  1. View slide notes for more info!!!!! DIY ROBOTICS • Design | Programming | Implementation Eric Cauble - University of South Carolina Upstate - SCSC W314

  2. WHY DIY ROBOTICS? Arduino schematic • Learn concepts outside of CS • electrical engineering • computer engineering PCB trace DIY Arduino

  3. WHY DIY ROBOTICS? • Good for small-scale prototyping • Wealth of information resources: • online communities • open source code/ development environments • open source hardware

  4. WHY DIY ROBOTICS? • Cheap, readily available parts

  5. Single-board microcontrollers • Arduino (C++) $20- $70 • IOIO (Android) $50 • FEZ Panda (.NET/C#) $40 • Raspberry Pi (Python) $25

  6. HARDWARE - MOTORS Servo $15-$25 DC Motor $2-$10 Stepper $15-$25 Linear actuator $80-$150

  7. HARDWARE - COMPONENTS GPS Module $75 Gripper $10 Accelerometer $30 Arm link $30 Gyro module $30

  8. 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

  10. 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
