85_0
OpenRTM-aist is a software platform developed on the basis of the RT middleware standard.
85_1
OpenRTM-aist is developed by National Institute of Advanced Industrial Science and Technology which
85_2
also contributes to definition of the RT-middleware standard.
85_3
Abstract
85_4
In RT middleware, all robotic technological elements, such as actuators and sensors, are regarded
85_5
as RT-components (RTC). Each RTC provides ports to communicate with other RTCs, and developers can
85_6
implement their own robotics technology (RT) systems as RTCs. The RT-middleware can thus be
85_7
considered as a distributed control architecture.
85_8
RT-middleware is originally a platform independent model (PIM). Implementations of this model
85_9
include CORBA, Enterprise JavaBean (EJB), and .NET Framework. OpenRTM-aist is based on the CORBA
85_10
technology and implements the extended RTC specification. Experiences with OpenRTM-aist will be fed
85_11
back to the RT-middleware standardization process.
85_12
Characteristics
85_13
OpenRTM-aist implements some extended RTC features, and it also includes a Manager component to
85_14
help manipulating RTCs. RTCs in OpenRTM-aist can be implemented using many programming languages,
85_15
and RTCs programmed in different languages can communicate with each other. A lot of tools to ease
85_16
RTC manipulations are also released by the National Institute of Advanced Industrial Science and
85_17
Technology and their co-workers (in a strict sense, OpenRTM-aist itself is a library and does not
85_18
include these tools).
85_19
RT-component
85_20
The RT-component is a functional unit which conforms to the RT-component specification defined by
85_21
OMG. In OpenRTM-aist, RTCs have data ports, service ports, and execution context which controls the
85_22
RTC's state.
85_23
State Machine
85_24
In standards of RT-component, RTC must have 4 states such as CREATED, INACTIVE, ACTIVE, and ERROR.
85_25
When the state changes, corresponding event-handlers are called by the execution context which
85_26
manages the RTCs' state machine.
85_27
For example, "on_activated" callback function is called when the RTC is activated (from INACTIVE to
85_28
ACTIVE state). In on_activated callback, initialization codes are implemented.
85_29
On the other hand, "on_deactivated" callback function is called when the RTC is deactivated (from
85_30
ACTIVE to INACTIVE state). In this callback, finalization codes are implemented.
85_31
"on_execute" is periodically called when the RTC is in ACTIVE state. Here, controlling or some
85_32
device management (ex., polling) functions are called.
85_33
These callbacks are called by the "execution context" object. If the special execution context is
85_34
attached to the RTCs, calling method or policy is modified (see execution context section).
85_35
Data port
85_36
A data port is an endpoint to communicate with other RTCs. The data ports have their types. Ports
85_37
with the same type can be connected to each other.
85_38
In OpenRTM-aist, primitive data types (like "TimedLong", "TimedDouble", and so on) are implemented.
85_39
Moreover, from OpenRTM-aist version 1.0, extra data types which are expected to be used commonly in
85_40
robotic systems were released as ExtendedDataType (like "TimedVelocity2D", "TimedPose2D", and so
85_41
on)
85_42
Developers can define their own data types by describing IDL file. Tools can parse the IDL file and
85_43
automatically generate the skeleton and stub file of the original data types.
85_44
Service port
85_45
The service port allows communicating much more flexibly than the data ports. Developers should
85_46
define service port interfaces by making their IDL files.
85_47
Execution contexts
85_48
Execution contexts handle the state-machine operations of RT-components. In OpenRTM-aist, several
85_49
kinds of execution contexts are provided. For example:
85_50
the periodic execution context, one of the most commonly used, provides periodic calls of the
85_51
"on_execute" event-handler (sensor acquisition or actuator control are usually implemented there);
85_52
the real-time execution context, which uses Linux's pre-emptive kernel function, supports
85_53
real-time operation of the RTC;
85_54
the extra trigger execution context is an important characteristic of OpenRTM-aist. It provides
85_55
the synchronization capability with dynamics simulators like OpenHRP-3.
85_56
Configuration
85_57
Configuration is a function which dynamically changes the parameters of the RTCs during run-time.
85_58
Configuration can be numeric and string.
85_59
Supported operating systems
85_60
OpenRTM-aist runs on Windows, Linux and macOS. Furthermore, VxWorks is supported experimentally.
85_61
Supported programming languages
85_62
Since OpenRTM-aist is based on the CORBA technology, it supports several programming languages,
85_63
including:
85_64
C++ Java Python Erlang (unofficial)
85_65
Tools RTC Builder
85_66
RTC Builder is a tool for skeleton-code generation. It is launched in the eclipse developmental
85_67
environment. OpenRTM-aist also supports RTC-template which is a command-line type skeleton-code
85_68
generation tool.
85_69
RT System Editor
85_70
RT System Editor is a tool for handling RTCs. RT system editor provides following services:
85_71
Referring RTCs' states Connecting RTCs' ports Configuring RTCs Activate/deactivate/reset RTCs
85_72
Save/restore the RT-system
