Abstract
Systems and methods in accordance with embodiments of the invention implement flexible members that include integrated tools made from metallic glass-based materials. In one embodiment, a structure includes: a flexible member characterized by an elongated geometry and an integrated tool disposed at one end of the elongated geometry; where the flexible member includes a metallic glass-based material.
Claims10
A terrain traversing device comprising:
- a device body;
- at least one rotor element rotatably interconnected with said device body and configured to provide a propulsive force thereto;
- a plurality of elongated flexible members, each having a first end and a second end and formed of a metallic glass-based material having a thickness of less than approximately three times the size of the plastic zone radius of the metallic glass-based material and an elastic limit of at least 1.0%;
- an integrated tool disposed at the first end of each of the elongated flexible members, wherein the integrated tool is at least one hook formed by a bend in the elongated flexible member;
- wherein the elongated flexible member and the integrated tool comprise a unitary body;
- and
- wherein only the second end of each of the elongated flexible members is attached to the at least one rotor element, such that each elongated flexible member is configured to at least partially wrap about the at least one rotor element during operation;
- and
- wherein the plurality of elongated flexible members are distributed around the at least one rotor element such that the aggregate of the plurality of elongated flexible members form an outer wheel of integrated tools about the at least one rotor element.

- a plurality of elongated flexible members, each having a first end and a second end with an integrated tool disposed at the first end, wherein each of the elongated flexible members comprises a unitary body with the integrated tool formed of a metallic glass-based material;
- wherein the metallic glass-based material has a fracture toughness of at least 80 MPa·m1/2, an elastic limit of at least 1.0%, and allows bending by cold working of the elongated flexible member with a thickness of less than approximately three times the size of the plastic zone radius of the respective metallic glass-based material to an angle as small as 80° without compromising the structural integrity of the elongated flexible member;
- wherein the integrated tool is a hook formed by a bend in the elongated flexible member, and wherein the bend forms an angle with the elongated flexible member of greater than 80°;
- and
- wherein only the second end of each of the elongated flexible members is attached to the at least one rotor element, such that each elongated flexible member is configured to at least partially wrap about the at least one rotor element during operation;
- and
- wherein the plurality of elongated flexible members are distributed around the at least one rotor element such that the aggregate of the plurality of elongated flexible members form an outer wheel of integrated tools about the at least one rotor element.
