Abstract

Rotation mechanisms for rotating a payload in two, first and second degrees of freedom (DOF), comprising a static base, a first rotation arm coupled mechanically to the static base through a first rotation joint and used for rotating the payload relative to the static base around a first rotation axis that passes through the first rotation joint, a second rotation arm coupled mechanically to the static base through a second rotation joint and used for rotating the payload relative to the static base around a second rotation axis that passes through the second rotation joint, and a follower member rigidly coupled to the payload and arranged to keep a constant distance from the second rotation arm, wherein the rotation of the first arm rotates the payload around the first DOF and the rotation of the second arm rotate the payload around the second DOF.

Claims12

Dependent claims

A rotation mechanism for rotating a payload in two, first and second degrees of freedom (DOF), the rotation mechanism comprising:

the payload,
a static base,
a first rotation arm having a proximal end and a distal end, wherein the proximal end is coupled mechanically to the static base only through a first rotation arm joint and used for rotating the payload relative to the static base around a first rotation axis that passes through the first rotation arm joint,
a second rotation arm, wherein the second rotation arm is coupled mechanically to the static base only through a second rotation arm joint and used for rotating the payload relative to the static base around a second rotation axis that passes through the second rotation arm joint, and
a magnetic follower rigidly coupled to the payload and magnetically coupled to the second rotation arm,
wherein rotation of the first arm rotates the payload around the first DOF, and wherein rotation of the second arm rotates the payload around the second DOF.
