot started off with cassette-only software but soon moved to disc operation. Among its features were a wide range of software (AMSDOS-based and CP/M, UK and European), eventually numbering around 200 'sides' in total; many original programs, such as PowerPage; and sometimes appallingly slow delivery. Robot was often at the centre of the so-called 'PD wars', along with Scull PD.
