Project 2 Week 2

Overall Project

  1. Why: Prosthetics improve amputees well being both physically and mentally.
  2. What exists: Current prosthetics have a learning curve,which requires the user to relearn how to move their appendages.
  3. What this project brings: This project allows the wearer to immediately use the prosthetic without having to relearn anything. The limb will move with thought processes normally used to move natural limbs.

Processor

  1. Why: The Raspberry Pi was chosen for its ability to control multiple servos. It also has a lot of information available online to troubleshoot.
  2. External Components vs internal capabilities: To control the servos, the raspberry pi requires two addition shields, but with this shields the only other thing necessary is supplying constant power to the servos.
  3. Speed/cushion/improvement possibilities: The database of categorized brain waves can be improved in the future to include other limbs, which can then be coded for.

Hardware Choices

  1. Availability: The arm was supplied by the department for the purpose of testing this project.
  2. Reliability: It has not yet been determined whether or not the arm is reliable, but the department has stated that their has been prior success controlling it.
  3. In the future, a more lifelike arm will need to be implemented, but for the purpose of initial testing we will use the arm supplied.
