Goals for Week 8

Final Layout of Beta

1. Are we going to use an X layout or a + layout for brakes? (Completed)
2. How will we attach brakes so they do not slide when brakes are active? (Completed)
3. What type of battery will we use? (Completed)
4. Complete initial Beta build. (In Progress)
5. Complete Bet CAD model. (Finishing)

Alpha Testing

1. General Testing (Completed)
2. How will the brakes perform in different orientations (compare to normal orientations)? (Completed)
3. Engineering Requirements Testing. (In Progress)

Logistical

1. Where are we going to purchase products supplied by Amazon? (Completed)

Electrical Safety

In order to examine the safety of the device when being worn by the patient, an assessment was written with a focus on 3 different parameters; Thermal Exposure, Chemical Stability, and Electrical Exposure. The following document details the topics covered and gives an argument for the devices safety in these areas.

here.

To evaluate the thermal safety of the device the system was monitored to determine the thermal emitters in the system. It was determined that the Magnet was the only thermal emitter.

A test was then performed to examine the devices temperature over time in a worst case scenario. The image below shows the Alpha system with a temperature sensor attached to the magnet. To simulate worst case scenario, the magnets were powered at full power (12v) and ran intermittently ith an on time of 1.5s and period of 3s. The test was performed for an hour. The results of this test are demonstrated in the paper on Electrical safety shown above.

Build And Test

Link to Test Results here Changes made:

• Revised locking system to make it less cumbersome.
• Added a guard for the magnet to protect user from any heat that might be created.
• Rounded base to make comfortable for wearer.
• Added slots to guide Velcro and fasted chassis more reliably.
• Added counter sunk holes to protect user from pressure from screws.

Test Plan Timeline:

Alpha

• S3, S17, S21 - Have not been run yet, can be run.
• S9 - S11, S26 - Need human subjects. May use project members to simulate tremors for this testing.

Beta

• Testing to start Week 10 (Dependent on Beta Construction)

Plans for next phase

Individual Plans

Ramy

• Crimp and set swivels for beta
• Prepare plates and attach to beta
• Attach resizable wearable pivot to beta
• Document all manufacturing plans for force distributers
• Test plates efficiency and wearable pivot efficiency for improvement opportunity.

Sarah

• Add any updates as to the Solidworks model as they arise.
• Attach all of the parts that need to be sewn on. This includes finishing the ribbing if needed, attach the 4 new brakes, MOSFET’s, Arduino and clean up wires.
• Assist in writing the paper for my portions that I specialized on.
• Provide documentation including model images for the poster.

Jamey

• Further develop and refine the brake chassis for optimum effectiveness.
• Print all brakes and tests the integration of the full system
• Work with Ramy to test the effectiveness of the hand plates, wrist guide and brake assembly integrated with brake assembly and electronics.
• Find any points that can be improved and revise the design.

Nick

• Begin wiring Beta
• Start control code for Beta if possible
• Document wiring and repair/build info
• Test 4 magnet system

Pete

• Work on individual paper sub-section
• Take lead on Poster Creation, close contact with team for feedback
• Follow up on Access Tech Conference and fill out any submission documents
• Finish Alpha testing
• Create testing schedule for Beta testing
• Send follow up IRB email and send additional information if need be

Key Milestones for Next Phase

Beta

1. Complete initial Beta build.
2. Complete Beta CAD model.
3. Start Beta testing (Start with non control algorithm dependent tests, continue to control algorithm tests if enough progress is made)
4. Adjust control algorithm to function with 4 Electromagnets and 2 9DOFS (and either temp sensors or stretch sensors)

Alpha Testing

1. How will the brakes perform in different orientations? (compare to normal orientations)
2. Finish Engineering Requirements Testing.
3. Do Stretch Sensors add enough feedback to justify not using temperature sensors?

Logistical

1. Create a live 3-D printing schedule to ensure constant printing.
2. Establish another meeting time that entire team is present.

Imagine

1. Where can we get a mannequin hand for display?
2. What type of fixtures do we need to demonstrate key subsystems of device?

Paper Work

1. Break paper down into sub-sub sections and assign each team member a sub-section.
2. Create soft deadlines for completion of sub-sections.
3. Create poster for Imagine (look at old posters for ideas / layout)
