One of the main advantages to this type of actuation scheme is
that compliance is built into the design, which provides a more
fluid, varied movement for the camera, said Tom Secord, a former
MIT colleague of Ueda's who is now an engineer at Medtronic, a
biomedical device company in Minneapolis, Minn. He said: What
the cellular architecture shows you to do is activate small
subgrounds to scale the output. By turning individual units on
or off, which is very easy to do, you can achieve a wide range
of outputs this simplifies the control problem of achieving a
desired output for a robotic movement. The end result is that we
have a camera positioning mechanism that works in the same way
as the human eye. The devices that drive it are flexible. They
are stretchy like rubber bands in the same way the human eye
muscles are. While the mechanism is still being tested and there
are no plans for commercial development yet, Schultz envisions
several medical applications for the cellular actuation method
used in the came
