Here is another vex lab from PoE. This project is a cookie topper, which is supposed to take "cookie dough" and add some toppings to them - "chocolate chips". Our machine is very ambitious but worked at the end. the machine used a conveyor belt with standoffs to take in the "cookies", which were simulated by wheels, then a sprocket connected to a servo motor spins, dispensing the "chocolate chips", which are tiny standoffs. The process continues and the cookies fall off of the conveyor belt into a holding area. the machine starts when a bump switch is pressed, and red and green LEDs indicate the status. When the red LED is on, then the machine is in motion, when the machine is not, then the green led turn on.

It is the beginning of Semester 2 in school and we finally started doing robotics in POE. I was excited because I loved robotics, electronics, micro controllers, and coding. We built a "TestBed", which was a plate with a VEX cortex brain, connected to servos, motors, and sensors which was designed to teach us about the basic and advanced VEX robotics coding. I really enjoyed the lab and i earned a lot of coding skills. In this post, you will find pictures of my lab and a video that shows you some of the cool things that I learned and some of the things that I can do with the TestBed. This is another vehicle lab we did, except with the fact we cant use ramps/ catapults. we built upon our successful design last time with a heavier counterweight, a higher IMA, and bigger wheels. The counterweight now slides on fixed sliders rather than it dangling on a string, this created a more stable design.
This year, i participated in the bridge design contest 2015 that is hosed by Engineering encounters. I Finished building my bridge which came in at a cost of $181,342.92, And that was the lowest i could get it. As of now i am 14th in my school. Here is a screenshot of the design: Here is the link to the latest standings: http://judge.bridgecontest.org/standings/local/LJOY Here is the project file (Only usable with bridge designer 2015): ![]()
Another compound machine lab, but this was a fun one... I am really happy with my results of this lab. Find attached to this post the video of this lab and some pictures. Today, We did a lab on simple machines. We learnt about All types of levers, wheel and axles, pulleys. It was fun building with the VEX EXR kits and calculation the IMAs.These Are Some Pictures of the Crane/Tank that I made for my POE compound machine lab 1. it has a giant crank which lifts the arm through the use of rope and a pulley transfer system. my machine has an overall IMA of 20.586. You can find a scan of my lab sheet attached to this post. 10/21/2015 PLTW Principles OF Engineering - Back To The Future - Sketching And EDP Exercise.Read Now
