The objective of this project was to make a portable, easy to use device, that can help in the treatment of people who who have peripheral neuropathy in the feet. Many people do not have the time to go to a masseur every time they feel they need a massage to relieve pain in their feet. My device would solve this problem by making a portable, mechanical foot massage machine. Not only can it be taken anywhere, but it can be used on demand. It can also be used for however long the user would like to use it, making it a cheaper alternative to costly massage parlors.

Step 1: Parts List
360 degrees rotating servos
Step 2: Frame Assembly (Base)
-Cut 2 polypropylene plastic board in the shape of a semicircle.
-Drill 8 holes on each side of the rectangular board. These holes are for the L-Brackets that attach to the top and sides of the first level and second level of the prototype for support see pics. The second level supports the attachment of servos to the prototype. (see the step on Servo attachment.)
-Drill another 8 holes on the top plate for the L-Brackets to attach to the semicircle.
-Cut three circles on the board with a diameter larger than the size of a servo. 2.5 ". Keep the three circle cutouts. You will need to create the treatment pads.
-Measurements: Top plate 3' x 12" 1/4" thick Servo support plate 3" x 12" 1/4 thick
Step 3: Frame Assembly (Top Plate Hole Configuration)
You will need to drill 3 holes 2.5 " in diameter. These will serve as the opening for the treatment pads that attach to the servo wheel which attach to the servos. The separation between servos will be 1/4".
Step 4: Servo Attachment
You will need a rectangle channel bar 1" square.12" long. You will attach to the middle of the second plate.
The second plate dimensions are 3"x 12" 1/4 thick. These plates are made out of cutting boards from wal-mart.
Make sure that the Rectangle channel bar is in the very middle you will need to align the servos with the treatment pad opening on the top plate.
Step 5: Electronics/Software Code
We used and UNO Arduino Micro controller, attached the 3 servo to the controller to the PWM pins. We then attached a blue-tooth module to pins 0 and 1 TX and RX. An on/off switched was attached to the blue tooth module in order to turn it off when uploading code, since the controller would freeze when any new code was uploaded. A blue-tooth apps was down loaded for the cell phone to controller the BT module and the innovation.
Step 6: Treatment Pad Cover
Cut a foam pad 3"x 12" this will serve as the cover for the treatment pads. You will them measure out were the treatment pads touch the foam pad and cut out three holes 2.5" see attach pics. You will need several strips of Velcro to secure the foam pad to the top plate of the prototype see attached pics.
Step 7: Treatment Pads Assembly
To create the base of the treatment pads you will need to use the circular cutouts from step 2.
You will need to purchase a massage glove on E-bay,Wal-mart or Marshalls take apart see pics above. Take off the ball bearing assembly and epoxy to the 2.5" circle cutout from step 2. This will create the treatment pad see attach pics.
