The VEX EDR Curriculum is designed to help students in grades 7-12 explore the fundamentals of robotics and the engineering design process while learning to use industry-leading CAD software, and VEX Classroom Robotics Kits. Students will walk through the design and build a robot to play a sport-like game, while also learning key STEM principles, and robotics concepts. At the culmination of the class, they compete head-to-head against their peers in the classroom, or on the world stage in the VEX Robotics Competition.

Curriculum:

  • Strategic Analysis
    • How to evaluate the difficulty of a tasksuper-kit-clawbot
      • Weighted Objective Tables
    • Determining how a game will flow
    • Determining how a game will evolve through the course of a season
    • Determining the Strategy that will maximize score within one’s own capability
  • Design Process, detailed
    • Define the Problem
    • Background Research
    • Specify the requirement of the design (weight, size, task, design constraints etc.)
    • Brainstorm, Evaluate and Choose a Solution

    • Radio-Release Mechanisms
      • CAMS
    • Driven Intakes
    • Elasticity
      • Damping Co-efficent
  • Software (Robot C or Robot Mesh)
    • Robot Mesh Studio is a drag and drop based language for beginners
    • Robot C is a industry used robotics language, allowing everything from PID to motion profiling
    • Autonomous Control
    • Sensors
      • Gyro
      • Encoders
      • Color Sensor
      • Bumper Switch
    • Writing PID Control
    • Code Iteration Process

 

In order to enforce the learning and make learning more interesting and engaging, designed games will be applied in all classroom sessions:

  • Place stress balls over the wall for 1 point
  • Place stress ball in goal for 3 points
  • Place foot ball over the wall for 3 points
  • Place foot ball on shelf for 5 points
  • Match is 2 minutes long, with 2 drivers. 1 person will drive the robot for 1 minute before handing off to partner
  • 10 second autonomous period, anything scored in this time will be doubled in points
  • *Note that this game is designed to work with the instruction clawbot

 

The game and field is that same as for Vex EDR Swept away, except for different point values and an added shelf made out of either a box or wood
