  1. PraximHaptic 3D Surface Emulation Erica Wodzak Davy Chiu David Mountford Ibrahim Gadala Nicholas Adams

  2. Outline • Background • Dynamic Constraint Concept • Functional Decomposition • Concepts Generation • Concept Selection

  3. Project Background

  4. Dynamic Physical Constraint Concept

  5. Functional Decomposition

  6. Functional Decomposition Device Stays In Position Under Gravitational Influence

  7. Concept Generation:High Joint Friction • Joint friction equal to arm’s free weight

  8. Concept Generation:Hydraulics • Hydraulic damper resisting arm’s weight

  9. Concept Generation:Counterweight • Counterweight at joint balances the weight of the arm

  10. Concept Generation:Motor • Motor and clutch/brake mechanism prevents arm free-fall
