Abstract
A structure and control system for changing the attitude of an object, such as a spacecraft, is provided. An example attitude control system includes a panel coupled to the object. The panel includes a first panel section coupled to the object by way of a first joint, a second panel section coupled to the first panel by way of a second joint, and a third panel section coupled to the second panel by way of a third joint.
Claims20
A structure for changing an attitude of an object, comprising:
- a panel coupled to the object, wherein the panel is configured to controllably change the attitude of the object, the panel comprising:
- a first panel section coupled to the object by way of a first joint;
- and
- a second panel section coupled to the first panel by way of a second joint.
1 more element
An attitude control system for an object, comprising:
- a body;
- and
- a panel coupled to the body, wherein the panel is configured to controllably change the attitude of the object, wherein the panel extends outwardly from the body, the elongated member comprising:
- a first panel section coupled to the object by way of a first joint;
- and
- a second panel section coupled to the first panel by way of a second joint.
3 more elements
An attitude control system for an object, comprising:
- a body, wherein the body comprises a first joint and a second joint;
- a strain actuator configured to directly actuate the first joint;
- a passive element, wherein the passive element is coupled to the body proximate the second joint, wherein a stiffness of the second joint and at least one characteristic of the passive element are selected so as to provide a non-holonomic trajectory of the object when the strain actuator actuates the first joint.
