156B Week 10

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

• • Two segments assembled and controllable (Kevin N., Madatya).

  • Fabrication: Soldering and wiring connection for the two PCB Stacks was re-assembled and re-soldered (Kevin N., Madatya).

  • Control: Both segments operate. Now characterizing performance and optimizing parameters (Kevin N., Matthew)

Accomplishments from Previous Week

• • Determined the root cause for loss of communication between robot and PC (Kevin N.)

    • Electrical connection in between various pins for the PCB Stack were inconsistent

    • Accordingly, re-soldering of PCB Stack in areas where a DMM reads 0 Resistance was necessary

  • Retested two segments to confirm their performances (Kevin N., Madatya, Matthew).

  • Successfully calibrated and operated both segments (Kevin N., Matthew).

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

• • Meeting Sponsor on 3/12 to discuss goals for the rest of the quarter and to assess segment performance.

  • Pass signal to second segment serially (through first segment).

    • If successful, try to actuate two segments together.

  • Finish Final Report.

    • Finish Hardware, Kinematics, Control & Operation, Performance, and Conclusion.

  • Finalize website.

  • Finalize poster.

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

• • Each segment is prone to connection issues due to large quantity of solder joints.

  • Twisted segments, string lengths, and "black box" are affecting performance.

  • Lack of mechanical performance impedes shape control.

Resources or Information Required but not Available

Schedule

• • Gantt Chart

Budget (list amount spent and amount remaining)

• • Remaining: $498 ($502 spent)

Progress on Report and Webpage

• • Report: Close to finishing. New edits being incorporated (whole team)

  • Webpage: Close to finishing; need to fill in further information once characterization of the two segments is completed (whole team).

  • Poster: Nearly finished (pending feedback). (Kevin N., Matthew).
