2. WHY DIY ROBOTICS? Learn concepts outside of CS electrical engineering computer engineering Arduino schematic 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 Linear actuator $80-$150 Stepper $15-$25

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

8. GET STARTED 1. Create a goal, or task you want your robot to complete 2. Design your robot/buy parts based on your goals 3. Assemble it from your parts list 4. Program one step at a time 5. Test and improve

10. Questions Q: Why would a brushed DC motor be a poor choice for an arm joint motor? 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 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 http://electronics.howstuffworks.com/motor2.htm Q: What are the main differences between a servo motor and a stepper motor? 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: 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. 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. Q: Name one Single-board microcontroller.
