Abstract
A microrobot including a propulsion system with a propulsion structure deformable in elongation/contraction along a main axis, an actuator or actuation zone configured to actuate sequentially elongation/contraction cycles of the propulsion structure, a light source aimed at, when activated, emitting at least one predetermined light signal, and a remote control unit. The light source includes an optical fiber, and is configured to be activated by the remote control unit, and the actuator or actuation zone is configured to be activated by the light signal emitted from the light source.
Claims15
A microrobot configured to move in a viscous or viscoelastic navigation material, the microrobot comprising:
- a head portion and a rear portion, and
- a propulsion system, wherein the propulsion system comprises:
- a propulsion structure comprising a deformable portion connecting the head portion and the rear portion, the deformable portion being deformable in elongation and contraction along a main axis connecting the head portion and the rear portion,
- an actuator or actuation zone configured to actuate sequentially elongation and contraction cycles of the deformable portion,
- a light source aimed at, when activated, emitting at least one predetermined light signal, and
- a remote control unit,
- wherein:
- the light source comprises an optical fiber,
- the light source is configured to be activated by the remote control unit, and
- the actuator or actuation zone is configured to be activated by the light signal emitted from the light source, the light signal thus actuating sequentially elongation and contraction cycles of the deformable portion, the microrobot being thus driven by light propulsion.
