Servicer robots used by the Osirians, which probably inspired the Ancient Egyptians to wrap their dead up in bandages. Sutekh used these servicer robots to help build a rocket.

The rocket contained a missile which would destroy the pyramid on Mars, freeing him from centuries of immobility.

The Doctor disguised himself as a mummy in order to place a box of gelignite on the rocket. Sarah Jane Smith detonated the gelignite and blew the missile to pieces.

The pyramid on Mars, containing the Eye of Horus, was guarded by golden servicer robots. All the robots were destroyed when the Eye of Horus was smashed by one of Sutekh's servicers.
