| The problem
of sensing undesired motion during micromanipulations is one of small
signal-to-noise ratio. The technical and design requirements of the
Micron sensing system are: ·
Resolution: £
10 mm ·
Small and

Non-obtrusive
to the surgeon Micron 1 SensingThe first prototype of
Micron sensing system consists of a 6-DOF inertial measurement unit (IMU):
·
Three rate
gyroscopes – Tokin CD-16D ·
Tri-axial
accelerometer – Crossbow CXL02LF3 The sensor suite is
located at the back end of the handle in Half-Micron 1 and Micron 1.
