Embedded systems, such as smartphones, home appliances, and automotive cars, are widely used in various settings. Furthermore, demand for embedded systems continues to rise, driven by factors such as the aging population, declining birthrate, and the need to reduce labor costs in factories and companies. To address the shortage of C and C++ programmers and enhance the accessibility of embedded systems development, we propose a method that utilizes Node-RED, a visual programming tool. And then mruby/c, a language that combines the benefits of Ruby and C/C++, and enable even programming novices to develop embedded systems. We also incorporate Docker Compose to simplify the process of building a development environment, and release as a open source software. Our approach offers a promising solution for engineers seeking to improve their embedded systems development skills or those who want to enhance the productivity and readability of their code. By leveraging Node-RED and mruby/c, this study provides an innovative solution that can enable a wider range of developers to participate in embedded systems development, ultimately contributing to the growth of this field.

We have developed a visual programming tool called SmrAI for function testing, and investigated whether wrapping existing source code with Scratch Blocks is an effective means of mitigating the shortage of programming personnel in the manufacturing. SmrAI is based on Smalruby, which can convert Scratch Blocks into Ruby code. In addition, SmrAI introduces two new sets of Blocks that wrap existing Ruby libraries for function testing. Since existing tools and libraries were utilized, the cost of developing SmrAI was low, and there were no changes in the function testing procedure. We conducted a verification test using staff members who were familiar with the function testing process but had little or no programming experience, and confirmed that they were able to program using SmrAI and that they had confidence in its business applications. These results are expected to contribute to the diversification and increase of programming personnel responsible for function test programming.

One of the negative influence of climate change is the occurrence of large-scale disasters. All over the world, climate change-related disasters such as torrential rains, heavy snowfalls, floods, and landslides are occurring. For example, the number of torrential rains has increased 1.4 times in the last ten years and is increasing dramatically. In the case of a large-scale disaster, communication and power supply are not available; Typhoon No. 15 in 2019 caused a 20-day power outage in Chiba prefecture, Japan. The power outage also causes the carrier communication network inoperable, leading to a secondary disaster that prevented smooth evacuation instructions. A system that can stably collect weather data and provide evacuation instructions at public facilities in the case of a disaster would greatly contribute to disaster prevention. The authors developed a general-purpose communication module for LPWA-based communication and designed a protocol to build an autonomous mesh communication network. This paper describes the implementation of this developed system for a ground monitoring system using soil sensors and reports on the proof experiment.

This paper describes a system to support the management of medical devices in hospitals. It is used by medical staff to find medical equipment or to track the placement of medical equipment. This support system can measure indoor location using BLE and determine the location based on the measured signal strength. A BLE tag that periodically transmits a signal is attached to the medical device, and the signal strength of the BLE tag is measured by a BLE receiver placed indoors. A neural network is trained using the data set with the signal strength of the BLE tag as input and the room where the BLE tag is placed as output. Use the trained neural network to determine in real-time the room in which the BLE tag is placed.Many devices are emitting BLE signals indoors such as smartphone and wireless headphone. And the database collects the received strength of their signals when they are received by multiple BLE receivers. To prevent network congestion and keep the system running reliably, the signals of the necessary BLE tags must be filtered, and then many BLE tags are processed by lightweight Bloom filter.We were able to implement a system that detects and also tracks the location of BLE tags in real-time.

In IoT software development, a method to implement software by focusing on data flow has been proposed, which is called dataflow programming. On the other hand, sensor devices are generally implemented in microcontrollers with limited resources for compactness, power savings and costs, so sensor devices are not suitable for executing data flow programs. In this paper, an environment running the scripting language mruby is described to execute a dataflow program on a small microcontroller. The execution of the data flow program is performed asynchronously by multiple nodes, which handle the sensor data. The execution environment of a dataflow program must support this style of execution. Since mruby can execute multiple programs concurrently, it is well suited to implement dataflow programs. By generating mruby code from a program developed in Node-RED, one of the popular dataflow programming environments, the mruby program is executed on a single-chip microcontroller, which includes mruby virtual machine.

© 2019, Springer Nature Switzerland AG. This paper describes a hardware acceleration of language processing system in scripting programming languages. Scripting programming languages are high development efficiency since which is easy to write and high source code readability. On the other hand, embedded software developments take a lot of time and the difficulty level is high. We think that it is good to use scripting programming languages in embedded software developments for the improvement of development efficiency. However, scripting programming languages require many hardware resource such memory and their execution speeds are slower than procedural languages such as C language. Therefore, we propose a hardware acceleration of language processing in scripting programming languages. Hardware acceleration technology can improve the processing performance of scripting programming languages by a pipeline processing. We focus on a scripting programming language ‘mruby/c’ for embedded software developments. We implemented the hardware which performs the memory management and the instruction decoder in mruby/c. In this paper describes results of implementation of the hardware acceleration and the performance evaluation.

© Springer International Publishing AG, part of Springer Nature 2018. Embedded systems are systems in which hardware and software are closely linked. We’ve already released mruby, which is a programming language for embedded software development [1, 2]. The language syntax of mruby is same as Ruby which is well known as higher productivity by web application developers [3]. Using mruby, we can code applications in embedded system easily [4]. Recently IoT, which connects sensor devices and internet, is widely users in many industrial areas. In IoT applications, several different kind of sensors is controlled by embedded software and its data is transferred to the internet. Such concurrent accessing to sensor devices are obviously complicated. We design the concurrent processing mechanism in mruby. In this paper, we show the result of concurrent execution and the key point in resource accessing.

This paper shows development of lightweight Ruby which is a subset of program language Ruby. Lightweight Ruby aims at mainly using Ruby for the software development of an embedded system. Few resources, the mechanism of hardware control, a real-time operation, etc. are required for an embedded system. Lightweight Ruby is designed in consideration of these demands. The advantages of using object oriented programming for the development of an embedded system and the problems with the conventional programming language are clarified. This problem can be solved if Ruby is used for the development of an embedded system. Implementation of lightweight Ruby in FPGA is also shown. © 2011 IEEE.

In recent years, we treat various electronic documents in a computer. This makes reuse and redistribution convenient. However, the information on electronic data has risks. We propose the technology of dividing information safely and managing it for avoiding of this problem. This technology is designed based on the algorithm of mathematical information division. The features of this technology are conditions which restore the divided information. For example, original information is divided into N blocks. The divided block required in order to restore this information is M pieces (M > =N). It is impossible to restore the original information in less than M blocks. This technology is realized by M-1 degree equation. Original information is intercept of the equation, and N number points one the equation are divided data. We program this technology, and implement the application which put together this technology and AES[1] (AES: Advanced Encryption Standard). © 2011 IEEE.

This paper presents the relative position estimation of multi-agent robots by using omnidirectional panoramic vision in simulated cyber space. It is more accurate and powerful to use multiple robot agents to estimate the relative position of a single agent rather than by using another agent. However, there are many limitations, including a minimum space for constructing the system and the high initial cost for installing hardware robot agents. In this study, to resolve such constraints, multiagent robots were operated in Microsoft Robotics Developer Studio simulation space for the estimation of relative locations.

However well we control a walking bipedal robot, the images obtained by a camera are tilted to the left or right, and have small irregularities. This complicates the recognition of an environment by using a camera in a walking robot when the robot cannot move smoothly. The reason for using a bipedal robot is to make the robot as similar as possible to a human in body shape and behavior in order to make collaboration easier. This is difficult to attain with other types of robot such as wheel-driven robots (Sato et al. AROB2008; Fujiwara et al. WMSCI2009). In an artificial environment which mainly consists of vertical and horizontal lines, the tilt angle of camera images must be corrected by using the Hough transformation, which detects lines which are nearly vertical (Okutomi et al. 2004; Forsyth and Ponce 2007). As a result, the robot can successfully recognize the environment with stereo vision using images obtained by correcting the tilted ones. © 2010 International Symposium on Artificial Life and Robotics (ISAROB).

However well we control a bipedal robot in walking, images gotten by the cameras are tilted by left or right swing and small bumps. This complicates recognition of environment by using cameras in walking, and the robot can't move smoothly. Introducing a bipedal robot is to make it possible for both a human and the robot which have the same embodiment to make collaboration by making both take the same behavior as far as possible which is difficult to attain with other types of robots such as a wheel driven robot. Under the artificial environment mainly consisting of vertical and horizontal lines, images must be corrected by detecting the tilt angle of them using Hough Transformation, which detects nearly-vertical lines from artificial environment. As a result, a robot successfully recognizes the environment with a stereo vision using images obtained by correcting tilted ones. © 2010 ISAROB.

It is important to look for alternative forms of physical movement of people and equipments in order to assure diagnosis and maintenance tasks, especially in an environment where workers are subject to danger. An evident and classical solution is the use of the tele-operation and tele-robotics. If the tele-operation helps to solve a lot of real and technical problems, it still remains insufficient to assure an appropriate remote diagnosis and maintenance. The use of virtual reality techniques with the tele-operation can be the solution for an effective remote maintenance and diagnosis. In this paper we show the inefficiency occurred with the use of only tele-operation in the remote maintenance, we introduce our original new system where we use virtual reality techniques and 2D-3D matching (2D camera image-3D virtual objects) with tele-operation to remotely collect machinery vibration data. We explain its structure, implementation and its advantages. We finished by experimenting the system, measuring the different operating times and precision and discuss the results.
