Pros and Cons

  • Tedius calibration (2-3 session x (10-30 min + >1 hours))
  • For spinal cord injury application, 0.2 m/s vs average walking speed of 1.4 m/s.
  • Bad for the already weak patient. Less exercise = limited range of motion, weakbone health, and prone to pressure injuries.
  • Requires a well-trained caregiver and very prohibitive cost

Project overview

  1. CAD Design of an Exo Arm
  2. Microcontroller Programming to control an Exo Arm
  3. Exo Arm to Computer Interface

Project overview

3D Printing

  1. Easily available (UNSW Makerspace!)
  2. Allows for quick and customizable prototyping

What we will do today?

  1. Register to OnShape (online CAD)
  2. Make a cuff model
  3. [Challenge] Build the whole arm!

Groupings

  • Separate into four groups.
  • The workshop is ideally done individual or by pairs.
    • If stuck, consult your group.
    • If still stuck, consult the workshop handler (i.e., me)!
  • DO IT YOURSELF. DON'T PEAK AT THE SOLUTION.
  • Will do a demo mid way if still stuck.
