 Objective for the week (3/31/2021 - 4/7/2021):


The objective for the week is to finish up developing the docking mechanism. Moreover, our objective is to complete as much as we can to present our updates on April 7th. Currently, the docking mechanism is fully functional with the dashboard. The dashboard is able to show indicators that explain the actions of the linear actuator. The team wanted to reorganize and compact the circuit and wiring so it would be easier to package it in a container. We attempted to compact the circuit and wiring on a PCB board however, we were unsuccessful. We decided to keep our circuit and wiring on a breadboard to prevent wasting more ESP32 boards. The team managed to test the docking mechanism on the bogie, specifically determining how the linear actuator will grab the bogie. The bogie will have a similar magnet that the linear actuator is using. This will allow the magnet of the linear actuator to grab the bogie by attracting the second magnet.


Individual tasks:

  • Pedro Serenini:

    • Mount the docking mechanism on the superway track.

    • Create a CAD model for a box that will contain the electronics.

  • Yit Voon Yap (Nick):

    • Mount the docking mechanism on the superway track.

    • Compact the circuit and wiring of the docking mechanism.

  • Phuc Tran:

    • Continue developing a dashboard/control panel for the charging station.

    • Use SolidWorks to demonstrate/create the docking mechanism.

    • Further develop the dashboard to monitor voltage and current of the 12V batteries used for the charging station.

      • Further develop the dashboard to output this data through mqtt.

  • Jacob Villanueva:

    • Track the progress of the IoT team.

    • Prepare slides for presentation #2.



Individual progress:

  • Phuc Tran:

    • Utilized Influxdb (database) for the Node-RED dashboard.

      • Data can now be stored in a database.

    • Created a scaled CAD model of the track to demonstrate the placement of the docking mechanism.

      • Will continue to work on the mounting.

    • Assisted compacting the circuit and wiring on a PCB board.

  • Pedro Serenini:

    • Created a CAD model for the box that will contain the electronics.

      • Will continue to develop the box design after circuit reorganizing is done.

  • Yit Voon Yap (Nick):

    • Created a 3D printed part that attaches the linear actuator and magnet together.

    • Compact the circuit and wiring of the docking mechanism.

      • Will return to using the breadboard since several ESP32 boards were burned.

      • Ultrasonic sensor broke when we attempted to compact circuit and wiring on a PCB board.

        • Will fix this issue next time we meet at the design center.

    • Further developed the code for the docking mechanism.

    • Utilized buck converter so the electronics can be powered by a 12V power line.

  • Jacob Villanueva:

    • Used Solidworks to create a CAD file to make the 3D printed mount part for the bogie so that it can hold the second magnet.

    • Fabricated L-bracket that will attach the 3D printed mount and magnet onto the bogie.
