2015-03-29 (Su) Self Contained Haptic Distance Sensor

A list of changes to the enclosure was made which corrected the known problems with the design. The 3D modeling and rapid prototyping saved considerable time and resources by comparing sizes in reality as opposed to virtually or mathematically. Real life sizes of parts were measured with digital calipers and translated to the model. While modeling, screen captures were taken so an animation could be generated which showed the changes in a brief format.

Changes:
  1. Shrink wall thickness from 3mm to 2mm
  2. Change post shapes from pyramids to cubes
  3. Revise lid
  4. Hold servo externally
    1. Add posts
    2. Use screws to attach
  5. Shrink and move logo
  6. Shrink interior size
  7. Remove diagonal screws from ultrasonic distance sensor footprint
  8. Add post to suspend ultrasonic distance sensor
 
Animation of modeling changes

To do:
  • Design method of holding the enclosure together neatly
  • Design mount for servo which uses screws instead of bolts
  • Design way for servo cam to push on user without rubbing
  • Model new enclosure and lid
  • Model enclosure 
  • Print enclosure
  • Test for usability
  • Refine design
  • Program Arduino
  • Test device
  • Write instructions
  • Propose project for TCP for workshop
  • Make files public

The rest of the posts for this project have been arranged by date.
