Final Project Proposal
Project Ideation
1- Tell us about the purpose of your project. Which problem does it solve? Why do you care about this? What were you inspired by? Include images and videos of similar projects
The purpose of the project is to create a robotic arm. It will be my first step to design a prosthetic arm and understand the challenges that I will face, and it will be a fun project.
I was inspired by the movement of 3D printed prosthetics world wide. They are accessible and cheaper alternative to what we currently have.
2- Describe the project idea and general features. How would it work?
The Idea is to make fingers with segmented parts connected with wires that are connected with servo motor. the servo motor will pull the wires moving the fingers into a grasping motion. when the servo releases the fingers will return to the first position by recoil.
2 fingers each will be connected to a servo except the thumb which will have a servo alone. and wrist rotation will have a single servo motor.
3- Sketch your project: You may use pen and paper or a simple sketching tool like Microsoft Paint or Photoshop
The Main parts will be 5 fingers, Palm and base.
The Fingers will be 3 parts except the thumb will be 2 parts.
The palm will have the base for the fingers and mounting for the servo motors.
The Base will Contain the electrical components.
Project Planning
4- Describe the Technical Modules that your project consists of
Construction Parts
Laser Cut parts.
Make the Fingers like human joints.
Input
(Sensing, Tactile Input, and/or Graphical Input)
Graphic input
Will use mobile app to to send Input to the servo motor to either move the finger to flexion or releae the finger.
Action
(Physical and/or Graphic)
Physical
Servo motors will move the fingers into grasping motion
Brain
Arduino
Power Management
Adapter 6V
5- Create a cardboard prototype of your project, demonstrating the project face as well as internal movements and mechanisms. Include a demo video and photos of the prototype.
6- Categorize your project’s User Features into: Minimum, Complete, and Nice-to-have features. List the required action and input components per feature.
Minimum Features: are the least amount of features that would demonstrate the coverage of all the technical modules and their complete integration
Complete Features: are the set of features that will complete your original project objective and vision
Nice-to-have Features: are the extra set of features that will make the project cooler, yet they need extra time, effort, and/or resources to finish
Minimum User Features
Example: Hand grasp objects
Action: Finger moves to close. Servo motor moves the finger to flexion.
Sensing: no sensor
User Input: Mobile input to the Bluetooth module to increase servo angle.
Example: Hand release objects
Action: Fingers moves to open. Servo motor release the finger so that it extends.
Sensing: no sensor
User Input: Mobile input to decrease servo angle.
Complete User Features
Example: Single finger control:
Action: Finger moves to close. Servo motor moves the finger to flexion.
Sensing: no sensor
User Input: Mobile input to the Bluetooth module to increase servo angle.
Nice-to-have User Features
Example:
Action: Wrist Rotation. Servo motor moves the palm left and right
Sensing: no sensor
User Input: Mobile input to Servo motor to increase the angle.
