● Knowing how to enter the field

3. Today's Message

● Knowing how to enter the field

4. Easy!

5. What is a Robot anyway?
Input Processing Output
Taken from environment not from Usually includes making a
keyboard! physical action
Position (Gyro, Accelerometer) Rotating a motor
Distance (Ultrasonic sensor) Making a sound

6. What prevents software developers
from building Robots?

7. Problem 1: IO
Interfacing with external devices
You can't debug wires!

8. Solution for problem 1: IO
Interfacing with external devices – still exists,
but no longer includes:

9. Problem 2: Processing
Basic micro-controllers
● Low level programming
● Physical constraints
● Lack of utilities

10. Solution for Problem 2: Processing
● Advanced Micro-controllers
– Arduino
● Computer on chip
– RaspberryPI
– BeagleBone
– PcDuino
● Phone + Advanced Micro-controller
– Android + Arduino
– Android + IOIO

11. Demo
● Demo 1
– Remote controlled plane
● Demo 2
– The plane controls itself

12. Demo: Architecture
Phone + Advanced Micro-controller

13. Demo: Components
IOIO Android Phone
Remotely controlled Android 1.5+
micro-controller (USB &
Bluetooth)
48 Input/Output pins

14. Demo: Components
Servo Brushless Motor
class PwmOutput class PwmOutput
+ setPulseWidth() + setPulseWidth()
Values: 500-2500 Values: 1000-2000

15. Demo: Components
Ultrasonic sensor Built-in Accelerometer
class AnalogInput SensorEventListener
+ getVoltage() + onSensorChanged()
Values: 10mV/inch Values: -9.8 to +9.8

16. Demo: Code!
IOIOActivity BaseIOIOLooper IOIO
createIOIOLooper() setup() openPwmOutput()
loop() openAnalogInput()
MyScreen MyLooper InputWrapper
createIOIOLooper() setup(){}
{
loop(){}
} OutputWrapper

17. Other approaches 1/2
Phone + Micro-controller
● Android + Arduino
– ADB: Android Debug Bridge
– ADK: Accessory Development Toolkit
– SPP/Bluetooth: Serial Port Profile

19. Where to find components?
Hacks
● DVD writers
– Bushless motor + Stepper motor + Laser !!
● Old toys & Mechano
● Car window motor, windscreen wipers
RC shops
● HobbyKing.com
● Electronics shops in city center
