Abstract
A motion mechanism is described. In one embodiment, the motion mechanism includes a base portion, a flexure portion, and a transducer. The flexure portion includes a payload support portion configured to support a payload, a first plurality of elongated portions extending substantially in a first direction and contacting the payload support portion, wherein the flexure portion contacts the base portion. The transducer is arranged to provide a force to the payload support portion in a second direction when actuated, the second direction substantially orthogonal to the first direction. Other embodiments of the motion mechanism are also described.

A motion mechanism comprising:
- a payload support portion configured to support a payload;
- a ground portion;
- a first side portion connected to the payload support portion at a first contact point and connected to the ground portion at a second contact point;
- a second side portion connected to the payload support portion at a third contact point and connected to the ground portion at a fourth contact point;
- a first transducer arranged to provide a force to the first side portion in a first linear direction when actuated so that the first side portion provides a force to the payload support portion at the first contact point in a second direction substantially orthogonal to the-first direction;
- and
- a second transducer arranged to provide a force to the second side portion in a third linear direction when actuated so that the second side portion provides a force to the payload support portion at the third contact point in a fourth direction substantially orthogonal to the third direction.
