156B Week 4

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

• • Prototype of water tank and transducer gate is almost finished. Some components need to be re-manufactured with different materials.

  • Components of drive train have arrived. We will work on motor control during this week.

  • Gantry is ready for manufacture.

Accomplishments from Previous Week

• • The problem between transducer connector and tube is solved. And performance of water tightness is good.

  • Timing belt is cut and fits well in the slot on the surface of water tank.

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

• • Overall our goal is to finish prototype as soon as possible:

    • Water tank and Transducer Gate (Shengkai & Shihao): Cut the hole on water tank which fits the transducer gate, 3-D print transducer holders with better printer and materials. Finish up all manufacture on this two components and assemble them.

    • Drive Train (Quan): Work on circuit and control of motor. Get familiar with motor operation and test the drive train system if possible.

    • Gantry (Qiaosong): Finalize the gantry design and manufacture it.

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

• • No sponsor meeting since sponsor is out of town. 

  • Progress of project is keep updated to sponsor via emails.

  • The goal is to finish prototype by the end of April when sponsor is back.

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

• • In class meeting (April 16):

    • Set-up always take more time than actual manufacture. 

      • We rechecked our design to make sure it's not too complicated to manufacture

    • If the motor cannot generate enough torque to rotate the water tank, deal with friction then.

      • We will test the drive train system to see how it works.

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

• • Space on the bottom plate is very limited. Positioning of gantry and drive train system may become a problem. 

  • Since drive train system has not been tested. We would rise concern about the performance of drive train, and we've already come up with plan B. 

Resources or Information Required but not Available
