Foundational milestone
The Roomba 900 series provides
compelling user benefits today and is a
foundation for expanding the value of
robots in the home.
Key to this step is that Roomba is
connected and it systematically
navigates and maps the home.

16. © 2017, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
Since launch…
• 3 new models launched that can
connect to AWS
• System has been tested to support
millions of robots
• Over 25 million maps created!

Architecture Overview

Why cloud platforms and serverless?
• Reduce (but not eliminate!) operational overhead
• Developers are able to concentrate on business logic
• Scalability is “built-in”

Deployment of Cloud Based Software

24. © 2017, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
Deploying serverless code in AWS
• Needed something that could do the following:
• Build Lambda packages from function code
and common libraries
• Build API Gateway deployments
• Generate IAM roles for Lambda functions
• Need to support Red/Black deployments

iRobot cloud deployment tool
• Automates the deployment of our code
into an AWS account
• Uses CloudFormation custom resources
for unsupported services
• Auto-generates top-level stack with
cross-stack IAM roles and API
• Acts as a preprocessor for
CloudFormation Templates

Solution: Topic namespacing!
• Deployment tool can tag a deployment
with a specific ID and topic prefix
• Tool modifies IoT rules in
CloudFormation templates to
reflect ID
• Cloud also stores a mapping of robot to
deployment ID
• Robot can contact cloud to obtain
information about its assigned
deployment

Managing Lots of Things

33. © 2017, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
Managing lots of things
• In a deployed system, we need to know things about our robots
• How many are on version 2.2?
• How long was robot A’s last mission?
• Is Robot B currently connected to the cloud?
• IoT does not support queries on Thing Shadow values
• Needed to support various use cases within the business

34. © 2017, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
• Use Amazon Elasticsearch to store state of fleet!
• IoT rule listens on
$aws/things/+/shadow/update/documents
• Funnel updates through Amazon Kinesis/Lambda
so we can batch process events

Working with AWS

36. © 2017, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
Bring your own certificate
• Robots deployed in the field, not feasible
to load AWS-generated certificate
• Difficult to integrate AWS IoT certificate
process into manufacturing flow
• AWS reworked roadmap to support
BYOC before our launch

37. © 2017, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
Working with AWS enterprise support
• Weekly on-site office hours to help the
developers bring the product to market
• Worked closely to validate scalability
of system
• Bi-weekly cadence call with IoT team to
track enhancements to the service
• Scheduled load-test events to ensure
that service scaled well beyond our
current capacity

38. © 2017, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
In summary…
• Building on AWS has allowed us to
create a scalable system with a
small team
• Our Red/Black deployment scheme
allows us to move robots to different
versions of software with zero
downtime
• ElasticSearch allows us to perform
powerful queries on our fleet
of robots
• AWS has worked with us to help us
succeed on their platform
