One of the most persistent designs in robotics is the humanoid. Mimicking humanity was the most obvious path to development for many early efforts in the field. As a result, many of the most successful robot designs have been humanoid in form.
After the Third Robot War, the Planetary League adopted the Rubric of Duty into law, officially confining all commercially produced robots and AIs to a single specialized purpose, effectively preventing them from achieving general intelligence. Even with this regulatory regime, general-purpose hardware remained popular, and many programmers and DIY enthusiasts (on both sides of the law) continually sought to push the boundaries of ability.
For example, the Pegasus Cybernetics S-series, which first saw production in GSC 54 was widely popular, and was adapted to a wide variety of tasks.
