1. Internet of Things (Part 1)
ROBOMO
Craig Walters 8/5/2017

2. IOT is About Making Devices Talk to Each Other
Will be intrinsic to our life in 10 years
About ½ way between a Machine and a Robot
Share information about what a device is doing
“Headless” – No UI
Network-connectivity
Typically with at least 1 wireless leg
Internet is typically involved

3. The Collection Model Uses an IoT Gateway
Data sent to/from embedded device to a central server
Home appliances
Health monitoring
Cars
Closely related to “Big Data”
Amazon Web Services, Azure, Oracle have SDKs
Cell Phones
Uses an IoT Gateway
NOTE: Generational differences on acceptance

4. The Interaction Model
Data sent between embedded devices to coordinate activities
Self-driving cars
Cars (Vehicle to Vehicle – V2V)
Over 50 processors in a typical 2017 model
The NTSA proposed a rule (Dec 2016) that would require automakers to include V2V technologies in all new light-duty vehicles. The rule proposes requiring V2V devices to “speak the same language” through standardized messaging developed with industry.
SmartHome
Uses an IoT Gateway
Drones (
Robots ( (

5. Starts with a “Thing” Has Features Has computational intelligence
Computation is not its primary purpose
Has valuable information to share
Connectivity
(Maybe) Can benefit from information other “Things” have
Special Purpose Device

6. Use Off-the-Shelf Components
Applications written in different languages
HTTP or HTTPS and ReST or SOAP
MQTT and Kura
Publish Subscribe model
ROS
CoAP (Constrained Application Protocol) and Californium
HTTP over UDP
Some Critical Components
Sensors
RFID/Bar Codes (old-school RFID)
JSON
Often based on Web Servers or derivatives
Works like a Web Page
Closely related to Service Oriented Architecture (SOA)

7. HTTP(S) & MQTT Dominate

8. The IOT Robotics Architecture
Be Careful about overloading the Arduino with messages from the Pi
Controls the sensors and devices
IoT Gateway
Wireless connection
Could control devices too

9. How does a Browser Get a Web Page?

10. What a Network Looks Like

11. Open Source APIs Eclipse IOT API (https://iot.eclipse.org/java/)
Spring Boot (
Requires Java 1.8
Microservices
Pi4J (
RoS

12. CoAP with Californium

13. Example with MQTT and Kura

14. Installing Kura on Raspberry Pi
