Cereal Pamphlet Project

Names: Aidan Sochowski, Dru Tibbetts, Anthony Valiaveedu, Mykyta Solonko     

     For this project we measured the amount of iron in a couple of breakfast cereal. We later researched the need of iron in the body and how much the person needs. We also looked up the problems that can occur if too much iron is consumed. Below is our project. For some reason, the same image is shown four times instead of one.

Golf Ball Challenge Lego Mindstorms


   For this challenge in PLTW, a mindstorm robot had to pick up a ball, drive it under a ramp, and put it into a box. The ramp is slanted with the lowest part closer to the box. It is to our advantage to make the robot as short as possible so that it does not have to drive for a long time alongside the ramp. We were allowed to use 3 motors. We used 2 for the wheels and one for the claw(to pick up the ball). Our robot is easily able to fit under the middle of the ramp.

Below is the greatest run EVER!

Below is one of our failed runs...(It is hard to see, the ball did not roll into the box)

Arduino Obstacle Avoiding Robot

Recently, I have made an obstacle avoiding arduino robot. This robot drives around the floor and doesn't crash into walls. I used an HC-SR04 ultrasonic sensor for this robot in order to detect the distance from the nearest object. I also used 2 6-volt continuous servo motors in order to move the robot forward. I used an Arduino, breadboard, and some wires. I used a 9 volt battery to power the arduino and a 4 AAA battery pack to power the motors. I made the chassis out of cardboard and made the front wheel from two mineral water caps. I 3d modeled and printed a part to hold the wheel in the front. For science, I had to build circuits. For technology, I had to utilize an arduino, program it, and use the 3D printer. For Engineering, I had to construct the chassis and 3D model the part in Autodesk Inventor. For math, I had to calculate the dimensions of the cardboard chassis and for the 3d modeling. I also had to find the conversion formula to connect the width of the returning ultrasonic signal to distance in cm and inches.

Puzzle Cube Reflection

During this project, I glued wooden pieces together to form a 2.25x2.25 inch puzzle cube. The cube has 5 unique pieces that fit together. The total amount of small cubes used was 27. I later used a laser engraver to engrave inspirational quotes on the puzzle cube for each of the six sides. I used autodesk inventor to model each part and then I put the together. I made a document set with each part dimensioned. I collected results from people and observed that STEM students to better on this puzzle cube. A graph can be seen below. 

Graph of average results on the puzzle cube



The separate time of each individual can be found below.



I made a video about me finding parts of the cube and putting them together. It can be found below. 



Below, you can find more pictures of myself in progress of building my project.
