Myles’s Status Report for 2/24

Personal Accomplishments:

  • Lab Meetings (4 hrs):
    • Attended section’s Design review presentations and gave constructive feedback
  • Team Meetings (6 hrs):
    • Wrote the design review slides and finalized details for MVP
  • Research (2 hrs):
    • Looked into PWM through Arduino and found scripts to output PWM to the input pins of the h-bridge
    • Worked on a simple LED circuit to showcase PWM and the ability to raise and lower the duty cycle for the LED

Progress:

Behind Schedule – We need to change our CAD design for the carrier and track and have not made as much progress regarding propulsion. This week we worked with a cardboard prototype to see the feasibility of levitation and achieved a levitation of over an inch.  We will be doing the CAD development of the track and carrier in parallel with the H-Bridge circuit.

Next Week Deliverables:

  1. redesign track and carrier with connection grooves for increased stability
  2. Implement PWM for the input pins on the H-Bridge to create the propulsion force

Myles’s Status Report for 2/17

 

Personal Accomplishments:

  • Lab Meetings (4 hrs):
    • Discussed with TA and Professor the details of the proposal and cleared up design choices for MVP
  • Team Meetings (4 hrs):
    • Worked on Design Review Slides and updating gant chart with updated tasks because of tweaked design for MVP
    • Decided to move away from RFID sensors and digital potentiometer.
    • Finished CAD prototype for carrier
  • Research (4 hrs):
    • Researched H-Bridges, magnetometers, and ultrasonic sensors as alternatives for our proposal design.

Progress:

Behind Schedule – The schedule will be updated to reflect setbacks. We should have progressed with the coil circuitry this week but we needed to refine our design to meet our use case requirements. We initially were not sure about how we were going to implement obstacle detection and had mentioned LIDAR sensors in our presentation we decided to go with an ultrasonic sensor to make things simpler. We also decided not to use an RFID configuration to gauge user input as this was clunky and generally not what RFIDs are used for.

Next Week Deliverables:

    1.  Finish track CAD prototype
    2. Order magnets, sensors, 3D filament
    3. Start coil circuit try and Arduino voltage input

Team Status Report 2/10

Team Status Report for February 10, 2024

Risks

  • Levitation not working. 
    • We have a backup system with mechanical wheels. We will test the levitation system early on to make sure it’s sufficient 
  • Things ordered don’t show up on time
    • Working in slack time into the schedule. 
  • Integration not working out. 
    • Prioritize levitation and propulsion and work with the functional components. 
  • Speed and Slow not Implemented. 
    • Try different methods to implement speed-up/slow-down, we’ll look into different tracks and circuit designs. 
  • RFID stops not functional. 
    • We’ll make sure the train does a complete loop around the track which can be triggered by the user. 

Design Changes

The LiDAR may be changed to an ultrasonic sensor or something lighter and simpler. The LiDAR may be too complicated for our needs. 

Schedule Changes

In the future, we will try to make it more clear that our tasks are parallel.
