20. Project development

Learning outcomes - Implement project plan

  • Apply time management techniques

  • Summarise and communicate the essence of your project development

WHAT TASKS HAVE BEEN COMPLETED?

  • Develop 2d design for body(frame) which will house PCB and mount all the necessary components like the bag value mask, compression mechanism and motors.

  • Develop 3d design for compressor piston, motor mounts, rack and pinion gear.

  • Develop PCB board schematics for the control for servo motors.

WHAT TASKS HAVE BEEN REMAIN?

  • Develop program algorithm for motors.
  • Total cost for materials and supplies.
  • Most important testing .

All the work done is summarized in documentation.

WHAT IS WORKING?

  • The frame design was adequate in house all component need.
  • 3D prints for motor mount, compressor piston , rack and pion gear .
  • PCB board for controlling motors .

WHAT IS NOT WORKING OR NEEDS TO BE IMPROVED?

  • Rack and pinion gear works well but could do with so improvement to design to eliminate a up kick in the compression stuck .
  • Only occurred to me after the design process to in include a on/off switch and an LED indicator light .
  • PCB may have to be redone to include more output/inputs.

WHAT QUESTIONS NEED TO BE RESOLVED?

  • Why motors are out of sync in compression cycle . which I know is a programming issue!

WHAT WILL HAPPEN WHEN?

For successful operation of the project

  • Complete algorithm for motors
  • Complete improvement if possible to include switch and led
  • Test the performance

WHAT HAVE YOU LEARNED?

  • Always place holes on PCB for ease mounting on sufaces
  • Design and prototype as quickly in order to time for improvements
  • Always include more output/inputs in PCB design just encase of add-ons
