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

Goals for the week:

Finally get our hands on the device and reverse engineer it to find out about the mechanism and decide whether we must follow the same mechanism with changes desired or built it from the start

Meeting times/dates

Tuesday 07pm to 08 45 pm. No meeting on Thursday due to weather 

Individual Hours:

Zubair – Research on AC/DC motors. Discussed the idea with a  friend of mine with mechanical engineering degree who can help us with design as well as CATIA drawings if we need any.

Michael -

Nick -

What we did:

After out meeting with Thomas on Tuesday we showed him the device and tried to uncap a few bottles. Honestly the device was a wastage of money so we planned on building a similar device from the start. To find the mechanism of this device we unscrewed it and analyzed how our device can be different and well equipped and at least better than this. We planned to use DC motor instead to reverse the direction of the current and use a solid base that can rotate and uncap the bottle. Also we planned on working on the motor in our next meeting.

What we didn’t do:

We didn’t work as planned for our next meeting due to severe weather on Thursday and so have to postpone our meeting.

Where we are stuck:

We can have better idea today when we actually start working on it.

Notes/Misc:

Meeting times/dates

Tuesdays and Thursdays every week @6 pm – 2nd floor, Wallace hall lounge.

Individual Hours:

  • Bill will work on catia drawing
  • Kusai will look for tripod and buy it
  • Rupak and Saeed will work on arduino and servos and order solenoid

What we did:

  • Opened Bill’s tripod and studied the gear mechanism for the vertical shaft of the tripod.
  • Solenoid ordered
  • Kusai is looking for Tripod
  • Opened a joystick (2-axis) from a Remote Control to be used for pitch and pan for the prototype I
  • We have decided to use the servo available in our lab and use it in our mechanical structure for the first prototype.

 

What we didn’t do:

Due to whether we could not meet in our scheduled time. Bill is still working on design.

Could not test the joystick with the servos (To be done Tuesday and Wednesday)

Building the Mechanical structure was not started (To be done This week)

 

 

Where we are stuck:

We could not meet last week. We have not started building mechanics.

Team Deliberate Gecko (1) – Progress Report II for Prototype I: RPTC

Goals for the week:

Acquire box to make into carousel housing.

Acquire carousel glides.

Acquire carousel rails.

Make/get X-axis frame rollers.

Meeting times/dates

Saturday 23 Feb 2013 – 9:00 am, work on carousel assembly, y-axis rails, rollers.

Individual Hours:

Miles – 3 hours Saturday

Michael N – 3 hours Saturday

Michael M – 3 hours Saturday

What we did:

Drilled out caster wheel pins to get the rollers to use on X-axis frame, and then made the brackets that will hold the rollers.

Acquired a few boxes for use as carousel housing.

Acquired square aluminum for Y-axis rails.

Acquired bolts and nylon locking nuts for the X-axis frame rollers.

What we didn’t do:

Put the Y-axis rails together.

Put the carousel gliding rails on.

Assemble the roller brackets.

Where we are stuck:

We need to find appropriate size/power stepper motors.

Notes/Misc:

The Yard is a pretty great place to shop for parts.

Eh Team – Progress Report II for Prototype I: Wheelchair API

Goals for the week:

by March 12 we will have as the Prototype I a simple App on our tablet which will open and close retractable table

 
 To do this this week we will:
  • decide on a low-level communication between arduino and android:
  • set up github
    • make public and give links in this report
  • start googledoc of API
  • get the arduino
  • talk to Rami and Sushila and study the retractable table report. Get the table working again as is.

Meeting times/dates

Sunday 2:00-4:30

Individual Hours:

Ali:  2 Hours

Imran: 1.5 Hours

Kishor: 1 Hour

Cody: 1 Hour

What we did:

We set up a repository in github, which can be found at: git@github.com:bouhouch6/WheelChairSystemApp.git and another at git@github.com:bouhouch6/WheelChairSystemArduinoCode.git.  Also, we created a Google Doc at: .  After studying the different possibilities for low level communications, we decided to start by trying to use the USB connection, found at the link above, entitled “Another Possibility?”  We also each checked out an Arduino Uno, and began playing around with them in an attempt to better understand how to use them.

What we didn’t do:

Notes/Misc:

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

Goals for the week:

  • Interface a button to the arduino. Turn serial data on/off
  • Hook up two potentiometers and get the values printing to the serial port.
  • Get Processing to output the data coming in from the serial port:
    • sensor 1: XXX  sensor 2:YYY

Meeting times/dates

Sunday 11am-3pm

Individual Hours:

.5 hours: All group members individually introduced themselves to the Arduino micro-controller before the meeting.

What we did:

Got arduino interfaced with computer. Completed a program that can read data from 2 or more potentiometers (or other analog voltage sources) and outputs this data via serial. We also wrote a program in processing to interpret this data and store it in appropriate variables.

What we didn’t do:

We need to just continue working with processing to see what else we can do with the data. Maybe check into libraries for making graphs with our data. Also, still need to make a shared dropbox folder or something for easy access to our existing code.

Where we are stuck:

Waiting for parts to come in. This mainly inclu

 

des the cushion and sensors. Once these come in we should be able to make significant progress on the hardware portion. ETA: Sometime this week.

There could be improvements we could make in our serial protocol implementation.

There are some concerns about how reading the serial data in processing actually works and whether we will “get behind” in reading data from the arduino with our current implementation. Check to see if there is a more ideal implementation of reading and manipulating serial data in processing. We should see if John or Tom have input on this, or we can post to the Arduino/Processing forums.
