My Final Project example

My final project idea consists of creating an assistive device for people with Brachial Plexus Paralysis, controlled by voice or a button. The purpose of this device is to help people with arm paralysis rehabilitate the muscles in their hand, using the device to restore mobility and strength in the affected arm. At the moment, my sketch includes some initial ideas, but I am confident it will take shape and evolve throughout the FAB ACADEMY, ultimately resulting in a functional prototype.

Functionality and Mechanism

The device will function as a robotic glove or exoskeleton worn on the affected hand, designed to assist in movement and rehabilitation. It will use motorized actuators to mimic natural finger motion.

Hand Anatomy and Movement

The following images show the bones and movements of the hand:

Control Methods:

  • Voice commands: The user can control the device using simple commands like "open" and "close"
  • Button interface: A push-button will be available for users who prefer manual operation.

Key Features:

  • Grip Assistance
  • Rehabilitation Exercises
  • Wearable & Lightweight

Possible Materials & Components

Component Purpose Possible Options
Frame Support structure of the glove/device 3D-printed PLA, carbon fiber, flexible TPU
Actuators Provides movement for fingers Servo motors (SG90, MG995)
Sensors Detects user intent & movement Force sensors (FSR), flex sensors

Benchmark: Existing Solutions & Inspiration

Next Steps

  • Refine the design using 3D modeling
  • Prototype different control mechanisms
  • Test different actuators and materials
