Team 6 (3!) – Progress Report I for Prototype I: Mechanical camera stand control system for wheelchairs

Goals for the week:

  1. Finalize our mechanical design and list out the parts required for the project.
  2. Get familiar with arduino.

Meeting times/dates

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

Individual Hours:

All the members of the team will do research on the parts required for the project.

What we did:

Tuesday 02/12/13:

We went over the meeting time, assigned the roles and worked on code of conduct for the team. We briefly discussed over the design of the project.

Thursday 02/14/13:

  • We started our meeting by testing a servo controlling with a potentiometer using arduino uno and a bread board. We went over the interface of the software arduino 1.0.3 (sketch)  and tested the servo with some examples from the software utilizing the header file servo.h and observed how we can specify the rotation of the servo in degrees in the example code.  
  • We discussed over the mechanical design for the project and had a challenge on locking the vertical shaft that moves up and down. To over come this problem, we thought of using a solenoid that will push or pull a lock system into the vertical shaft. Solenoid and the lock system will be mounted on the base so that the vertical weight of the shaft is handled by the lock system which would be  pushed or pulled by the solenoid. We figured that we will need to make a small track to align the lock system and solenoid. We found a solenoid that might do our job -  https://www.sparkfun.com/products/11015
  • We went over the parts that are required for our project which are:
Quantity Parts required Estimated Price Resource  for parts
2 Servos (180 degree) 27*2= $54 ? HS-485 ? HB, http://www.servocity.com/html/hs-485hb_servo.html
1 Servo (continuous) $51 ? HS-645MG ? , http://www.servocity.com/html/hs-645mg_ultra_torque.html
1 Used camera tripod $20-$30 Craigslist
1 Bearing ball turntable $7 http://www.servocity.com/html/ball_bearing_turntables.html
1 Hinge ? ?
1 Fixed platform ? make it ?
1 Turning platform ? make it ?
1 Platform mounting + Hardware ? make it ?
3 Angle Plate ? make it ?
 2  Pins  ?  ?
 2  Movement arms  ?  ?
 1  camera mounting screw  From tripod  From tripod
1  gear  ?  ?
 1  arduino uno From lab  
 1  3-axis joystick? or two 2-axis joystick  ?  ?
 2  Limit switches  From tripod?  
3 Aluminum Sheets ? ?

 Estimated total price: $140-?

Estimated weight including vertical shaft ~ 3 lbs.

 

 

What we didn’t do:

  1. We are still looking for the parts that we need.
  2. We  need to calculate the weight and torques involved in the design.
  3. We need to visualize the design part of our project either through catia or using a box model?
  4. We need to finalize what are the parts that we can find and buy and what we need to build so we can start ordering them or building them.

Where we are stuck:

  1. Is there any alternative method for locking the vertical shaft that goes up and down ( We are thinking about solenoid..)
  2. Finalizing the parts required for the project, help from some mechanical guys!

Team 5 – Progress Report I for Prototype I: Shelf Assist

Goals for the week:

Meet with CPRF.

Examine shelves inside resident appartments.

Discuss materials needed for Prototype I.

Start gathering materials and assembling mechanical structure.

Meeting times/dates

Tuesday, Feb. 12 – 7:00pm to 8:30pm – Wallace Hall

Monday, Feb. 18 – 9:15am to 10:00am – CPRF meeting with Tara Person

Individual Hours:

Andrew – Contacted Tara @ CPRF.

Ibrahim – Researched lowering shelf designs, looked for materials.

Jeff – Researched lowering shelf designs, looked for materials, checked out Arduino from lab to begin familiarization.

Shanto – Visited with Tara @ CPRF, researched lowering shelf designs.

What we did:

Discussed materials for Prototype I.

Met with Tara at the CPRF. Looked at shelves inside the residents’ apartments.

Drew up a design for the lowering system, and determine what structural materials would be best and most accessible. 

What we didn’t do:

Gather materials.

Start assembling mechanical structure.

Where we are stuck:

 

Notes/Misc:

Residents have standard cabinets with adjustable shelves.

Blue Team – Progress Report I for Prototype I: Pressure Regulating Air Cushion

Goals for the week:

Assign duties to each member of the group and get the parts we need ordered.

Meeting times/dates

Set Meeting Date: Saturday 11 AM

Optional Meeting Dates: Mon, Fri 9AM, Sunday 11AM

Individual Hours:

1 hour meeting where all members participated

20 minutes Brian and Jared put a list of items together and ordered the parts

20 minutes Travis wrote up the Code of Conduct and filled out the Progress Report

What we did:

At our meeting we went over some of the more technical aspects of what we will need to do for our prototype and made our code of conduct.  We also discussed about how we will want to have our final product and when we will be able to meet with Greg at CPRF.

What we didn’t do:

We haven’t had the chance to actually work on our design yet as we have just ordered the parts.  Next week we will be able to begin the prototype.

Where we are stuck:

So far we don’t seem to have hit any dead ends or snags, everything seems to be moving along smoothly.

Team One – Progress Report I for Prototype I: RPTC

Goals for the week:

Generate team names

Generate project name

Decide on prototype carousel rollers

Start carousel build

Meeting times/dates

Tuesday 12 Feb 2013 – After class, about an hour in work area

Friday 15 Feb 2013 – 3:30 pm, about an hour at BTCO

Saturday 16 Feb 2013 – 9:00 am, shopping for parts and building framework for about 2.5 hours

Individual Hours:

Miles – All meetings

Michael N. – All meetings

Michael M. – All meetings

What we did:

Met with Rich S. from BTCO to see what we are actually doing, measured table, got print sample. 

Discussed Non-Disclosure Agreement, it is just the customer information and actual prints.

Purchased 3/4″ rigid conduit and connectors for framework of project and did localized search for rollers for carousel.

Assembled framework from conduit. 

What we didn’t do:

Find carousel rollers, finalize carousel design.

Where we are stuck:

Which roller/wheels to use on carousel.

Camera to tell line measurement difference or just raw image. (Final product idea)

Notes/Misc:

Printed plots to measure can go up to 300″ x 54″.

If we can eliminate the need for the light table, that would make the project even more desirable.

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

Goals for the week:

The Product that is available in Market to be ordered and later analyzed for mechanism.

Meeting times/dates

Tuesday 07:00 pm to 8:30 pm Thursday 4:00 pm to 5:30 pm

Individual Hours:

Zubair Imtiaz – Documentation (Minutes of Meeting) and Research on the mechanism of the product. 

Nick -

Michael – Researched device and ordered one from Amazon. 1.5hrs

What we did:

Michael ordered the device and hopefully we will have it by our next meeting so we can start analyzing the product, probably do reverse engineering on it and figure out a way how we can extract ideas from different other devices that are available in market. We watched a couple of related videos on Youtube that can help us about how this device works before we have it in our hands. Also if we want to build this from start, how our design would be different from the rest of the similar devices out there that can perform the similar task. We also talked a little in out meeting about what things we want to accomplish with this device this semester and then take this project to next level in our Senior design 2 class, hoping we have a summer in between our classes so we can add some other features to this device. We also talked about getting in touch with the robotic team. Of all the different videos we saw about the similar product, none of the product have the capability to undo the cap of the bottle/jar, and we hope  there is no product out there in market that can do that :) , so that makes our project UNIQUE. As a team, we defined our roles on this project and our contribution for its success. So far we have achieved what we talked about except the device, but we will get our hands on it in our next meeting on this Tuesday  [02/19].

What we didn’t do:

We are still waiting on for the part/device.

Where we are stuck:

As soon as we will analyze it, we will talk to John, if there is something that is beyond our capabilities. We would like to work closely with Thomas since he has a lot of experience with circuits and stuff and his help would be beneficial for the success of this project

Notes/Misc:

Michael to Research on the compatibility of the Arduino. Next meeting objectives discussed already.
