6. Conclusion

6.1 Results and Expectations

Our final design met our goals and expectations for the most part. The device has all the functionality we set out to put in it. It is not as reliable as we had hoped it would be, and would need more testing before it is used in laboratory setting. If we had more time to work on it, we would add the ability to move the motor fractions of millimeters, as opposed to a whole number of millimeters.

6.2 Design Standards

Our device conforms to the RS-485 communications standard. We ensured this by following application notes for RS-485 equipment and testing our design with a commercial RS-485 transmitter.

6.3 Intellectual Property Considerations

For this design we modified Bruce Land's UART code, which he gave permission for use in projects in this class. All other code was written from scratch. We did not perform any reverse engineering, as we had application notes and datasheets for all the protocols we needed.

6.4 IEEE Code of Ethics

Our design practices follow the IEEE Code of Ethics. For example:

  • There are no conflicts of interest in our project. We have been open with all parties internal and external to the project, thus avoiding any possible conflict of interest.
  • We have been honest with our claims and documentation. We have researched the applicable technologies thoroughly so we feel these claims are realistic.
  • We have neither accepted or offered any bribes before or after the projects completion.
  • In making our project we have treated all people we worked with fairly regardless of race, age, gender, nationality or any other personal differences.
  • We have not injured any people in any way, including through their property, reputation or employment.

6.5 Legal Considerations

There are no legal standards applicable to our design.
