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
- CAD Design of an Exo Arm
- Microcontroller Programming to control an Exo Arm
- Exo Arm to Computer Interface
3D Printing
- Easily available (UNSW Makerspace!)
- Allows for quick and customizable prototyping

What we will do today?
- Register to OnShape (online CAD)
- Make a cuff model
- [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.
