get started
GET STARTED
  • Create a goal, or task you want your robot to complete
  • Design your robot/buy parts based on your goals
  • Assemble it from your parts list
  • Program one step at a time
  • Test and improve

questions
Questions
  • Q: Why would a brushed DC motor be a poor choice for an arm joint motor?
        • A: Hard to measure rotations, speed controlled by applying resistance, need to physically swap positive and negative leads to reverse rotation. http://electronics.howstuffworks.com/motor2.htm
  • Q: What are the main differences between a servo motor and a stepper motor?
        • A: Servos use encoders to provide position, speed and feedback. Standard servos can only turn between 0 to 180 degrees.
        • A: Steppers divide a full rotation into a number of equal steps. Use electromagnets around iron gear to turn motor. Steppers can make full rotations.
  • Q: Name one Single-board microcontroller.
        • A: Arduino, IOIO, FEZ Panda, Raspberry PI, Make Controller, PIC Programmer, DWENGO, AVR
