  • Publication number: 20230330841
    Abstract: A method of making a magnetic miniature robot includes: rotationally deforming a segment of material about a rotational deformation axis, from an initial shape to a deformed shape, the material including a plurality of magnetic particles distributed in an elastic matrix; magnetizing the plurality of magnetic particles in the segment to form a magnetized segment in a magnetization process, in the magnetized segment in the deformed shape being characterized by a uniform magnetization profile; after the magnetization process, enabling the magnetized segment to elastically recover the initial shape and form a non-uniform magnetization profile; and coupling together at least one pair of the segment to form a main component, wherein the non-uniform magnetization profiles of the at least one pair of the segment are disposed in opposing orientations to configure the main component with a zero net magnetic moment about a sixth degree-of-freedom axis.

  • Patent number: 10675718
    Abstract: A method for reversibly attaching a phase changing metal to an object, the method comprising the steps of: providing a substrate having at least one surface at which the phase changing metal is attached, heating the phase changing metal above a phase changing temperature at which the phase changing metal changes its phase from solid to liquid, bringing the phase changing metal, when the phase changing metal is in the liquid phase or before the phase changing metal is brought into the liquid phase, into contact with the object, permitting the phase changing metal to cool below the phase changing temperature, whereby the phase changing metal becomes solid and the object and the phase changing metal become attached to each other, reheating the phase changing metal above the phase changing temperature to liquefy the phase changing metal, and removing the substrate from the object, with the phase changing metal separating from the object and remaining with the substrate.
