A Little Bit About Projects

              As a group we all viewed videos of previous competitions and different designs of robots in order to better visualize some of the conflicts that come up during a competition. We also built cardboard prototypes to better understand the actual size of the robot and what it was going to look like. We had a group member of the club give a short presentation on programming and tell us a little bit how it works. In Vex and any other type of designing or engineering it is vital to plan and map out what you want to do and the best strategy to accomplish the task. 

           Our workplace is in L.C.B. High School’s engineering wing. We work in room SC13, Mr. Wagner’s freshman engineering room. 

Planning


             Our instructors require us to always make initial plans and brainstorm about our ideas. Our team separated and gathered our idea into one proposal of what we thought would make our robot more efficient. We debated on the pros and cons of using several different designs that we had previously viewed on a videos in the first few days of the club. We talked about different aspects of a robot like torque, the center of gravity, structural systems, motion, power, and pivot. Eventually we came to an agreement on one idea. 

Robot


           As of right now this is our robot. We chose to use an extending and retracting arm on both sides, we are also going to attach a claw onto the end to grasp the game pieces. Since this is just the preliminary building of or robot we have not actually tested the efficiency of it. The center of gravity maybe of some concern because if the average position of all the mass on the robot is slightly off we are going to have a lot of difficulty during competition. Other than that aspect of the robot we chose to use a U-shaped chassis since we want to have a robot that sort of corrals the game pieces into the claws of the robot.  Also we used the 4” Omni wheel in the front in order to provide the robot with better mobility, and normal 4” wheels in the back similar to the set-up of a regular real life vehicle

Intro

In the engineering program at L.C.B. High School high school juniors are required to participate in a year  long engineering competition. We are divided into four large groups and our instructor Mrs. Hoover holds a seminar about the different projects we are assigned every nine weeks. Vex Robotics, which is the engineering competition I chose, is a high school club. In Vex we apply engineering and robotics in order to learn about the design , construction, and operations on electronics.  Robots are machines that can operate autonomously or in this case by programming and control systems.
