Slide 1: Welcome
Slide 2: CLOUD ROBOTICS WITH ROS ( ROBOTIC OPERATING SYSTEM ) Titto Thomas Roll No.47 S7 A College of Engineering, Chengannur
Slide 3: Robotics   Robots - mechanical intelligent agent which can perform tasks on its own, or with guidance They can be industrial, mobile, service , humanoids..etc Touches every instant of life in one way or the other Robotics - deals with design, construction, operation, structural disposition, manufacture and application of robots Dynamically growing industry and its in need of alternative and new ways 1    College of Engineering Chengannur
Slide 4: Where do we stand ?  Require great computational capabilities to be able to process – in real time – images, faces, voice, sounds, obstacles many more Necessary to have a very powerful – and high energy consuming – processor and peripherals on board. Necessary to carry huge and heavy batteries as well 2   College of Engineering Chengannur
Slide 5: ROS (Robotic Operating System )  Software framework for robot software development developed in 2007 under the name switchyard by the Stanford Artificial Intelligence Laboratory in support of the STAIR Based on graph architecture & is geared toward a Unix-like system    Doesn't have to ”reinvent the wheel ” College of Engineering Chengannur 3
Slide 6: ROS is..  Peer-to-peer Multi-lingual Tools-based Thin Free and OpenSource       Exponentially growing Used in many applications including Willow Garage’s PR2, Aldebaran’s Nao and Shadow’s robotic hand 4 College of Engineering Chengannur
Slide 7: Cloud Computing  Using multiple server computers via a digital network, as though they were one computer the services available are considered part of cloud 5  College of Engineering Chengannur
Slide 8: Cloud Provides..  Device and location independence Significant workload shift from the local computers Cost is reduced as capital expenditure is converted to operational expenditure    Sharing of resources and costs across a large pool of users Highly reliability and efficiency   Improved security due to centralization of data Easiness in supporting and improving a software Scalable - dynamic provisioning of resources 7   College of Engineering Chengannur
Slide 9: ROS in the Cloud College of Engineering Chengannur 7
Slide 10: High Level Overview Computer jobs & sensor data Server Cluster Cloud Computing Framework Ros Messages ROS Messages over http Private Cloud (Intranet) Public Cloud (Internet) ROS Messages over http ROS Framework 8 College of Engineering Chengannur
Slide 11: Architechture In Layers Storage / Compute Nodes Distributed File System and necessary services Cloud Framework Master & Subscriber Nodes ROS Nodes College of Engineering Chengannur 9
Slide 12: ROS Messaging Example Publication Topic Subscription Node Node Service Invocation College of Engineering Chengannur 10
Slide 13: Cloud Enabled Robots Can.. Understand Perceive Share & REACT College of Engineering Chengannur 11
Slide 14: Why should we ??  Off the shelf hardware means affordable robots Lower the barrier to entry for robotics Scalable CPU, memory, and storage shared knowledge database hardware upgrades are invisible & hassle-free Longer battery life 12      College of Engineering Chengannur
Slide 15:  lighter, easier-tomaintain hardware (akin to desktop PC vs. a thinclient “netbook”) Robot experiences / history / behavior outcomes / learned skills can all be published or data mined Expanding the knowledge beyond “Physical Body”   Cheaper , Lighter & Smarter College of Engineering Chengannur 13
Slide 16: Needs Improvisation  Cloud Computing is still taking baby steps, so will have to wait for the platforms to develop cloud-based applications can get slow or simply become unavailable leaving the robot “Brainless”   Tasks that involve real-time execution require onboard processing College of Engineering Chengannur 14
Slide 17: Implementations till now.. ● RoboEarth - to develop a “World Wide Web for robots” ASORO’s Cloud Computing Infrastructure Google’s initiative with Android Nao Humanoid Robots Google’s street View Robot DAviCi framework Project Phondox Turtlebot from google ● ● ● ● ● ● ● College of Engineering Chengannur 15
