Marble Sorter - Submitted Materials


· Cover Page - Project title, your name, partner's name, course name, date, etc.?


· Initial sketches – You will conceptualize your design and prepare a quality sketch of your system. This will be the concept you develop to completion.


· Program Narrative – A written step-by-step description of how you want your team’s marble sorter to operate. Include your motor ports, switch ports, analog input ports and associated values. Be as detailed as possible.


· Daily Entries – Every day keep track of your progress. Your entries must be made in the following form.

o Date:

o Tasks yet to be addressed

o Tasks Accomplished


· Print out of Program – A copy of the RoboPro program, and each subroutine in that program, will be copied to Word. A written description of each part of the program will need to be included.


· Device Pictures - You must include a series of photographs of your marble sorter.

o Side - Front - Top

o Orthographic

· Reflection - Write a one page reflection about your design. What worked well? What was problematic? What would you change? How well did your group work together?

IRobot


Answer the following questions by Monday morning:

  • 1.) If in the future machines have the ability to reason, be self-aware and have feelings, then what makes a human being a human being, and a robot a robot?

  • 2.) If you could have a robot that would do any task you like, a companion to do all the work that you prefer not to, would you? And if so, how do you think this might affect you as a person?

  • 3.) Are there any kind of robots that shouldn't be created? Or that you wouldn't want to see created? Why?

  • 4.) Automation and the development of new technologies like robots is viewed by most people as inevitable. But many workers who lose their jobs consider this business practice unfair. Do you think the development of new technologies, and their implementation, is inevitable? What, if anything, should we as a society do for those people who lose their jobs?

Fluid Power Wrap-Up

Yeah... I thought you'd go for a take home quiz...

To conclude our work on fluid power, I'm going to let you guys do some of the fun stuff...

Your assignment:
  • Due first thing on Monday (02.09.09)
  • Write a "test-style" question for each of the 4 Fluid Power Laws.
  • Each question must include a clear problem statement and a diagram.
    • example:



.

Fluid Power

Today's assignment is NOT to be done in groups:
  • Draw a schematic diagram (single view, not to scale) of your group's fluid power system.
  • Label all of the items, subsystems, elements, and other stuff in your diagram.
  • On a seperate sheet, write a paragraph about how the fluid power laws fit into your system. Consult the PowerPoints that I handed out for details on the laws.
btw: Your PoierPoints should be completed for tomorrow.
