Abstract
In a method of operating a movable object, in which the movable object includes two or more wheels at least spaced apart from one another in a forward/rearward direction, and two or more eccentric drive parts are each respectively configured to connect a wheel and the body part, the two or more eccentric drive parts can be controlled so that an angle defined between the body part and a ground surface is minimized in a range in which the second side is positioned within the rotatable angle by which the second side is rotatable about the first side.
Claims20
A movable object comprising:
- a body part;
- wheels provided at one side of the body part;
- and
- eccentric drive parts, wherein each of the eccentric drive parts is configured to connect a given wheel of the wheels and the body part and wherein each of the eccentric drive parts is configured to change a relative position between the given wheel and the body part,
- wherein each of the eccentric drive parts comprises a connection member having a first side rotatably coupled to the given wheel, and having a second side rotatably coupled to the body part;
- and
- wherein each of the eccentric drive parts is configured to operate so that a rotatable angle by which the second side is rotatable about the first side is restricted within a selected range.
A method of operating a movable object that comprises a body part,
- a plurality of wheels spaced apart from one another in a forward/rearward direction, and a plurality of eccentric drive parts, each eccentric drive part being configured to connect an associated wheel and the body part, wherein each of the eccentric drive parts comprises a connection member having a first side rotatably coupled to the given wheel and having a second side rotatably coupled to the body part, the method comprising:
- controlling the eccentric drive parts to change a relative position between the associated wheel and the body part so that an angle defined between the body part and a ground surface is minimized in a range in which the second side is positioned within a rotatable angle by which the second side is rotatable about the first side, the rotatable angle being restricted within a selected range.
A method of operating a movable object, the method comprising controlling a first connection member and a second connection member, wherein the movable object comprises the first connection member, the second connection member, a first wheel, a second wheel, and a body part, to control a body height of the body part relative to a ground surface and to control a body angle of the body part relative to the ground surface,
- wherein a first-connection-member first side of the first connection member is rotatably coupled to the first wheel,
- wherein a first-connection-member second side of the first connection member is rotatably coupled to a body-part first side of the body part,
- wherein a second-connection-member first side of the second connection member is rotatably coupled to the second wheel,
- wherein a second-connection-member second side of the second connection member is rotatably coupled to a body-part second side of the body part, and
- wherein the controlling of the first connection member and the second connection member comprises maintaining the first-connection-member second side of the first connection member and the second-connection-member second side of the second connection member to be located between the first-connection-member first side of the first connection member and the second-connection-member first side of the second connection member.
