Week 3

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Track type decided (snowmobile parts). Budget for UCSD is $500.00 at the current moment and waiting for more information about further funding.

  • Frame decided and further analysis implemented into design.  Tensioner design is pretty much set, unless new ideas provide advantage with proper analysis.

  • Segway basic robotic platform taken to campus for full access of all team members.  Waiting for controls for the Segway and looking to work all dimensions when tracks arrive.

  • More analysis about the splicing of snowmobile tracks (perhaps scheduling time with Tom to talk about it).

Accomplishments from Previous Week

• • Created a cleaner website/feasibility (Ed. Siddiqui)

  • Researched Snowmobile tracks (Ryan)

  • Purchased drive wheels/drive shafts/tracks (Ryan)

  • Researched Chain Tensioner Designs (John)

  • Drive train gear ratio calculations reworked (Mahin)

  • Researched track splicing and belt lacing (Ryan & Ed)

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Send orders for raw materials & COTS parts to Aaron at SPAWAR (All team members)

  • Begin feasibility testing, Website Updates/Construction  (Ed)

  • Rework designs of custom parts based on COTS parts' dimensions (John, Ryan, Mike)

  • Rethink track tensioner designs based on sponsor opinion

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments

• • Expressed increased support for a single-pivoting bar track tensioner over the barred-link design.

  • Reiterated that stock Segway parts must be unaltered so that the track kit is reversible

  • Wanted us to research more into track geometry design to chose a proper lead angle and length

Instructor Comments from Last Meeting and Actions Taken to Address these Comments

• • Discussion of ideas of frame design 

  • Some confusion about purchasing clarified

Risks and Areas of Concern

• • Purchasing from ebay.com reduces cost immensely, but is difficult to account for in purchasing bureaucracy

  • Unable to run full-scale tests without a robot controller

Resources or Information Required but not Available

• • N/A

Schedule

• • Update Gantt chart.

Budget (list amount spent and amount remaining)

• • $6000 provided

  • $270 spent

  • $5730 remaining

Progress on Report and Webpage

• • Home and Reports pages reformatted and organized

  • Added links to sponsor and updated project management page (w/ video embedded)

  • Beginning report organization
