OpenEL(Open Embedded Library)

OpenEL is an open platform to standardize the specifications of the software implementation of robotics and control systems.

Current Problems in Embedded System Development

Currently, porting existing software on different systems, including the device driver in the development of embedded systems has been considerable effort required. For example, turning on the LED or just to operate the motor on different hardware, there may spend many days. Because an application program interface to control the output of the sensors and motors, were each uniquely defined by the device manufacturer, has been implemented since.

Therefore, JASA propose to unify these interfaces which were different for each device manufacturer. JASA focus on robotics and control systems, has started drafting specifications OpenEL for Robots. In OpenEL for Robots, by the base portion of the software platform for robotics and control systems, and aims to enable applications running on different hardware too soon. This increases the portability and reusability of the software, resulting in improved quality, lower costs and lead to improved productivity is expected to improve convenience for users and developers.

Why OpenEL?

There are lots of problems in ROS and RT Middleware. For examples, Limitation of Software Development Environment.

  • OS, Languages etc.
  • No standard to use Sensors and Motors etc.
  • No standard to use A/D, D/A, DIO etc.

In non-competitive areas, we often have a lot of trouble. OpenEL solves above problems.

Specifically, OpenEL is API (Application Program Interface) standardized on the layer below the middleware. It is a mechanism for device control, such as the output to the motor, the input from the sensor and so on.

Advantage of OpenEL

  • OpenEL is new Application Programming Interface for Robots and Embedded Devices.
  • OpenEL redefine embedded system programming.
  • Very Easy Naming Convention for programmer.
  • OpenEL standard to use Sensors and Motors etc.
  • OpenEL standard to use A/D, D/A, DIO etc.
  • In non-competitive areas, we will never have any trouble.
  • OpenEL improves software portability, reusability and productivity.

Architecture of OpenEL

OpenEL has two layer, Surface and Component layer.

Figure. Architecture of OpenEL

Surface Layer

Application software developers use the API(Application Programming Interface) that is defined in the Surface Layer. By using only the API defined in the Surface Layer, application software developers will be possible to build software without being conscious of the difference of the device hardware.
JASA will have the right to make the revision, add, change or delete a specification.

Component Layer

Application software developers do not need to be aware of the presence of the Component layer. Along with the hardware, such as sensors and motors, Component layer, is provided by the supplier or manufacturer of the device for each device you want to use. Component layer is a bridge to the actual operation of the device from the API of the Surface Layer. Component layer is also good in the actual condition of the process that includes device driver software, and is also good in the wrapper function of the device driver software.
