Phase II: Nanomanipulator Design Problem Statement: Broaden participation and collaboration in nanoscale science by creating low cost, remotely accessible instrumentation.
Situation Update • What is a nanomanipulator? • Ultra high precision position instrument • Why do we want to make one? • Broaden participation and collaboration in nanoscale science • How will this be accomplished • Developing a commercially competitive manipulator that is low cost and controllable over the internet • What does it mean to be “Phase II” • Given entire body of Phase I Equipment to use/repurpose • More is expected in terms of progress as a result
Constraints • Manipulator must have potential to be manufacturable for less then $1000 • Team must build off phase one equipment or justify to primary customer a redesign • System must be transportable • Training must be complete before using any high cost instrumentation, including the provided microscope or any of the lab’s manipulators
Possible Solution • Using the Current Phase 1 equipment and adding functionality • For this solution the team would elect to reuse, repurpose or redesign most the phase 1 equipment provided to them. Phase 1 provided all the equipment necessary for a lead screw driven, motor controlled hydraulic manipulator. Key aspects of this solution would include • Lead screw, Hydraulic pump, 3 axis manipulator • Motor driver and Computer control scheme • Remote control scheme • Visual feed back scheme
Staffing • CE1/EE1 responsible for • Computer control of motors and sensors • Developing circuitry to control motors • Selecting sensors and integrating sensors to improve performance • Integrating microscope camera feed back • SE1/CE2 responsible for • Remote control implementation • Setting up required support back end for web implementation • Selection of web cam and other components necessary • Integrating microscope camera feed back • ME1 responsible for • Redesign efforts on current system • Lead on hydraulic design efforts • Improving backlash of system • Improving assembly/disassembly times • Ensuring that changes to system do not adversely effect performance • Machining of new components • IE1/ME2 responsible for • Manufacturability analysis and work • Responsible for machining of components • Responsible for ensuring those components are • Lead on mechanical integration of various components • Statistical performance analysis (true resolution estimations)
Project Reflection • Project requires significantly more staffing if team chooses to no use Phase I equipment and is never the less expected to meet all goals • Some specifications (backlash, resolution) might be limited significantly by budgetary constraints • Difficult project and optimal staff would relevant co-op experience • Not the case for every engineer
