Week 2 Post – Haptic Glove

  1. An image or video 
    Tested the wires.

  2. A Listing of accomplishments made by all group members for the previous week
    1. Received the actuator wires and tested on them
    2. Used heat tape to prevent heat from transforming to fingers
    3. Learned about how to implement wires on gloves
    4. Connected Unity to Arduino
  3. A description of problems encountered and outstanding issues
    1. We had some conflicting test results. Still not aware if the problem lay in the wire, the gauge, or the microcontroller being used. Problems may or not be that the actuator wire is not set to form currently, the result would be a lackluster performance of the wire, possibly leading to faster degradation of the wire when activated. (Maybe we burn a wire.)
    2. There is more refined technical information on how to use the Actuator wire, considering the length, gauge, and power supply that we need to sort through and apply. Currently, we are in the trial and error stage of material and component testing:
      1. -Wires need a standardized system of shaping for memory setting
      2. -Need to figure out a “tender” was to set the memory of the wire without superheating it and burning the wire.
      3. -Controller communication in relation to power output still needs to be established and regulated.
        1. Needed current: 0.2 A; Arduino voltage: 5V
        2. Calculated needed resistance: 25 ohms
        3. Wires’ resistance: 126 ohms/ meter ⇒ 1.26 ohms/centimeter
        4. So we still need 25-1.26x ohms(set x as the length of the wire) to guarantee 0.2A current
  4. A plan for the next week of work
    1. By next week we will have determined if materials need to be re-evaluated for the practicality, or usability. Reorder any parts or new parts, create an experimental prototype that will hopefully be a functioning prototype.
    2. Keep working on Unity.
