Abstract
An example apparatus includes a planar five bar linkage having a ground link and an endpoint. A feed horn is attached at or near the endpoint of the planar five bar linkage. A first motor is attached to a first side of the ground link to move the endpoint and a second motor attached to the second side of the ground link to move the endpoint.
Claims17
An apparatus comprising:
- a planar five bar linkage having a ground link, a first bar, a second bar, a third bar, a fourth bar and an endpoint;
- a feed horn attached to the endpoint of the planar five bar linkage;
- a first motor attached to a first side of the ground link to move the endpoint, the first bar extending from the first motor, the second bar extending between the first bar and the endpoint, the first bar coupled to the second bar by a first hinge;
- and
- a second motor attached to a second side of the ground link to move the endpoint, the third bar extending from the second motor, the fourth bar extending between the third bar and the endpoint, the third bar coupled to the fourth bar by a second hinge and the second bar coupled to the fourth bar by a third hinge.
