156B Week 1

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

• • Analysis of tube from tests

    • Tapered edges provided deeper penetration depth when pressure is applied. However, edges that are too tapered might break and cause injury  

    • Smaller Tube should have sank deeper due to having less surface area sliding through the soft sediment

    • Type of Sediment varied tube results greatly; Packed sediment and rooted sediment proved a tough challenge for tube to go through

    • Other obstacles discovered are that shells and other debris embedded in the soil got in the way of tube sometimes

    • Vibration device or some sort of mechanism that loosens soil & debris should be implemented

Accomplishments from Previous Week

• • Risk Reduction Data Obtained

    • Pressure Required to sink tubes to a certain depth in different sediment types/conditions

  • Powerpoint presentation of Risk Reduction Complete

  • Planned Bi-monthly meeting dates/time with sponsor for Spring Quarter

    • In person for one week and phone call other week

  • Planned Weekly meeting dates/time with team for Spring Quarter

  • Project Gantt Chart/Milestones Complete

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

• • Individual Component Analysis Complete (Analysis Reports/CAD if needed)

    • Visual Processing (Josh)

    • Trigger Mechanism

      • Electrical (Caitlin)

      • Sealing (Denny)

    • Cameras/Reflective Tape (Justin)

    • Extendable Rod/Strainer (Isabel)

  • Convene and discuss design ideas

  • Complete Design Proposal Presentation 

    • A brief overview of the problem definition (1-2 slides). (Joshua)

    • Review Risk Reduction that has been completed. (Caitlyn)

    • List of key design decisions that have already been made, and explain the justification for these decisions. (Justin)

    • List key design decisions that still need to be made. Present a plan and timeline for making these decisions before the Proof-of-Concept Presentations in Week 6. (Justin)

    • Summarize the proposed design that the team plans on implementing. (Denny)

    • List major components that need to be purchased, and a timeline for placing the purchase orders. (Denny)

    • List key items that need to be machined, and feedback from shop engineers (Ian Richardson and/or Tom Chalfant) regarding timeline and feasibility. (Isabel)

    • List remaining questions and concerns that need to resolved (Isabel)

    • Show a Gantt chart with task assignment for the rest of the quarter. (Joshua)

  • Post ICA on webpage (Joshua)

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Team has looked at past project website and design

  • Team has tested the amount of pressure needed to sink tube into different sediments

  • Team has yet to look into

    • Smaller Cameras

    •  IR Vision

    • Method of implementing 40 intersection quadrant

    • Method of measuring wet weight vs. dry weight algae

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • Recommended team to reference past team website/project

    • Team has already done so and will do so

  • Recommended a mechanism of sinking the device into the soil

    • Water chamber idea which when filled will sink device to the bottom of the water channel

  • Recommended a mechanism of loosening up soil if obstacles(shells/roots/other aquatic objects) get in the way of tube

    • Tube vibration mechanism which will produce vibrations loosening up soil/other debris

    • Tube cutting mechanism which will push obstacles out of the way by rotating the tube mouth

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • N/A

Risks and Areas of Concern

• • Time/Budget constraint of adding mechanism to loosen up and dig through sediments/aquatic obstacles

Resources or Information Required but not Available

• • Manufacturer contact info

Schedule

• • Individual Component Analysis to be complete by Midnight on Friday 4/7/17

  • Phone Meeting with Sponsors on Friday 4/7/17 at 10 a.m.

  • Chuck broke his leg which resulted in phone meeting

Budget (list amount spent and amount remaining)

• • $0/$1000

Progress on Report and Webpage

• • Gantt Chart Added to Webpage
