Prop cars

We had a short amount of time to make our own prop cars. Fortunately, Kacie has made 2 other cars and knew what to do. She assisted in the formation of the car, the soldering, and the attachments. In the end, we made our car and it was able to go fast.

The Smokey Sorter

Along with our short programming section, we launched ourselves into the capstone project, Marble Sorters! I worked with Kyler Smith, Israel Dedina, Wes Ahrens, and Chase Fischer. We worked a long time on this and eventually came up with a working model that sorted 3 marbles.

We Earned 20 Achievements.

Reflection
+: We successfully sorted 3 marbles
     We sorted the marbles very quickly
      It was efficient
-: We only were able to sort 3 marbles
   Our funnel/hopper didn't work completely, had to adjust it
    We were unable to drop the marbles from 6 feet
?: Make a larger funnel
    Try to sort more marbles
    Use more fischertecniq products
!: Attempt to use the light sorters
   Make more of an upward facing hopper
   Add a more definite wood/metal marble sorter

Reference:
Our prototype was based off a trash sorter, shown here: reference


--------------------------------------Product Achievements------------------------------------------

Sorting Speed (15 marbles total: at least 3 different types):
Process 15 marbles in less than 2:00 minutes. 
Process 15 marbles in less than 1:45 minutes.
Process 15 marbles in less than 1:30 minutes.
Process 15 marbles in less than 1:15 minutes.
Process 15 marbles in less than 1:00 minute.
Process 15 marbles in less than 45 seconds.
Process 15 marbles in less than 30 seconds.

Marble Delivery (may use non-fischertechnik materials to create a "hopper" to drop marbles into for "Drop" achievements):
Drop marbles from 6" above machine 
Drop marbles from 1' above machine
Drop marbles from 2' above machine

Systems (not including motor or piston used to charge your pressure vessel):
Use at least one motor

Delivery vehicle control

We did the activity on 3.1.7 called delivery vehicle control, where we were to create a system that would transport goods between 2 point, based on an pentameter input. Eventually with some program tweaks, we were able to activate it.

Programming

We started probably the most basic form of programming this week. We started off with the robopro program on our computers, an interface, an a motor. We told it to start for 3 seconds, then stop. After that advanced to switches and a lamp. On Wednesday, we made the lamp go on, until it had been on for 8 seconds or more. This is a really cool topic.

Bridge Building Challenge PART 2

The overall goal of the past month and a half or so, was to better our original bridge design, which mine completely failed. So all of the moment calculations, truss calculations, MD solids, beam deflection, and Free body diagrams have been towards the overall goal of building a good, stable bridge.

2.1.7 Calculating trusses

We got more practice with trusses today during our block period. We used our 2J=M+R formula to determine if they were statically determinate, then solve for unknown values.

Truss Systems

A long and complicated process, truss systems are difficult to comprehend unless you know how to do it. It involves much of the information we have learned in the past, like moments, the use of free body diagrams, and trigonometry.
We had a large packet to complete, but I am only going to upload a few pieces of work:
As you can see, this work was very computational, and is very vague to anyone unfamiliar with the subject. All in all, I think this lesson will help u in our bridge building contest in the end of the lessons
