The Battlemech Droid, more commonly known as the “Bleep-Bloop” for the sounds it makes, was a 1.75 meter-long droid that had four legs, but often retracted them and used a repulsorlift and two engines. The original Battlemech Droid was a concept by Viper Dermo, an alias of Prophit Delphiki, which was sold to Incom Corporation as a “replacement for the astromech.”
