  • Design | Programming | Implementation

Eric Cauble - University of South Carolina Upstate - SCSC W314


Why diy robotics

WHY DIY ROBOTICS?

Arduino schematic

  • Learn concepts outside of CS

    • electrical engineering

    • computer engineering

PCB trace

DIY Arduino


Why diy robotics1

WHY DIY ROBOTICS?

  • Good for small-scale prototyping

  • Wealth of information resources:

    • online communities

    • open source code/ development environments

    • open source hardware


Why diy robotics2

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
