  1. Detailed Design Review P09029 – Robotic Hand Improvement Casey Dill(ME), A.J. Connors(EE), Andrew Torkelson(ISE) Faculty Guide – Dr. Kathleen Lamkin-Kennard February 12, 2009

  2. Customer Needs

  3. Engineering Specs

  4. Risk Assessment

  5. Salford Physiotherapy Robot • 7 DOF (wrist, forearm, elbow, shoulder) • Ranges of motion are near that of human • Uses air muscles; can lift about 58 lbs. • Meant for therapy, not independent motion

  6. Saga University Arm • Provides 145° elbow flexion, 80-90° supination, and 50-80° pronation • Turns arm with “chopstick action” *Also features -5 elbow extension

  7. Wright University Wheelchair Robot • Features elbow w/ 280° of bend, and wrist w/ 360° of twist + 300° of bend • Weighs 30 lbs. and lifts 3 lbs. • 0.5 m/s movement speed • Also an iterated project

  9. Feasability Assesment Short video of the mechatronics toolkit in use http://www.ni.com/niweek/2008/keynote/simulation_with_solid_works_and_motion.htm

  10. Second Video

  11. Cosmos Motion and Labview

  12. Bill of Materials

  13. Special Considerations • Materials needed will vary depending on what’s left over from P08023 • Similar parts and materials will be used form P08023 for constancy between the iterations and because they have been tried and tested • Exact budget details are still not known
