A soft-bodied fluid-driven amoeboid robot inspired by plasmodium of true slime mold
No full textAnimals exhibit astoundingly adaptive and supple locomotion under real world constraints. In order to endow robots with similar capabilities, we must implement many degrees of freedom into the robots' bodies equivalent to animals. For taming many degrees of freedom, the concept of autonomous decentralized control plays a pivotal role. However, a systematic way of designing such autonomous decentralized control system is still missing. Aiming at understanding the principles that underlie animals' locomotion, in our early studies, we focused on true slime mold, a primitive living organism, and extracted a decentralized control scheme. In order to validate this control scheme, this paper presents a soft-bodied amoeboid robot inspired by true slime mold. Significant features of this robot are twofold: (1) the robot has highly soft and deformable body stemming from real-time tunable springs and a balloon, the former is used for an outer skin of the body and the latter is for protoplasm; and (2) a fully decentralized control using coupled oscillators with completely local sensory feedback mechanism is realized by exploiting the long-distance interaction between the body parts stemming from the law of conservation of protoplasmic mass. Experimental results show that this robot exhibits highly supple locomotion without relying on any hierarchical structure. The results obtained are expected to shed a new light on design methodology for autonomous decentralized control system.査読付原著論文インパクトファクター(-)被引用回数(-
アジャイルソフトウェア開発PBLにおける形成的アセスメントの効果測定
Get PDF多くの情報系大学において，Project-Based Learning(PBL) が広く取り入れられ，その有効性や実践例が多数報告されている．ソフトウェア開発を行うPBL では，Scrum に代表されるアジャイル開発方法論を採り入れる大学が増加している．Scrum では，透明性・検査・適応の実践が求められるが，開発・マネジメント経験の少ない学生が透明性の確立，プロジェクトを検査・適応する難易度は高い．また，講義設計や学びの状況，質を改善するには，学習途中でそこまでの成果や達成度を把握し，学習を促す形成的な評価・アセスメントを行うのが望ましい．しかし，教育者がPBL 専任でない場合や，学生が時間外にも活動するなど，形成的な評価を行うには多くの課題がある．これらの課題解決を目指し，プロセスを評価し改善するモデルである能力成熟度モデル統合(CMMI) に着目した．本稿では，筆者らが提案するCMMI に基づいた，プロジェクト状況を検査可能な評価手法に対し，PBL における形成的アセスメント効果の検証について報告する．
Project-Based Learning (PBL) has been widely adopted in many information-oriented universities and its effectiveness and practical examples have been reported. In PBL that develops software, there are an increasing number of universities that adopt the Agile development methodology represented by Scrum. Although Scrum requires the practice of transparency, inspection, and adaptation, it is highly difficult for students with a little development and management experience to establish transparency and inspect and adapt projects. In addition in order to improve the situation and quality of lecture design and learning it is desirable to grasp the results and achievement so far during learning and to carry out formative evaluation and assessment that encourage learning. However, there are many problems in performing formative evaluation such as when each educator is not full-time PBL or overtime activities. In order to solve these problems, we focused on the Cability Maturity Model Integration (CMMI), which is a model to evaluate and improve the software process. In this paper we report the effectiveness of formative assessment in PBL using the evaluation method that can inspect our proposed the project situation based on CMMI

スマートフォンアプリケーション開発初心者向けユーザビリティ評価手法の提案
Get PDFアプリケーション開発において, ユーザビリティを配慮したUI(User Interface) デザインは重要になる. しかし, 開発初心者のユーザビリティについての知識が不十分な場合,UI デザインで時間を使い, 円滑にアプリケーションを作り上げることは困難である. また, ユーザビリティが不十分なまま作成を進めてしまうと, ユーザに負担を掛けてしまい, 満足度の高いアプリケーションとは言えない. そこで本研究では, ユーザビリティを配慮したUI デザインの支援システムを開発する. このシステムは開発中のアプリケーションビルドごとにUI デザインについての助言を表示する. このシステムを使うことで開発初心者は, 開発を行いながらUI デザインを円滑に決めることができ, 開発の負担を減らすことで問題の解決を図る.
UI design considering usability is important in application development. However, if the beginner’s knowledge of usability is insufficient, it is difficult to spend time in UI design and smoothly build an application. Further, if the usability is insufficient and the creation proceeds, it imposes a burden on the user and cannot be said to be a highly satisfactory application. Therefore, in this research, we develop a UI design support system that considers usability. This system displays UI design tips for each application build under development. By using this system, novice developers can smoothly decide UI design while developing, and try to solve problems by reducing development burden
ICTを用いた北海道新幹線内での新たな楽しみの提供に関する研究
Get PDF本研究では，北海道新幹線の乗客に新たな鉄道旅ならではの楽しみを提供するシステムの開発を行う．鉄道旅において，車窓からの景色はその醍醐味の1 つであり欠かせない要素である．北海道新幹線は札幌までの延伸が進んでおり，その総延長360.3km のうち74%にあたる265km がトンネル区間である．トンネル区間では車窓からの景色を楽しむことができないことや，またそれによってコミュニケーションをとるきっかけを1 つ失うなどの課題がある．既存の研究やサービスでは，鉄道旅ならではの楽しみが提供されていないことや，トンネル内では不向きなGPS が使用されるなど不十分な点がある．本研究では，BLE ビーコンやAR を用いた，トンネル内でも本来トンネル外にある景色を仮想的に体験できるシステムや，乗客同士が容易にコミュニケーションをとれるシステムの検討・開発によって，課題の解決を目指す．
In this research, we will develop a system that provide new only train trip pleasure for passenger on Hokkaido super express. The view from the train window is important and indispensable at train trip. Extension of Hokkaido super express to Sapporo is in progress, and that has a total length of 360.3 km, of which the total length of the tunnel is 265 km, which is 74% of the total length. Inside the tunnel, there are problems such as passenger are not able to enjoy view from the train window, and also causes one of the triggers of communication between passengers to be lost. And existing research or service is not enough, because those does not provide pleasure of trip by train, or because those use the GPS not suitable for use inside the tunnel. In this research, we aim to solve those problems by developing a system that capable of experience view outside of tunnel or capable of communicate passengers each other easily
