Multi-Axis Force Moment Sensor for Space (FMS)
A piezoceramic force sensor with low frequency and static capability
Purpose: provide space robotic, multi-axis, drift free force sensing capability
Basis: non-linearity under load provides frequency shift as a transduction method
Frequency shift transduction allows for wide dynamic range
Non-linearity provides for high stiffness under high load conditions
Segmentially poled ceramic and modal analysis provides multi-axis capability
Test Results show minimal influence from thermal and boundary condition effects
Application and Need:
Robotic Force accommodation control - satellite servicing
Robotic Force feedback
Space Robotic Dynamic and Deployment testing

Monthly Report for
Space Robotic FMS PreCommercialization Development
January 31, 2011
Summary
Data, based on FE modelling, of force tracking mode is being assembled in support of the FMS simulation.
Specification
First draft of hardware specification complete. Breadboard simulation specification is in development.
Design
Design modification selected, though not implemented to drawing stage.
Analysis
The plate only version of the FE model is being implemented to generate data to allow force transduction on the basis of mode tracking.
This effort is in support of the initial FMS simulation, not the design of the structure.
Breadboard Manufacturing
No manufacturing this month.
Plans for February
Continue effort to generate data for simulation breadboard specification.
