Overview First Semester Second Semester Research of Skin material Order material Preliminary testing Research FSR Design an Array of FSRs Evaluate the skin material with pressure sensibility using FSR sensors Record data Overview

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. Purpose

Materials Silicone rubber (Dragon Skin 10 MED). FSR A201 Vacuum Chamber Kit w/Pump Homogenizer Resistors-100K Ohm Arduino Uno LEDs Acetone Materials

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

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. FSR Sensor A201
