P10029: Control Enhancements for Air Muscle Biomimetic Hand Customer: Dr. Lamkin-Kennard Faculty Guide: Ed Hanzlik Team Members: Zach Wessner, Jaci Tylkowski, Alex Bean, Mark Wood, Tuan Tran, Kevin Mudrak October 16, 2009

 P10029 is a continuation project ◦ Physical system was built by P09023 ◦ Final design will be integrated into Dr. Lamkin- Kennard’s pneumatically driven scalable robotic hand devices  Controls system is the focus ◦ Maintenance and repair only of the physical system  Virtual and Physical prototypes ◦ Virtual system modeled in SolidWorks and both controlled by LabView

 System Level Design Review – 10/16/09  Detailed Design Review – 11/06/09 (3weeks ) ◦ Virtual Concept Selected ◦ Physical Prototype benchmarked ◦ Controls (Physical & Virtual) designed  Project Management Review – 11/20/09 (5weeks) ◦ Controllable virtual system ◦ Controllable physical system ◦ Calibration Plan / DAT Plan

 Build kinematic model using SolidWorks/Cosmos Motion Builder  3-D Closed loop feedback for both hand and model.  Drive kinematic model using the inputs from the mechanical hand.  Virtual and Physical Models output displacements  Quantitative analysis comparing displacements of mechanical hand to model.

 Top 3 Metrics based on the HOQ ◦ Functionality ◦ Accuracy ◦ Repeatability

 Goal: 1.LabView 2009 SoftMotion: meets objectives? 2.Educate team for full-scale model 3.System architecture  Plan  Simplified SolidWorks model  Research & tutorials for LabView  Develop LabView control (single axis) o Functional Evaluation  Joint design, movement, controls scheme, feedback  Iterative (adding complexity)

SolidWorks Model 1 DOF Simulated Joint

 Issues / Risks: Scan Engine Period [5ms or 10 ms] / Deployment Virtual Controls Scheme differs from Physical Virtual Error = 0?

 What are we doing?  Kevin/Tuan  WIP  Document the bitching about the physical system  USB 2.0
