The Ubiquity Robotics Platform
Using Open Source Software for Domestic Robot Research and Development
Presented by: Alan Federman, et al.for
HBRC
What would you do with your own personal robot?
Ubiquity Robotics
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.
You can’t buy a general purpose personal robot today.
Developer Platforms or single purpose.
1.5k 40k 400k
Ubiquity Robotics
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.
Hardware is difficult.Software is even more of a challenge.Fortunately, Willow Garage developed
software called ROS – Robot Operating System
Ubiquity Robotics
The Dilemma:
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.
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.
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
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?

LowLow
•Low cost general purpose machine possible when both high cost general purpose and low cost specific purpose machines exist
•Home brew enthusiasts first to enter with difficult to manufacture designs
•Opportunity exists for low cost general purpose mass producible design

High
LowLow
•Current situation indicates low cost high flexibility robot possible
•Need to create easy to manufacture design
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
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
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.

*Magni
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
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.’

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.
