Activity 3.1.4 Branch Fuctions

1. Create program with two switches so that they will turn on a lamp when one switch is pressed and turn off the lamp when the other switch is pressed
2. Run the program

1. Wire the potentiometer and turn it counter-clockwise until it stops
2. Test it: the box next to the input reading became checked and unchecked and the number switched between 1 and 0.

Activity 3.1.3 Basic Programing

Procedure

1. Construct a flowchart that will turn a motor on and off. Using RoboPro software.
2. Test the system to see if your flowchart performs as written.

Part I:

• Start program
• Make motor start
• Insert time delay for 3 seconds
• Motor resumes
• Make motor stop
• End program

Part II:

• Start program
• Make motor start
• Run 2 seconds
• Stop for 2 seconds
• Run for 2 seconds
• Make motor stop
• End program

Activity 3.1.2 Flowcharting

Shape Meanings

Procedure #1

Procedure #2

Procedure #3

• How is flowcharting similar to using a map to plan a route for a trip?

             You reach landmarks which you then decide where the next one is. Enabling quick successful stops until you reach the target location.

• Describe a process that you perform every day. Develop a flowchart that illustrates the process.

Activity 3.1.1 Inputs and Outputs

This activity was used as an introduction to our future robotic projects, and getting an understanding of how inputs and outputs work in both analog and digital formats.

We used Fischertechnik components including: Interface, power supply, and USB cable, RoboPro software, and some complete wires

Moments

This assignment featured us utilizing rotational tendencies(moments) to better understand the desire for rotation.

Manila Folder Bridge

Lauren, Conner and I worked as a team today for this design build challenge.

Criteria: Build a structure that can support as much weight as possible over a 18" gap.

**Magazines will be the weights and two separated tables will be the gap**

Constraints Part I:

Materials:

• 2 Manila Folders (letter size)
• 2 feet of tape (may not use a piece of tape longer than 6")

Weighing: 

• Magazines will be used as "weights"
• Your "score" for our competition is determined by how many magazines your structure supports!
• Magazines will be added to your structure one at a time until "failure" is achieved
• You may place magazines anywhere on your structure as long as:
• All magazines must rest between the two vertical edges of the gap your bridge is spanning (magazines must be over the "gap")
• No magazines may tough the tables (magazines may not be piled up to "self support themselves)

Construction Practices

• Only one end of your design may have a "pinned" connection to the table top (i.e taped). The other end must act as if it were on a "roller" connection (i.e. laying on the table top).
• Manila folders may not be layered more than 3 layers thick at any location.
• Parallel structural members may not touch directly (they can be connected via non parallel connection members (ex. a "ladder" style design))

Our Design:

• Plan 1: fold the manila folders into thirds and place them across the gap connecting them with a few folded strips in the center
• Plan 2: make a design like the bed of nails on Mythbusters- make a lot of little pyramids out of one folder and then tape them all over the other one that is spanned across the gap to try and distribute the weight of the magazines
• Plan 3: use the manila folders and fold them into thirds and create a triangular prism place them side by side separated by two inches across the gap
• Final plan: make the folders into triangular prisms and put one inside the other across the gap

We managed to somehow get 50 magazines on our structure for a brief second before we failed.

Beam Deflection

Beam Deflection

My team members were Corin, Conner, Conner, Quinn, and Mark. Using a 2x4, a few phone books and magazines, and a measuring tape we would use beam deflection to try to calculate the weight of a group member.


Mark was our first attempt

Conner L. was our second attempt

It was pretty cool to see how close we could get to the actual weight of the person.
