Overview

4. This growing study can be applied to robotic arms, which can gather information and respond to given external inputs.
The purpose of this project is to receive tactile sensory feedback from the artificial skin-like surface. The feedback will improve control.

6. The equation above is the output from a FSR device.
FSR Theory

7. FSR Sensor A201 Model 201 FSR will be used.
It is a piezo resistive force sensor.
The harder the pressure, the lower the resistance.
The dynamic range of this sensor can be modified by changing the drive voltage and adjusting the resistance of the feedback resistor.

10. The design of the project will be a skin platform that consists of an embedded grid of FSRs that are spatially arranged.
The platinum silicone will then be poured on top of the grid.
