Abstract
The present invention relates to a soft robot using diamagnetic levitation. Such a soft robot using diamagnetic levitation is formed of a diamagnetic material to levitate on the ground on which a magnetic field is formed, and moves in a direction toward a predetermined point of a head part when the predetermined point of the head part is heated, and may thus move and change its direction in a state in which it is not in contact with the ground.
Claims11
A soft robot using diamagnetic levitation levitating on the ground on which a magnetic field is formed, comprising:
- a body part formed of a diamagnetic material having a film shape;
- one or more head parts formed of the diamagnetic material and connected to an outer peripheral edge of the body part;
- a plurality of grip parts formed of the diamagnetic material and connected to the outer peripheral edge of the body part;
- and
- a hygroscopic film of which an expansion rate according to absorption of moisture is different from that of the grip part and which is attached to a first surface of each of the grip parts facing the ground or a second surface of each of the grip parts opposite to the first surface,
- wherein when a predetermined point of the head part is heated, magnetic susceptibility of the predetermined point decreases, such that a diamagnetic levitation force of the predetermined point decreases.
