156B Week 3

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

• • Keep researching on how to implement the constant curvature continuum simulation.

  • Sheath design is in progress and should be finished by the end of this week.

  • Circuit tests will be performed to confirm the circuit diagram. The circuit diagram will be finished by the weekend.

Accomplishments from Previous Week

• • None.

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

• • Finish circuit diagram.

  • Get the first segment working.

  • Start fabricating segments.

    • Machine parts.

  • Begin single-segment simulation.

  • Finish sheath design.

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

• • Comment via email(1/22/19):

    • Start full 3D simulation with multiple segments ASAP.

  • Actions Taken:

    • Continued research and development of simulation.

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

• • Dr.T asked how the string actuation works and how it could help bend the segment? (1/17/2019)

  • In addition, the TA also have asked regarding the circuit diagram? (1/17/2019)

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

• • One of our peers asked about the effect that the motor has on the IMU? (1/17/2019)

  • They have also asked how could the robot be continuous when there is a rigid body in each segment? (1/17/2019)

Risks and Areas of Concern

• • Completing the 8 segment assembly fast enough to implement control by week 10.

Resources or Information Required but not Available

• • Awaiting parts.

Schedule

• • Describe the upcoming milestone

    • All team members are required to fabricate eight segments after the circuit diagram is finished and doing research to speed up the project pace

    • Fabrication has to be completed within 2 weeks (barring any major complications).

• Update Gantt chart

Budget (list amount spent and amount remaining)

• • No new orders

  • Remaining: $498 ($502 spent)

Progress on Report and Webpage

• • Will update and correct week 2 assignment (mainly Background and Existing Solutions), and post it by the end of this weekend.

  • Working on 4 aspects of Impact on Society (medical, search & rescue, exploration, robotics).
