Patlabor (a portmanteau of "patrol" and "labor") refers to Mobile Police Patlabor (機動警察パトレイバー, Kidō keisatsu patoreibā) a manga franchise created by Masami Yūki.
The popular franchise was adapted into a TV series, two OVA series, three feature length movies, and a short film compilation, named Minipato (ミニパト) because of its SD drawing style. These adaptations have been adapted into video games and licensed products from OST to toys. Patlabor is known for using mecha - designed by Yutaka Izubuchi - not just for police or military purposes, but also for industrial and municipal jobs. (Wikipedia)
