Meeting Minutes

  • Backhoe - Missing pivot, few details such as cylinder mounting are needed. A good strategy would be to build the items that we are for sure about, add legs. Marcin volunteered to draw the pivot cylinder mount in sketch up. Can start build of pivot parts - do a complete fab procedure (Dan has completed much of this on paper). Is there a way to tag team the fab procedure? Such as uploading pictures every 5-10 minutes for every step - and have the steps documented on paper or sketch up? Where is Rob on documenting the fab procedure? Rob needs (hurting ourselves with the phoenix message because there is no wording) some wording - description of how something is being put together. Dan will take notes on paper, capturing how the assembly is coming together.
    • Discussion about how to capture the changes to the step instructions as we are assembling the product. Reviewed the work instructions that Rob produced.
    • Outcome - Phoenix method needs to have steps written underneath each picture - the technical expert (the person who designed the product needs to write the step instructions) During the build, issues and confusing steps need to be updated for laymen understanding simply using pen and ink.
      • Small issue - Dan's step instructions are handwritten - rather than transferring them to a typed version, we will move forward with the handwritten instructions - Dan will transfer it online later (time issue, Dan has to leave tomorrow).
      • Big change - Discussed writing everything down - Dan is game to write everything down
    • Cody - Feet, Dan - Bolts, Marcin - pivot mount

Thurs, 10 Oct 2013

Agenda:

  1. Backhoe Status: 1) Pivot 2) Stick - motion analysis, 3) Quick Attach - Concept Drawing
  2. Documentation Status
  3. Microhouse
  4. Ironworker: 1) Development board(s), 2) Problem Statement, 3) Outstanding tasks for remote collaborators


Backhoe Status

  • Legs
  • Pivot: James W. sent model that mounts the hydraulic cylinders -- need to review it, looks good upon cursory review and determine integration points
  • Quick Attach mount -- mostly done; may need to punch holes; need to determine structural support around the quick attach
  • Need to do a ROM for the boom and pivot
  • ROM for the legs for 2ft of vertical motion; check fit for cylinders
  • Need BOM, work instructions


Dcoumentation

  • Emmett is exporting and working on LifeTrac 6 photo editing
  • Rob is focused on Dozuki LifeTrac documentation for Shuttleworth

Microhouse

  • Cody is working on the roof

ACTIONS

  1. Rob will work out a process to direct remote collaborators to real-time help with video and photo editing, instructions, etc for Dozuki...will try to gett his done for implementation on Monday

Sidebar Discussion Agenda: 1) Backhoe build & manpower, 2) Ironworker problem statement, schedule, design needs, 3) Stress analysis direction for the Backhoe

  1. Get Mark for the build on Mon-Fri next week & Mon-Tues following week
  2. Ironworker Problem Statement 1) Need to a guide and/or reinforced pivot to allow the arm to move straight vertically with no lateral movement, 2) The pivot needs to be mounted closer to the body to increase stability, 3) The pivot plates need to be bound closer together, 4) Design a punch element, 5) Need a work table with clamping mechanisms and integration points, 6) Design feet for more stabilization(angle mounted to the side).
  3. Ironworker Schedule: Ironworker Sprint on 15 Oct from 6-7pm CDT to get RCs to begin design work, will begin buildout NET Oct 23
  4. Ironworker Design Needs: punch element, table & feet; plus an infographic
  5. Stress analysis for backhoe: 1) Need cylinder force for the teeth of the bucket; 2) How much does it weight?, 3) Need force on each of the cylinders for the boom, stick and bucket at the beginning and end of motion. First, will need a completed design (due COB today, most likely)

Wrap Up Agenda: 1) Backhoe Design Status, 2) Documentation, 3) Other: Ironworker Sprint, Visa options

Backhoe - Legs are 70% done, when complete we can start work instructions for pivot & legs; quick attach needs to be complete, and need to complete the ROM for the boom & stick

Documentation - Emmett's animations look great; Rob is in the process of uploading to Dozuki; on Latakoo right

Ironworker - confirmed for 15 October, that gives 1 week to design, 1 to build / test

Visa Status - Cyril has concerns over coming on a tourist visa; researching requirements for a B1 visa under "Training"; a J1 visa is expensive and would takw time -- may not fit our mission as well as the B1; need to contact the Business Visa office tomorrow for more information

Documentation: Rob is flying in late Sun night and will either rent a car or stay in a motel near the airport; plans to stay 2-3 days for Backhoe documentation.

Wed, 9 Oct 2013

Agenda:

  1. Backhoe Status: 1) Pivot - Sketchup, 2) Stick - motion analysis, 3) Quick Attach - Concept Drawing
  2. Documentation Status

Backhoe - continue design & ROM analysis Documentation - Emmett will continue deconstruction analysis & Rob is working on Prezi

Wrap Up

  • Backhoe Status:
    • Pivot: Sketchup design is 95% done; BOM is next, then assembly work instructions, need to do hydraulics -- hydraulics should be 16" pin-to-pin
    • Quick attach: INW & interface piece
    • Found a design flaw -- there isn't enough space for the pivot cylinders; Dan is developing a work around
  • Documentation:
    • Emmett needs to re-do one animation for the deconstruction animation on the LifeTrac 6; its going to take a long time to export the clips though--Emmett is researching to see if there is a way to export a large batch vs individuals
    • Emmett's next step: edit & import photos to Trovebox via jpeg; needs resolution standard (must be at least 400x400)
    • Rob recorded the Prezi for The Feast
    • LifeTrac 6 Documentation: ready for replication -- wheels & cab; can ID what works and what doesn't
  • Logistics:
    • Prototyping material for scaled modeling; Audrey is going to Hammerspace on Friday to cut more materials
    • 10" Bolts from MoKan - won't be here until Wed / Thurs next week; workaround: use threaded rods and cut to size
  • Other: Cody had a fundraising idea for future Microhouse construction; Katie took notes and will develop

Tomorrow's Plan

  • Microhouse: Handyman Donnie bailed on us, we are going to pursue Labormax and operate within their confines

Tues, 8 Oct 2013

Agenda:

  1. Backhoe Status: pivot
  2. Microhouse Update: One DPV plus a temp worker (trying to get Mark), will work on the MH roof on Thurs
  3. Documentation Status
  4. Logistics: 1) Cylinder order, 2) Other parts that may be 'long lead' orders? (i.e. 10" bolts?), 3) Add'l Rapid Prototyping materials

Backhoe Status

  • Dan suggested using trunions cylinders may work; Marcin brought up issues with using these cylinders wrt sourcing: price & availability; may be able to modify existing cylinders through a weld which will negate adding a special part--may explore welding but there is a risk with welding as well.
    • Way forward: Pursue solution that is a single control that gives us 160-170 degrees rotation; draw in LibreCAD--perform analysis, build a scaled model--perform analysis; draw in SketchUp; contact Design Sprinter that offered to do stress analysis
  • Stick: need to do motion analysis
  • Quick attach: develop a concept drawing for the Quick Attach, need to design the "female" part that is mounted to the backhoe

Microhouse

  • Cody will lead roofing on Thurs

Documentation Status

  • Emmett will try and do the deconstruction animation today; he has been grouping appropriate parts within the cab
  • Rob will go through the video of the cab to break down into a script to assist Emmett's efforts; Rob is also working on a video of the MH

Logistics

  • Cylinder order: not yet
  • Long Lead parts: 10" bolts from MoKan x 100, 1" washers x 100
  • Prototyping materials: screws, 80 pages of what we have; what is the size (working area) of their laser cutter?
  • Additional prototyping materials: screws,


Actions

  1. Backhoe: Dan is working Trig analysis; Marcin is doing LibreCAD drawing; Cody is
  2. Modeling: Cody is grinding down screws for the 3D modeling
  3. Inventory: Cody is going to perform inventory
  4. Audrey will call labor max to reserve Mark or other for roofing
  5. Audrey will source laser cutting in KC - get info on system

Wrap Up

  1. Backhoe pivot status: Geomoetry C/W, starting Sketchup; Maercin is working paper models exploring other ideas, Dan completed 2D LibreCAD pivot drawing; Will need to reassess the part that attaches to the quick connect for integration issues
  2. Modeling:C/W, screws ground down
  3. Inventory: Cody inventoried all of the plates; we do not need to buy cylinders; will likely need more steel cut -- need to determine last due date for BOM
  4. Roofer: Donnie, a local handyman, is coming out on Thurs and will work with Cody.
  5. Laser Cutter source: Audrey is getting Hammerspace membership, calling for more details
  6. Documentation: Rob is still digitizing footage from MH, Roofing footage is done; Emmett is struggling -- difficult to control Sketchup animation--taking numerous attempts to gain a smooth motion.

Mon, 7 Oct 2013

Agenda: 1) Backhoe Status, 2) Ironworker Status, 3) Microhouse Status, 4) Documentation

Backhoe

  • Goal: Decide design vector for pivot by COB today via Tech Tree of Choices; begin 3D modeling of Design in Sketchup
  • Backhoe Pivot:
    • Using Laser cutter pieces to build a small scale pivot (blog input & newsletter topic)
    • Dan & Cody created a viable option that will give us 160 degrees of motion (goal is 180 degress -- 90 degrees on each side)
    • Industry standard includes additional control mechanisms on the side of the pivot to allow for additional ROM
    • Need to complete a Tech Tree of Choices to determine path forward
    • Need to use LibreCAD to do a quick 2D analysis of ROM
    • Does 180 degree ROM apply to industry standard Backhoes that do not use a gearbox? What ROM do they get?
    • Discussion on custom work: may integrate minor custom work into design to allow for greater ROM; need to include these as options for analysis of complexity
  • We have 8" and 10" cylinders; but they may not have the correct diameter cylinders; may need between 8-12" -- let's order what we need today
  • Backhoe Bucket:
    • Need to determine proper pin mounting


Ironworkwer

  • Tabled --Need to discuss with Marcin and roll into schedule


Microhouse

  • Microhouse: Need to finish roof...work this into Ironworker / Backhoe schedule; get additional manpower to assist with this from temp agency


Documentation

  • Trovebox - DPVs will need to use Rob's login to upload from smartphones
    • Need to create a DPV General User account so staff accounts are not compromised
    • Need to provide feedback to Trovebox for improvement; we are part of a beta-test...need to include youtube, vimeo, Dozuki access, LibreCAD for simple 2D design -- need instructionals
  • New documentation method -- 1) Explode the diagram; 2) Play it in reverse to create a dis-assembly to assembly using animation (i.e. the Phoenix Method w/ animation). Issue: capturing the animation on screen; need to work this out (Rob will work this and get back to us). If it works, they will try the cab.


Other

  • Emmett is likely leaving Saturday or Sunday
  • Time off -- If DPVs need some downtime, speak up!
  • Workshop cleanup
  • Media focus this week: Rapid prototyping capability using laser cut pieces
  • Meetings: 9am Daily Product Development Meeting; 4:30pm Wrap-up


Actions

  1. Work on animation and sequencing for documentation purposes and work out our methodology -- Rob & Emmett
  2. Tech tree of choices for pivot -- Cody
  3. Build pivot in LibreCAD for 2D ROM analysis -- Dan
  4. Order cylinders -- Marcin will order if needed
  5. Shop cleanup -- ALL prior to workshop work today
  6. Add info to DPV O&M Board: youtube, vimeo, LibreCAD, & Dozuki access -- Audrey (with Rob's help)
  7. Create a DPV General user account for Trovebox? -- Rob
  8. Integrate Tech Tree of Choices instructions / protocol into Dev Board -- Marcin


End of Day Wrap Up Agenda: 1) Status on actions #1-3, 2) Decision: #4, 3) Other issues, 4) Next steps

Status of Actions

  • Emmett needs the LFT 6 step instructions (Audrey to send from Gary's Log)
  • We will need to take each frame and string them together; need to create procedures process is refined
  • Used new capture program iShowU HD
  • Tech Tree of Choices: Backhoe Pivot -- Tech Tree of Choices
    • Used Coggle to develop Tech Tree -- need to work out Coggle integration issues with our wiki
  • LibreCAD update: just used pen & paper and cardboard vs LibreCAD--we have two ideas: 1) two controls/valves for increased range of motion, 2) Single valve with less range of motion. Next step is to use prototyping tools to build each and test the ROM.
  • Shop clean up -- some worked was done.
  • Rob will contact
