  3. Meeting Agenda • Mission Statement • Project Description/Summary • Customer Needs and Specifications • House of Quality and Pareto Chart • SQUIGGLE Motors • Function Tree • Controls • Mechanical • Concepts selection – Pugh Charts • Failure Modes and Effects Assessment • Project Schedule • Future Plans

  4. Mission Statement • Design and build a low-cost, high-resolution nanomanipulator using the SQUIGGLE piezoelectric linear actuators from our sponsor, New Scale Technologies. • Demonstrate its capabilities in RIT’s Nano-Bio Interface Laboratory and compare its performance to commercially available nanomanipulators.

  5. Project Description • High costs ($10-50K) and inaccessibility of nanotechnology is very limiting to research • Nanomanipulators are high resolution positioning instruments, and when used with high magnification devices, has the ability to maneuver objects thousands of times smaller than what can be seen with the human eye. • We need to develop a low-cost, high resolution, three-axis Cartesian nanomanipulator • SQUIGGLE piezoelectric linear actuators • Sponsored by New Scale Technologies, a local company in Victor, NY • Our nanomanipulator will match the abilities of nanomanipulators currently on the market at a fraction of the cost. • To be used at RIT’s Nano-Bio Interface Laboratory

  6. Customer Needs Below is what the customer expects the group to try and accomplish in the design of the nanomanipulator along with its relative importance.

  7. Customer Specifications Specific requirements from the customer that address characteristics (or metrics) related to this project.

  8. SQUIGGLE Motor • A SQUIGGLE motor consists of several piezoelectric ceramic actuators attached to a threaded nut, with a mating threaded screw inside. • Piezoelectric actuators change shape when electrically excited • Applying power to the actuators creates ultrasonic vibrations, causing the nut to vibrate in an orbit - similar to a person's hips in a "Hula Hoop." SQUIGGLE info and pictures from http://www.newscaletech.com/squiggle_overview.html

  9. Squiggle Motor Photos are found in New Scale Technologies Manual – http://www.newscaletech.com/downloads_registered/02892-6-0000_SQL-RV-1p8_MotorManual.pdf

  10. Squiggle motor advantages The rotating nut turns the threaded screw, creating a smooth in-and-out linear motion. Thread friction drives the shaft, directly converting rotary motion to linear motion. This means: • No parasitic drag - less wasted power • Zero backlash (with a light pre-load) • 500 nanometer resolution • High force • Smooth velocity at microscopic speeds • Off-power hold • Standard linear motors feature direct linear drive - no gearbox • The speed and position of the threaded screw can be precisely controlled.

  11. House of Quality • The House of Quality document is a diagram used for defining the relationship between customer needs and the product’s engineering specifications (or customer specifications). • The House of Quality provides a raw score of the relationship, thus allowing the team to rank the importance of completing the given relationship. • The House of Quality allows us to create a Pareto chart.

  12. House of Quality Importance Rating: 1 = Low Importance 3 = Moderate Importance 5 = High Importance Relationships: 9 = Strong 3 = Moderate 1 = Weak 0 = No Relationship
