Robotic Observatories: A Handbook of Remote-Access Personal-Computer Astronomy
Russell M. Genet and  Donald S. Hayes
A classic – occasionally available on Amazon 

Robotic Observatories introduces the history, basic concepts, and future potential of robotic observatories, as well as the stories of pioneer builders and users.  It recounts what working APT (automatic photoelectric telescopes) have done and can do, how any astronomer can operate a robotic observatory using the Automated Telescope Instruction Set (ATIS) telescope command language, and what the functional blocks of an automatic telescope system are.  Finally, it details the hardware and engineering particulars of automatic telescope systems, and covers the software of robot observatory operations, from programming in the ATIS control language to reducing photoelectric observations.
