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
