VEX Robotics Curriculum

During the summer of 2018 we will be using the VEX Curriculum to model a summer mechanical engineering class.

To access the curriculum, visit https://curriculum.vexrobotics.com/home.html

 

Notes on the class can be found below.

Class #1:
July 9, 2018

  • The Engineering Design Process
    • Problem Statement
    • Brainstorming
    • Mockups and Prototypes
    • Testing
    • Did it work? If not, try again!
  • Intro to Engineering
    • Team dynamics
    • Write everything down!
      • This provides proof for later
    • Challenge ideas
    • Ranking system for engineers
      • W- Wish, not important but would be nice to include in machine
      • P- Prefer, important but would still work without it
      • D- Demand, must be included
    • Problem statements need to be clearly defined
      • Describe the action desired, not the potential machine
    • Design documentation
      • Troubleshooting, proof, info
      • Include failures and successes- this shows the results good and bad
  • Intro to Robotics
    • What is a robot?
      • Something that can be manufactured to do a job
    • Components:
      1. Body/frame
      2. Control system
      3. Manipulators
      4. Drive train
  • Speed, Power, Torque, and DC Motors
    • Classical mechanics
      • Speed- how fast, motion over time
      • Rotational speed- angular speed, angular distance over time
      • Acceleration- change in speed over time, rate of change of speed.
      • Force- accelerations cause forces which cause change in movement, direction, or shape
      • Torque- force directed in a circle
    • DC motors
      • Motor loading- motor can only apply torque in response to loading
        • The more torque, the slower the rotational speed
      • Current draw- load effects the current
        • More current means more power/speed
