Machines for Risky Intervention
• Autonomous and human supervised autonomous robots for risky intervention require intelligent capabilities executed by machines in a timely fashion.
• Machine intelligence may be achieved by the interaction of control agents acting in a dynamic environment.
• Let’s consider an example: Neutralization of an Improvised Explosive Device (IED).
January 8, 2008Spark Robotics RISE08
Example: Neutralization of a CBRN-E device.
• The scenario of a terror attack using an IED is today a major concern in Europe and in the rest of the world. – In the near future it may contain Chemical, Biological,
Radiological or Nuclear (CBRN-E ) agents– It is also reasonable to be used as a tool for threat
and as such may be found before its activation.
January 8, 2008Spark Robotics RISE08
The Problem• Unknown structure and design
– As an improvised device presents the human operator team with unknown and unexpected situations.
– Needs more accurate technical treatment than neutralization of usual explosive devices in order to reduce to zero the possibilities of human error.
• A lot of general information is available– large variety of information data bases for situation
analysis – integration of a large variety of tools for sensing or
acting
January 8, 2008Spark Robotics RISE08
The Problem• The neutralizing device should be assembled and integrated from
several systems.• Connection to device information databases over the Internet. • Sensors and actuators required to perform the task should be
handy. However,– before the incident occurs, only some of the sensors to be used
for analysis, can be allocated.– while actuators and sensors to be used during the
neutralization phase can be allocated only after the analysis phase is completed.
– The operating system has to be built on the spot and under the constraints of a crisis situation, in a timely fashion and with extremely high quality assurance.
• This is of course a very demanding task.
January 8, 2008Spark Robotics RISE08
The neutralization robot• Is developed beforehand, but its functionality has to be
flexible enough to be adapted to very different situations. • From some aspects it should be possible to reintegrate
its components according to the specific scenario.

The Intelligent Command, Communication and Control System • The responsibility to control and monitor
the Global Goal in a very professional and reliable manner.
• Will perform under a Human Autonomous Supervisory Control regime.
• Will include numerous agents and modules– reliably communicate and exchange
information. • Enforce
– a reliable fault tolerant system– trustable communication – messaging server – process manager to ensure system
safety– System Builder tool to integrate the
sub-systems

Introducing DISTRIBUTED INTELLIGENT OPERATING SCHEMA: DIOSTM
• The machine has to be capable to integrate into a working system several different and frequently new sensors or actuators – as the existing ones may be replaced by a new
product or an updated version of the same product. – Assembling a system to be able to deal with complex
situations requires integration of very different subsystems.
• An Operating Schema to serve as a tool to make that task doable under the stressed situation of a crisis is not a luxury, but a necessity.

DIOSTM VISION STATEMENT
To be the widely accepted tool for development of distributed systems, using application agents for information exchange in robotic control systems
and intelligent devices.
To enable the creation of a new generation of better connected, more intelligent, cost effective, reliable and of on the spot assembled robotic vehicles.
January 8, 2008Spark Robotics RISE08
How DIOSTM works• Hide the details of the specification from the particular application.• Does not tie an application to a specific type of hardware.• Allow Agents to be created in multiple programming languages
C for microcontrollers used in Hardware Interface Modules (HIM),
C++, Python, and Java (more in the future)• Automatically generates code to standardize communication and prevent dependency issues between Agents
SPEED UP DEVELOPMENT

DISTRIBUTED INTELLIGENT
OPERATING SCHEMA
• Specifies what information can be broadcast/ listened to.
• Does not distinguish between “real world” components (sensors, actuators) and “virtual components” in software (behaviors, decisions).
• Real-time requirement for guaranteed message delivery
SPECIFICATION
January 8, 2008Spark Robotics RISE08
• Software medium through which all Agents communicate with each other.
• Invisible to the application developer and end user.
• Fully distributed – ability to create applications with no single point of failure.
• Commercial robotics framework developed for the QNX Real-Time OS.
FRAMEWORKDISTRIBUTED INTELLIGENT
OPERATING SCHEMA
January 8, 2008Spark Robotics RISE08
• Units of FUNCTIONALITY• Perform on behalf of a supervisory unit (agent or
human operator)• Are
– Autonomous– Situated (in the environment)– Reactive– Pro-active (make decisions to achieve goals)

The System Builder
• The purpose is to simplify and automate the task of – defining, – creating, – maintaining, and – arranging Agents for use in a DIOS-enabled system.
• Acts as a repository for all DIOS-enabled software and the management thereof.
• Projects are comprised of many Agents using shared Models.

DIOS™ System BuilderAllows the developer to use whatever
specification it choose.
Works on:
January 8, 2008Spark Robotics RISE08
Agent definition screen of the SystemBuilder running under OSX 10.4 Tiger.
• The System Builder requires that the user specify the information that an Agent requires in order to function and complete its task.
• By defining an Agent with the above properties, the System Builder then auto-generates all of the code required for communication along with the programming stub for the Agent.

• The hierarchal organization of software objects composed of data-type fields are defined in the "Information Model".This is necessary to let System Builder connect parts according to their hierarchy.

Using the SystemBuilderSteps:1. define agents2. define information models3. associate information
models with Agents4. Generate code (in C++)
for the keyboard driver5. Use the keyboard driver to
control a simulated robot6. Show the auto generated
Java keyboard driver code
7. Show the simulated robot controlled by the java driver
