Power source - some robots use electric motors, others use hydraulic actuators.

If you use actuators, the material themselves aren't programmed to a shape but the design of the material.

The majority of delta robots use rotary actuators.

Minolta also uses piezoelectric actuators rather than conventional motors to move the chip around.

To achieve the same effect as human motion, humanoid robots use mainly rotary actuators.

It could be opened using hydraulic actuators to load large items quickly.

However, the Japanese version uses linear-inductive actuators instead of three hydraulic rams.

Since the arm uses strings and actuators, no motors were used at the joints.

Another way of producing tactile sound uses "linear actuators", which move furniture (usually up and down), rather than shaking it.

The ball is directly controlled using actuators, whereas the body has no direct control.
