Team Members Soldiers of Technology 2435B

Hope Chambers Team Position: Team Captain, Builder and Programmer School and Grade: Homeschooled 10 th Grade Skills: Programming, Building, and Notebook Hobbies: Playing Violin and Piano and going hiking. Favorite Subject: Any kind of math College Goals: Massachusetts Institute of Technology (MIT) Why did you join robotics? I joined because I am interested in a career in robotics and wanted to get a little taste of the field before I went to school for it. This is my second year and I defiantly know that robotics would be my dream job. Soldiers of Technology 2435B

Jordan Johnson Team Position: Builder and Driver School and Grade: Lawton Christian School 11 th Grade Skills: Driving, Experience, Notebook and Physics Hobbies: Singing, Reading, and Playing Video Games Favorite Subject: Mathematics and Science College Goals: Baylor University Why did you join robotics? I love engineering and felt this would help me be prepared for my future careers. I also think it will be fun. Soldiers of Technology 2435B

Andrew Gonzales Team Position: Builder and Portfolio School and Grade: Homeschooled 11th Skills: Building, Notebook, and Portfolio Hobbies: Boy Scouts, Studying, and Internet Surfing Favorite Subject: Math and English College Goals: Oklahoma State University Why did you join robotics? I’m looking forward to begin in engineering and robotics will provide many opportunities for preparation. Soldiers of Technology 2435B

Phillip Shell Team Position: Builder and Driver School and Grade: Lawton High School 11th Skills: Driving, Experience, Building, and Notebook Hobbies: Hanging Out with Friends, Video Games, Reading and Robotics Favorite Subject: Science and History College Goals: Massachusetts Institute of Technology(MIT) or Oklahoma State University Why did you join robotics? I thought Robotics could let me think and collaborate with other people. Soldiers of Technology 2435B

Design Process Step 1 1 Define Problem Step 6 Step 2 Present Generate Solution Concepts Step 5 Step 3 Evaluate Develop a Solution Solution Step 4 Construct And Test Prototype Soldiers of Technology 2435B

Define Problem • Watched VEX Starstruck Game Video • Studied the VEX Starstruck Rule Book • Discussed Design Specifications • Evaluated Defensive and Offensive Scoring Options • Discussed Team Positions • Created Design Brief, Gantt Chart, and Team Norms Soldiers of Technology 2435B

Define Problem Design Brief Client: Instructor(Trecia Karinshak) Target Consumer: VEX Robotics Team 2435B Designer: VEX Robotics Team 2435B Problem Statement: We were challenged to design a robot that can effectively launch stars and cubes to the enemy alliance side efficiently and hang on the hanging bar Design Statement: After brainstorming for the best solution, we would build and test the robot to make sure it met are design specifications Criteria and Constraints: Our robot had to fit within the 18’’ by 18’’ by 18’’ dimensions, was limited to only 12 motors, could only use VEX certified parts, and had a time constraint of two months Conclusion: We decided to go for a Dump Truck/Launcher which sends/throws stars and cubes over the fence Soldiers of Technology 2435B

Design Process Step 1 Define Problem Step 6 Step 2 2 Present Genera rate Solution Concepts Step 5 Step 3 Evaluate Develop a Solution Solution Step 4 Construct And Test Prototype Soldiers of Technology 2435B

Generate Concepts • Individually brainstormed robot designs and subsystems and collectively chose a final design • Brainstormed criteria for ideal robot attributes and characteristics • Created and implemented a Decision Matrix which helped determine a solution path Soldiers of Technology 2435B

Construct and Test Prototype • Constructed three chassis and decided with the overall best chassis • Created two subsystems and later redesigned first subsystem • Collected and Analyzed information and data from competitions to redesign our robot Soldiers of Technology 2435B

Construct and Test Prototype Chassis 1 Chassis 1 was our first P prototype chassis. This chassis was completely made out of steel and had a high speed gear train with high speed motors. We used this to practice driving and later on transformed it into a push bot. Soldiers of Technology 2435B

Construct and Test Prototype Chassis 2 Chassis 2 was our second and current chassis. This chassis held the pitchfork subsystem before we replaced the claw subsystem. It has a torque gear train with turbo motors to provide the perfect combination of both speed and power. Soldiers of Technology 2435B

Construct and Test Prototype Chassis 3 and Launching Mechanism Robot Chassis 3 was our third chassis and would hold 1. 2. our Choo-Choo 3. Launching Mechanism 4. subsystem. This chassis 5. was not use by the fact 6. that is could not rotate 7. properly. Soldiers of Technology 2435B

Construct and Test Prototype Dump Truck with Pitchfork This was the first fully designed robot we had made by the combination of Chassis 1 and our Pitchfork subsystem. However, we later changed this for a different subsystem that would allow us to do much more. Soldiers of Technology 2435B

Construct and Test Prototype Dump Truck with Claw This was our chassis 2 combined with our current Claw subsystem. This new subsystem allowed us to transport multiple stars and cubes across the field now. Soldiers of Technology 2435B
