The hand works well as a model hand, however for a real time fitted prosthetic there would need to make some changes to connect it comfortably to an amputees forearm.
Solidworks
- Create Finger
- Create Palm - 2 Sides
- Work Smoothly
- Fishing wire check
- Attach Rest of fingers
- Build + Attach thumb
Electronics
- Servo -> Finger connection
- Servo -> Thumb connection
- Code to on/off switch
- Code to EMG sensor
- People can lose limbs in
- Accidents
- Military service
- At Birth
- This can hinder abilities to function in society
- Give people the functionality of a working hand
- Grab/let go
- Pick up/ grip strength
- Helps people participate in societal activities, and restores ability to use missing limb.
- The decision was to create a prototype prosthetic to act as a model for the EMG activated prosthetic hand. The name of this project, the Iron Man Hand.
- Must be able to open/close at will
- Must use solidworks and arduinos to reach our goal
- Utilize EMG Sensor as ON/OFF switch
- 3D printer
- Screws & Springs
- (3) 360 Servo Motors
- Fishing line or string
- Arduino Uno R3 Board
- Mini Breadboard
- 2 - 9V batteries
- Solder gun
- EMG sensor
- EMG sensor wires
- EMG sensor patches
- Solidworks program
- Breadboard wires
- Spray Paint
In the Test and Evaluate stage, there was multiple design changes. As seen in the pictures in the middle, the hand design and servos changed a lot to get to the final design. There was also issues with the code and servos.
- Better joint mobility
- Make design customizable
- Size changes for the customer
- Build so wrist has mobility
- Increase motor torque so hand strength is better
- Add fingerprint structure for better grip
- Rubber or Foam cushion possibility
