Progress Report II Prototype I Assignment

Second Progress Reports for Prototype I go here.

Green Wu- Progress Report II for Prototype I: Bicycle-powered generator

Goals for the week:

- Meet with the CPRF client to get measurements of her wheelchair
- Get the LCD screen to display simple text output
- Find an alternator/generator that will be providing the power for the modules
- Acquire a bicycle and start designing the  stand

Meeting times/dates

We had a meeting in the lab at 2 pm on Friday

Individual Hours:

Alex: Done more research on using Arduino to power the LCD screen. Found another online example that is supposed to display output to the screen. Haven’t been able to work on it yet though. Here is the link: http://www.ladyada.net/products/tfttouchbreakout/
I Downloaded PureData and now I am trying to find out if it will be able to provide output we are wanting

What we did:

Tom gave us a DC motor with gearing. We went to the lab and experimented with small 5V motor to try to simulate how we will be able to use the generator.
On Arduino front, we’ve been continuing to learn the basic programming and trying to get the LCD screen to work. We also connected the  5V motor to the Arduino to experiment with the power supply pins
We posted  a request for bicycle on freecycle.org but we haven’t had any replies yet

What we didn’t do:

Did not get an actual bicycle to start working on
We weren’t able to talk to the end customer to hear their input and get the wheelchair measurements

Where we are stuck:

We are stuck trying to get the LCD screen to work. We need help compiling the code and uploading it to Arduino.

Notes/Misc:

[Team Glen] – Progress Report II for Prototype I: [Smart Mailbox]

Goals for week 2:

  • Get Xbee Pro shields DIY kits assembled this week.  The shields are our main goal so we can start working with Xbee Pro wireless communication and programming the Xbee Pro with Arduino.
  • We now have the actual inside dimensions of the apartment mailboxes (Thanks to Beth Sneed at CPRF last week) so we can start making an insert for mailbox with mounted IR sensors.
  • Modify the code we designed that works for one IR sensor and have it work for two IR sensors.

Meeting times/dates

Our regular meeting hours are:  Friday 12:30 PM to 3:00 PM

We met last friday at CPRF to check mailboxes and take measurements for a couple of hours.

Individual Hours:

Dhreen:  Worked on the x bee soldering two hours for 3 days. I had to first understand how to do it and now I know how to do it very well.

Glen:  I spent about 10.5 hours working on the wooden insert for the mailbox prototype design.  Cut wooden insert to dimensions, finding parts to work with our new IR sensor design, soldiering microscopic parts using specialize soldering equipment and working on proper sensor alignments.

What we did:

  • We successfully completed the x bee soldering. Now we will test them to check the range they can cover.
  • We all meet up with Beth Sneed (along with a small gathering that started forming around the mailbox room) last Friday to get the actual inside dimensions of the mailboxes used at CPRF.  We also learned how the apartment style mailboxes work with the postmaster master key as shown here:  http://item.mobileweb.ebay.com/viewitem?itemId=270637425011&index=4&nav=SEARCH&nid=00878384507.  The operation of the mailbox forced a design change to the IR sensor insert we had planned.  The top to bottom sensor will not work for the inserts because postmaster would not be able to put any mail inside mailbox.  Also we have a good idea how far the Xbee Pros (which we now have) will need to transmit for the project to be successful.  We also have noticed that for Beth Sneed (and probably with other motor coordination deficit CPRF residents) that opening the box with a key is very cumbersome.  The opening of the mailbox itself is probably more important than a mass notification system for these residents.
  • Side Note:  Maybe looking into designing one RFID automatic opening and closing mailbox with mass notification system custom made apartment style mailbox for final project.  Not for sure. 

What we didn’t do:

The mailbox insert is almost done for our first prototype design.  Still got some work to do on it before it is complete.  Getting the super microscopic IR sensors (2.7mm) soldiered, properly aligned and working is not easy.  The mailbox insert plans changed after seeing how the mailboxes open with postmasters master key.  The first mailbox insert plans with top to bottom IR sensors would not have worked at all.  A lot of planning and research went into finding the best insert design that will actually work with any type of mail inside the mailbox.

Where we are stuck:

Our project is going fine and we are not stuck.

Notes/Misc:

Need to start experimental programming with Xbee Pro next week to see how far Xbee Pros can communicate.  Plan to write a blinking light (back and forth) communication program to see the distance Xbee pros can be separated before communication stops.  We will know when communication stop by observing the LED light that will no longer blink, marking our max distance we can separate the two Xbee Pros.

Electric Chair – Progress Report II for Prototype I: Electric Chair

Goals for the week:

  • Meet with residents at CPRF to inspect chairs and discuss project.
  • Determine the new chair model for the customer.
  • Practice code on Arduino
  • Determine “new” project direction based on customers current control interface configuration.

Meeting times/dates

  • Meeting at Thursday from 7-9 pm is cancelled because 2 group members can’t come.
  • Friday from 2 – 4 pm

Individual Hours:

Time spent individually is determined by the individual. Just do your best to make progress on your task for the week.

What we did:

We met with CPRF residents and discussed what they really wanted to improve their wheelchair. We also takes some notes regarding specs and CPRF residents showing us the capabilities of their wheelchair. We also have successfully obtained wheelchair specs in PDF format from Greg of CPRF regarding what kind of new wheelchair the resident is going to acquire.

What we didn’t do:

We did not order any parts, or for that matter create anything gear directly towards the prototype.

Where we are stuck:

Our project took an unexpected turn this week, which resulted in the need to come up with a new concept.  Upon meet the residents at CPRF, we were told that 3 of the residents want the lighting system.  We also discovered that their chairs already have battery level read-outs, so that idea was no good.  We finally got the new chair information an d realized that the controls on two of the residents chairs are the same and more impotantly the interface accepts apps, and are also supposed the be compatible with the arduino.  So, we are back on track with a new idea of using the chair controls to control the lighting system.

[safe] – Progress Report II for Prototype I: [Medicine notification system]

Goals for the week:

Our group is planning to do many things this week.

1. Buying a scanned reader PS2 type.
2. Building an arduino circuit and trying to play with it.
3. Practicing C programming and some codes.

 

Meeting times/dates

Friday        2/24      2 pm for an hour

Monday    2/27     9:30 pm for an hour chatting via Skype.

Thursday  2/30   2 pm for an hour 

Individual Hours

All four of us met on Monday via skype for about 30 min. 

We also met at the lab on Thursday for about an hour.

These are some of the individual efforts:

Ghassan  and Ryan spent 2-3 hours this week building the arduino circuit. 

Ahmed spent about an hour  on buying scanned reader PS2 and waiting to receive it. 

Julio spent about an hour doing some team leader stuff and thinking about what the next step in the project would be ans he also draw our project’s diagram.

Ryan spent about an hour and a half typing up notes of the last meeting with Dr Joh.

 

What we did:

We’ve decided to use  three  different lights for the outputs. They are  Refills, expiration, and a notification to take the medicine. we will record our own bar codes.  A member of the group has bought a scanned reader SP2  and waiting for it and others are working research and build on programming of an Arduino board.

What we didn’t do:

how we  connect the scanner to the arduino?

Where we are stuck:

1. using C programming and some codes.

2. how we will connect the scanner to the arduino .

Notes/Misc:

Research a way to power the arduino. we might use 9 volt battery or using Ac to Dc converter.

Team X – Progress Report II for Prototype I: Wheel Chair Curb Detector

Goals for the week:

We plan on having code that will detect a curb. Taking an average distance and comparing it to the real time distance. Trigger the wheel chair to stop when a difference of 6 inches is detected. Have a way to clap the sensors the poles on the RC car and be able to adjust the angle. Research a way to power the arduino from the RC car battery. Research IR sensor that have more range.

 

Meeting times/dates

Sunday at 4 pm and Thursday at 1 pm

Individual Hours:

Nhat Nguyen – spent 1.5 hours looking for IR sensor mount at stores.

Bana Mahamane : spent 1.5 brainstorming on code.

Samuel Ky: spent 1 hour write code.

 

What we did:

Wrote working code using one IR distance sensor to detect a big change in average distance.  The code works by calculating an average distance and comparing it to the real time distance. If real time distance was greater than the average distance plus 20 centimeters, which is about a 7 in change in distance it will light up the LED.

What we didn’t do:

Sensor mount couldn’t be accomplished, I will have to make it because it I couldn’t find it in store.

Where we are stuck:

Wheel chair from CPRF.

Notes/Misc:

We met with CP residents and got value input. They really wanted a device that detected a curb.  One of the resident stated that he fell off a curb and broke his hip. They stated that if the system would automatically stop the wheel chair briefly with an audible signal. A way to turn off or bypass the system. Some of the wheel chair can go up to 8 mph, so a way to slowly stop the wheel chair would be a nice feature. Some wheel chairs are equipped with seat belts. A side sensor to detect a curb for turning was suggested. Also a sensor for backing up was suggested.

MAR – Progress Report II for Prototype I: Wireless GPS Tracker.

Goals for the week:

* We are planning to put our initial steps to building the switch for the bluetooth device to turn it on and off. We are trying to figure out what kind of voltage source we need and how to design the circuit to turn it on and off when needed.

* We are planning to look for a suitable switch for our device.

* We have found out some links to get familiar with android application building. We are planning to study it more and start drawing the flow chart for our first application.  We are trying to figure out the exact dataflow from catching the bluetooth signal to send a message.

               Links we foundout for our project :

                                       - http://developer.android.com/guide/topics/wireless/bluetooth.html

                                      -  http://developer.android.com/guide/topics/location/obtaining-user-location.html

                                      – http://developer.android.com/reference/android/telephony/SmsManager.html

                                      – http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html

* We are planning to start building our first program piece in JAVA to identify a particular bluetooth signal.

* We are planning to meet the consumerat CPRF who is interested about our GPS tracker sometime during this week. We hope we can get more information about our product from the client’s side.

 

Meeting times/dates

Our regular meeting times are Sunday 4 p.m to 7 p.m and Friday 4 p.m to 7 p.m. Besides, team members will work on meeting the CPRF consumer who is interested about our product.

Individual Hours:

Team members will spend their time as needed to work on doing researches, learning and building their piece of the project.

What we did:

As a team we are working on building the programming code for the project. We started with building a java code to catch a bluetooth signal. We have found some code structure to do the task and working on assempbling them together.

Abdullah Alrowaili: I found that the SMD need only 3.3V  and it  uses only 26uA in sleep mode while still being discoverable and connectable. and I got the battery for it. and I am going to test this week and aslo I found that it we can connect it to an android phone easly. Also I have alot of information about how start it in this website. Also I am going the CPRF member who intersted on our project Friday March second.

S.R.P.R – Progress Report II for Prototype I: Dual Mode Table

Goals for the week:

  • Initial Design for the tray and mount by Wednesday in CATIA.
  • Pick up Tray and buttons from Greg (CPRF).
  • Experiment programming on Arduino for Button (Input).
  • Choosing what design we want to build and find out what/how many components required.

Meeting times/dates

Saturday at 3 pm -5 pm

Wednesday at 9 am – 11:30am

Individual Hours:

Each member of the group are planning to spend a minimum of 3-4 hours.

What we did:

  • Initial Design for Table is done in CATIA
  • Picked up Tray, push buttons, arm rest for mounting the table.
  • Tried running examples in Arduino and got familiar with input/output using push buttons and LED.
  • Decided on what are the components we required and did research on some potential components.

What we didn’t do:

  • Collecting components either from Online or from Senior Design Lab.

Where we are stuck:

  • .We thought of using different material for Table instead of what is being used. We are thinking of using electromagnetic locks for our design so we are thinking of kind of metal that can be light and durable which can be use for the table. We haven’t come up with the material we want to use yet. We need to show our design tomorrow and go from there.
