Mechonoids
Mechonoids were large spherical robots. They were originally created by humans to help colonise worlds. They were eventually abandoned and forgotten on the planet Mechanus. They were one of the few beings who could prove a match for the Daleks.
These robots were neither good nor evil. They did turn violent when their home planet was threatened. Otherwise, they seemed to be peaceful and open to visitors.
