Thanos has designed several different types of robotic drones to serve his needs. These drones carry out many functions, including maintenance, manual labor, record-keeping, and security. These robots come in many shapes and sizes dependent on their purpose.
a.k.a. Time Probe.
Thanos has access to his own fleet of starships which have included:
Space Throne, Sanctuary, Dreadnaught-666, Demeter
An experimental weapon capable of generating a cube of pure force, which envelops the target and places them into near-complete physical stasis. This stasis cube was capable of holding the insane, power-gem enhanced Thunder-God Thor. The experimental version of this weapon carried charge enough for only one blast.
Infinity Gauntlet (previously)
A gauntlet specifically designed to hold the Infinity Gems. With this item, he is nigh omnipotent.
Space Gem, Soul Gem, Reality Gem, Power Gem, Time Gem, Mind Gem
