1. The Ubiquity Robotics Platform
Using Open Source Software for Domestic Robot
Research and Development

HBRC
What would you do with your own personal robot?
Ubiquity Robotics
2. Why?
A widely available affordable, adaptable and
capable developers platform would bring about
a new age of personal/domestic robots.
Ubiquity Robotics
About thirty years ago, ‘personal’ computers became affordable. We’ve been
waiting patiently for the advent of ‘personal’ robots. We are done waiting.
3. You can’t buy a general purpose personal robot today.
Developer Platforms
or single purpose.
1.5k 40k 400k
Ubiquity Robotics
4. We want Rosie or R2D2...
Ubiquity Robotics
..but we have Roomba or Turtlebot. Neither are very
capable. What we need now is a developers platform
that is both adaptable and capable.
5. Hardware is difficult.
Software is even more of a challenge.
Fortunately, Willow Garage developed software called
ROS – Robot Operating System
Ubiquity Robotics
The Dilemma:
6. What is ROS?
Ubiquity Robotics
•A Distributed, Modular Design
•A Vibrant Community
•Permissive Licensing
•A Collaborative Environment
Open source Linux based, recent Indigo version
tuned for Ubuntu 14.04, module update via apt-
get. Catkin build system for adding custom code
in Python, C+, Java. Works on ARM (BBB, Jetson,
Android, Raspberry Pi 2.
7. ROS is an “OS”
Ubiquity Robotics
What does that mean? As there was no ‘Google’
until there was a browser and an http server –
widespread use of autonomous robots require an
OS infrastructure. For personal computers we
had CP/M, and then MS-DOS.
ROS has a steep learning curve, but the work
load for developers is reduced considerably, and
the complexity is transparent to the end user.
8. ROS Standard Robot Messages
Ubiquity Robotics
•Standard Message Definitions for Robots
•Robot Geometry Library
•Robot Description Language
•Preemptable Remote Procedure Calls
•Diagnostics
•Pose Estimation
•Localization
•Mapping
•Navigation
11. ROS – 1000s of users, but few entry level platforms.
• Southwest Research Institute (SwRI)
• Skybotix
• Aldebaran’s NAO humanoid
• Meka Robotics' systems
• Murata
Why launch now?

14. How?
• Open source software (ROS)
• Advanced COTS technology
• Agile methodology (Trello, Slack, Github)
• Product designed around the existing
supply chain, not vice versa.
Ubiquity Robotics
15. What?
‘Magni*’ Robotics Platform
• 100 lb payload
• 8 hours endurance
• navigate in ADA compliant space
• widely adaptable for useful work
• affordable
*Magni was originally called Hercules.
Ubiquity Robotics
16. Hercules* V-1 was based on
an electric wheel chair and
weighed about 150lbs. The
motors weighed 20lbs each
and needed 2 automobile
lead acid batteries.

17. Ubiquity Robotics
• Brushless hub
motors
• Custom ESC
• Tubular steel chassis
• Rear Casters
• SLA Batteries
• ARM based CPU
• COTS sensors
Ubiquity Robotics
21. Marketing – Roll out plans.
First 10 Magni platforms are under construction. After
video production, we plan to go forward with a
crowd funding campaign raise enough capital to
manufacture 300 to 1000 units.
Ubiquity Robotics
22. Like the personal computer, we really do not know
what the best purpose for our platform will be. We
have a few ‘use cases’ we can demonstrate. It is up to
you to develop the ‘killer app.’

27. Introducing: Loki
Ubiquity Robotics
Loki is a small robot used to learn ROS (Robot Operating
System.) ROS runs on a Raspberry Pi 2 computer board and
plugs into the Loki, controling 2 motors with drive electronics
and wheel encoders, 16 sonars, a 5 mega pixel camera, a 4
degree of freedom Arm, and a 6000mAH battery. An USB
wireless dongle is used to download software developed on a
laptop/desktop system, or run the robot via teleop.
