Blue Team – Progress Report III for Prototype II: Smart Cushion

Goals for the week:

Try to get our cushion up and running with the pumps and come up with how we are going to display it at EOH.

Meeting times/dates

Saturday 12pm at the workshop in Wallace.

Individual Hours:

Travis: ~2 hours getting information together to make the board for EOH.

Jared: ~2 hours getting the code fixed so that it can utilize 4 pumps and turn them on or off.

Brian: ~2 hours getting everything put together on the cushion so that all we have to do next week is get our remaining parts in and get them attached.

What we did:

This week we did more individual work.  At our meeting we talked about what needed to be done and gave everybody individual tasks to complete for the week.

What we didn’t do:

The board is not complete yet, I have simply gathered information for it to put onto the board.

Where we are stuck:

At the moment everything seems to be going well and as long as our solenoid valves come in on time then we aren’t in any state of emergency.

Notes/Misc:

Team 4 – Progress Report II for Prototype II: Easy Opener/Closer

Goals for the week:

Start building the upper part of the device.

Meeting times/dates

Tuesday : 7pm to 9 pm

Thursday : 3 30pm tp 5 30pm

Individual Hours:

Zubair : Working on building the box for the Arduinos and wires.

Nick and Michael : Working on Arduinos and designed the top part.

What we did:

I think we are pretty much sure that we will complete our project for Senior Design 1 by next week. This week Zubair was still working on the base. With the help of Tom, we figured out that an opaque box will be useful to be placed on the base of the device so e can utilize the space for the switch as well as get rid of wires by putting it into the plastic block. We ran out of plexiglass as well as switch otherwise we would have completed that last week but Michael has bought all the stuff.  He also bought the rods for the frames. Also Michael and Nick were working on designing the top part and we have our design so tomorrow we will be working on building the top part and getting everything in order and we are hopeful that we might be done by next week so we can save the project for the last minute finishing in the last week. Also I will be posting pictures next week.

What we didn’t do:

We could not built the plastic box and finally be done with the base part because of the plexiglass was unavailable on Thursday and we spent most of our time testing it on the form. Also large sized rods for frames were not available so we have to wait for a week until we buy it and start working on it. 

Where we are stuck:

As of right now, I don’t think of anything we are stuck on. Tom is always there to help us if we stuck somewhere :)

3! – Progress Report II for Prototype II: Mechanical camera control system for wheelchairs

Goals for the week:

  • To work on the top part of our design
  • Cut plexiglass for the box
  • Work on gears

Meeting times/dates

Tuesdays and Wednesdays, Wallace hall @ 6 pm

Individual Hours:

Work as a team

What we did:

We drew our top base and the tabbed box in inkscape and cut styrofoam to see if all the dimensions are fine or not. After that we cut plexi glass and made tabbed box where we will put servo for the rotation of base. We designed the gears and cut it on styrofoam.

 

What we didn’t do:

We could not finish cutting gears in plexiglass. We are going to make gears, base platform for the top design using plexiglass this week and we have already designed it in inkscape. 

We will try to build the top part of our design this week.

Where we are stuck:

We have to put the things ( box, gears, servos, base platform, turntable ) together this week and we are working on that.

Notes/Misc:

Blue Team – Progress Report II for Prototype II: Smart Cushion

Goals for the week:

Our equipment has come in and now we are going to take the parts that we need from the assemblies and get them to work with the cushion that we got from Greg.

Meeting times/dates

Sunday 11am at Wallace Hall.

Individual Hours:

Approx. 1 hour each: Searching for appropriate pumps for our needs.

What we did:

We have taken out the pump assembly that was inside of the apparatus that it came in.  After we got all of the pieces we needed out of those we created “shields” for our arduino to use the pumps with transistors.  We also cut off the front part of the cushion to expose the four chambers to attach our assemblies to.  Finally we tested our assemblies to make sure that they worked.

What we didn’t do:

We have not yet connected our assemblies to the cushion as we do not yet have the appropriate barb connectors.

Where we are stuck:

At the moment we just can’t go any further until we get the appropriate connectors for the cushion.  We also need a new pump as the ones that came in the assemblies we purchased do not have nearly enough power for what we require.

Notes/Misc:

A Team – Progress Report II for Prototype II: Micro Cyber Watch Dog

Goals for the week:

1. Get all components by this week, still waiting on 1 xbee(we already have it 4/8).

2. Order batteries

3. Order new camera if was not possible to modify existing camera.

4. Research gear manufacturers, get quotes…..

5. Try to make a 2d/3d movie demonstration for open house.

Meeting times/dates

4/3/2013 @ 7PM, Electronics Lab Wallace Hall 3rd Floor

4/8/2013 @7PM, Electronics Lab, Wallace Hall 3rd Floor

Individual Hours:

Hector: 1 hr practice with Adobe Flash for 2d movie.

Gustavo:3hr practing with eagleCad, 1/2 researching the best battery, 4 hr playing with arduino mini, 5 hr developing Atmel microcontroller board.

Brandon:

James: 40 minutes. Got in Contact with Rick Shipman.  Rick is researching some ideas.  Rushgear.com CATIA files are in CATIA R22.  WSU lab and home computer not up to that release. Downloaded STEP files instead and assembled gear assembly just in case order from rushgear. Quote from Rushgear is about $1000 per Gear!  Plan B. Found a set of brass gears from usahobby.com.

What we did:

By now, 4/8 we have all components except for the batteries. We have already done some research for the small gears. We got two quotes from two difference places, one for 199.92 (8 gears) and another one way more expensive(about $1000 for each gear, we need eight). We already know what needs to be modified in the previous code for the Arduino nano, the actual programming has not been done since we had been waiting for the other Xbee. We are planning on doing a 2d/3d movie demonstration of what the bot is supposed to do for the open house. We have already opened the existing camera, and we have decided that we can used it for the project, so no need to order a expensive camera. Finally, because of the time constrains we don’t think that will be possible to replace the gears in the bot. 

What we didn’t do and we’re planning on doing the following week(s):

0. Get the batterie(s).

2. Program the Xbees. 

3. Create PCB.

3. Mount the wireless camera to the existing microbot (the smaller blue bot). Also, mount everything that needs to be mounted.

4. Start working on the visual display for open house.

5. Make the communication between the Controller board->Xbees->Arduino Nano->motors.

6. Make 2D/3D movie demonstration of what the microbot does…

Where we are stuck:

We are doing OK,..

BitShifters – Progress Report II for Prototype II: Shelf Assist

Goals for the week:

  • Meet with Rick Shipman
  • Adjust motor so that it fully lowers and raises

Meeting times/dates

  • Tuesday, April 2 – After meeting with Tom
  • Thursday, April 4 – Meet with Rick Shipman

Individual Hours:

  • Shanto – 4 hours
  • Andrew – 4 hours
  • Jeff – 3 hours
  • Ibrahim – 3 hours

What we did:

  • We performed some load tests on the shelf with the motor.
  • We met with Rick Shipman at the Cessna Lab. He gave us a piece of metal that can be used to alter the placement of the motor.
  • We drilled several holes in the metal piece to attach to the motor.

What we didn’t do:

  • Even with the metal piece, the motor still doesn’t fully extend the shelf.

Where we are stuck:

  • Is there a way to have the motor fully extend the shelf, while still being able to retract the motor all the way in?

Notes/Misc:

Eh Team – Progress Report II for Prototype II: Universal Wheelchair System

Goals for the week:

Try to get the tablet to communicate with the Arduino

Purchase Poster board and begin designing display for Engineering Open House

Meeting times/dates

Sunday 2-4

Individual Hours:

Ali: 5 hours

Cody: 1 hour

Imran: 1 hour

Kishor: 1 hour

What we did:

We finally determined the greatest stumbling block in our communications between the tablet and the Arduino.  We determined that the code we were using would only work with  Arduinos that have with Atmega16U2 or Atmega8U2 programmed as a USB-to-serial converter; however, it appears the Arduino we are using instead uses a FTDI USB-to-serial driver chip.  (However, when we check, it appears as though our Arduino should have the Atmega8U2, at least.)  Once we made this determination, we were able to run a sample app that allowed basic communciation between the tablet and the Arduino, in which the tablet displays the voltage detected at pin 1.  Also, we have purchased the poster board, and have began designing our display for the Engineering Open House.  We were also able to verify the vendor ID and product ID of our Arduino (view screenshot below).

What we didn’t do:

We have not yet been able to send data from the tablet to the arduino.

Where we are stuck:

Why the only app we are able to run on the Arduino is the one meant for an Arduino with FTDI USB-to-serial chip driver; however, when we looked up the Arduino UNO R2, it indicates that it should have an Atmega8U2 USB to serial converter.

Blue Team – Progress Report I for Prototype II: Smart Cushion

Goals for the week:

Get the parts that we need ordered and implement a graph into our code that can change color according to input.

Meeting times/dates

Saturday, 11am in the Wallace Workshop ~2 hours

Individual Hours:

There wasn’t much in the way of work to do outside of our meeting this week besides getting the parts ordered which would be negligable.

What we did:

We edited our code to show 4 different squares when the code was run.  The input from the pressure on the cushion would increase a color value on one of the squares which would change its color to show real time changes in pressure.  We have also ordered a couple valve assemblies which should be here soon.  All in all it was not a busy week but when the parts come in there will be work to do.

What we didn’t do:

We haven’t gotten together with Greg yet about using one of his old cushions, he responded to our email and we are going to meet him on Wednesday for all of that.

Where we are stuck:

There hasn’t really been any tough work to be done so far.  This next week will probably show some more difficulty.

Notes/Misc:

N/A
