Project 3.1.7 Machine Control Design

Team Members: Isabel, Daniel, Carley

Problem 1: Start / Finish Line (Hardware Level 1 | Software Level 4)
The Olympic committee would like your team to invent a control system for use with track and field running events. They want this device to automatically record the time and beep when the first runner crosses the start / finish line.

 Final Program



CONCLUSION QUESTIONS

1. What was the most difficult part of the problem?

The most difficult part of the problem was wiring the switches to coincide perfectly and properly with the program already set in place - the mix up and the innumerable pieces of wire were really hard to operate around as well, and figuring out and keeping track of the inputs and outputs made things even more difficult.

2. List and describe two features that were not part of the design problem that could be added to improve your design.

Better sensors would have been nice - perhaps color sensors pre-programmed to sense the colors of the contestants in the Olympics to differentiate and provide proper statistics for the record. When we went to record the time on the program, it would have also been more convenient to have it continue going, but stop as each person crossed the line. However, given the time limit, such a feat could not be achieved.

The Smartest Machine on Earth

What is "machine learning"?
Learning from examples.

How did the IBM team employ that concept in the development of Watson's AI? What advantage did that provide over previous attempts at "intelligence"?
By having the machine learn from examples it can create patterns that will help it figure out things out for themselvs. This facilitates the IBM teams job because somethings are to difficult to explain like "what is the letter A" it's easier to show it many examples of a letter "a".

I've often mentioned the term "Empirical Scepticism". What does that mean? How does that relate to the concept of Machine Learning? How does this relate to your life?
Empirical Scepticism is questioning beliefs on the basis of scientific understanding. You learn off of trial and error and it seems that machine learning is learning from examples and everytime watson has a mistake he corrects it and tests it.

Ground Zero

Happy New Year!

Ground Zero:

What different "trades" (types of construction work) are featured in this video? Name at least three.
Steal work, glass work, bronze memorial plate work.

What aspect of the project is most interesting to you? Why is that?
The aspect that was most interesting to me was how they had to have all the materials tested to make sure that it could support the building. For example, testing creating the cement and testing it on site, and making the glass and testing it.

Happy Halloween!




I tried my best to use the inventor program, though everytime I tried to do something it seemed something else would go wrong. I even tried adding color but when I saved it, the color didn't save or something happened.

The Deep Dive

1. “From the buildings in which we live and work, to the cars we drive, or the knives and forks with which we eat, everything we use was designed to create some sort of marriage between ______form___________ and ______function___________.”


2. The folks at IDEO state that they are not experts in any given area. But, they do claim to be experts on the _Process of Design______, which they apply to the innovation of consumer products.


3. After the team of designers is brought together, told the problem, and informed they have five days to “pull it off,” what phase of the design process do they immediately engage in?

They first listed all the issues and safety hazards and then got out to observe shoppers.

4. Give two examples of what the team members did during this phase.
a. Went to the supermarket to see the product in use

b. took pictures to later analyse what was going on


5. List five rules-of-thumb that IDEO employees follow when they share ideas during the brainstorming phase:

a. One conversation at a time.
b. Stay focused on topic.
c. Encourage wild ideas.

d. Differ Judgement

e. Build on the ideas of others.

6. Why should wild (and sometimes crazy) ideas be entertained during the brainstorming phase?
Because others can than build of those ideas.


7. After the brainstorming phase was over, the team narrowed down the hundreds of ideas by ___Voting____ for those ideas that were not only “cool” but also _____Build-able____ in a short period of time. What phase of the design process is this called?

Enlightened trial and error

8. IDEO believes that the ideas and efforts of a ____Team____ will always be more successful than the planning of a lone genius.



9. Once the ideas were narrowed down and divided into categories, the group was split into four smaller teams. What phase(s) of the design process was each of these groups responsible for?

1. Shopping
2. Safety
3. Check out
4. Finding what you're looking for.

10. The leaders at IDEO believe that _____Crazy_____ behavior and a ____Playful____ environment are two important reasons why their employees are able to think quickly and creatively to produce innovative results.



11. Sometimes, people come up with great solutions that work by trying their ideas first, and asking for _____Forgiveness_____ later.



12. Design is often a process of going too far and having to take a few steps back. What phase of the design process would the critique of the four mock-ups come under?

Iterative Design

13. Upon critique of the four teams’ models, it was obvious that none of the teams had developed an optimum solution. However, the people at IDEO believe that it is important to ___Fail___ often in order to ____Succeed___ sooner.


14. What percentage of the entire week’s time did it take to fabricate the final prototype?

I'm not totally clear on the percent but they did spend the whole last night building it.

15. Instead of showering his design team with a tremendous amount of praise, what did the boss require his employees to do with their new design?

Test it out and outside people's opinions.

16. Of all the things that we are surrounded by every day, what has not been placed through the design process?

Nature.




Conclusion

1. What did you find to be the most impressive part of the team’s effort?

 I think was most impressive was the perseverance the team had to accomplish the task. They didn't give up.

2. What advantages are there to having a design team with members that have non-engineering backgrounds?

It gives room to more wild ideas that they can build off of when designing new things.

3. There was a point in the process where a self-appointed group of adults stepped up, stopped the ideas, and redirected the group to break up into teams. Why was this done?

The breaking up into groups was necessary because it helped redirect the group and have a better focus on different aspects of building the car, or else that phase of the design process could have gone on forever.


4. At the end of the video, Dave Kelly states, “Look around. The only things that are not designed are the things we find in nature.” Can you think of anything that would contradict this statement?

Parks and gardens would be a contradiction because landscape architects design an area by using plants, etc to make an area look more appealing.
