Android based robots - Updated - EED Session - Sept 2013
- 1. Android-Based Robots Bridging the gap... Khaled Al-Kady Robotics25
- 2. Key points ● Why Android-based robots are important? ● How to build an Android-based robot?
- 3. Message to engineering students ● Software development frameworks and techniques evolved – Make use of today's technologies – Don't live only in the limited resources world ● Choose your battles, delegate some work to Android
- 4. Message to computer science students ● Entering the robotics field is easy, the old barriers no longer exist ● Expand your knowledge, know more about hardware and leave your comfort zone
- 6. What is special about Android-based robots? ● Easier integration – Built-in I/O devices ● Better development environment – Huge memory, fast processor – Lots of utilities – Java
- 7. input devices output devices Micro-controller IOIO or Arduino Android device How it works – physical connections
- 8. IOIO capabilities ● Microcontroller with 48 I/O pins ● Controlled by Android or PC applications ● Supports many device types – DigitalInput : Button, ... – AnalogInput : Potentiometer, Ultrasonic sensor, ... – PulseInput : RC receiver, Mouse wheel, ... – DigitalOutput : Led, Stepper motor, ... – PwmOutput : Servo, Brushless motor, ... ● Communication: UART, I2C, SPI
- 9. Code!
- 10. ● Demo 1: Potentiometer controls a servo motor ● Demo 2: Built-in accelerometer controls a servo motor ● Demo 3: CNC plotter Demo
