3. Overview
Team Vision
The goal for this project phase was to finalize the model design and gather anatomical information to complete the test plans for the first model. Additionally, the goal was to prepare for final model scale up and submit necessary information to ImagineRIT and design competitions.
Completed Goals:
Updated Bone Design according to SMEs input
Printed new radius for testing
Submitted to ImagineRIT
Submitted to Biomechanics Design Competition
Considered solutions to set muscle and angle string lengths
Pending Goals:
Finalize Testing
Print new model after model 1 testing is complete

5. Design Updates Updates on bones New attachment points
Larger bend in radius to allow for better wrist rotation
Hole in humerus for truss bar
Larger ‘pads’ for hinge to screw on
Printing Updates
Radius 3D printed yesterday (only bone necessary to complete testing, other bones will be reprinted after Model 1 testing is compelted)

6. Test Plans – Engineering Requirements Overview

7. Test Plans ER1,2,3 – Static Force of Muscle A, B, and C.
Test - Attach load cell to break in muscle string, hang 250g mass from hand hook, wait for arm to lower under the weight and settle, then get read out from Capstone.
Validity- Force achieved at rest must match accepted anatomical value.
ER4 – Angles at each position
Test - With each muscle attached and load cells strung, and the goniometer attached and reading out to Capstone, the arm is bent at the elbow and moved through the available range of motion.
Validity- readout must show that the arm can move from approximately 0o and 180o.
  ER5 – Max Load
Test -Hang a load of 500g from the hand hook while holding the lower arm up to the upper arm so that the angle of the elbow is approximately 0­o. release the lower arm and allow the weight and lower arm to fall.
Validity- The arm must be able to fall and stop while still holding the weight, staying upright and stable and produce steady force and angle change graphs / tables through Capstone. There should be no bending or material failure in a valid case, and the entire base must still be resting on the tabletop.

8. Test Plans ER6- Muscle Attachment Position
Test - With load cells in place, no weights, and the lower arm resting so that the angle of the elbow is approximately 90o, measure the angles of the muscles with the bones and the distance of the muscle attachment to the bones.
Validity – Both values must be within ±5%of the average adult.
ER7,8 – Deviation and Possible Positions
Test - Set the model in each possible position with the 250g weight. For each position (supinated wrist, pronated wrist, flexed elbow), allow the device to sit, with no contact or extra support from an outside object for 1 minute, measure deviation.
Validity – The position set by the user must not deviate by more than ±1cm during the wait period.
ER9- Time Required for Assembly
Validity – The full assembly takes approximately 20 minutes or less to assemble and can support a 250g weight from the hand hook upon completion.
ER11- Structure Dimensions
Validity – The base of the device must be within 2ft by 2 ft.
