  1. 2nd Status Report April 2, 2013 Marc DeAngelis Paul Hauris Katherine Leshkow Jennifer Moore Ankle Positioning Device

  2. Project Goals • Ankle Positioning Device • Full Range of Motion • Load • Vertical Translation • Horizontal Translation • Automated Device • User-controlled • 3DOF • Hand-held controller

  3. Midterm Design

  4. Top Plate Heel Cup Criss-cross Front Ankle Brace

  5. 3D Print ¼ Scale 4.5”x 6” x 6.25” Pieces Move Design Flaws

  6. Control Algorithm Automate 3DOF • Hand-held Device • IMU • Breadboard • 45° Maximum

  7. Control Algorithm • Neutral Position 90° • Maximum 45° Servos 0° - 180° Ideal: 45°- 135° Actual: 49° (Plantar Flexion) - 131° (Dorsiflexion) Without Servo

  8. Control Algorithm Without Filter With Filter

  9. Final • After Reviewing 3D Model • Redesign Support Structure • Redesign Horizontal Translation • 3rd DOF for Algorithm
