These are Malleabyte Robots (built in the 23rd century) or M-Bots for short.

The sphere bot is designed as security cameras and equipped with stunners.

The other bots are built for maintaining machinery and equipment (along side with Malleabyte Maintenance Crew) or as robot pilot for ships on long journeys.

These bots are made from steel and titanium and have programmes to obey people and follow instructions.
