Back to Barnraising: Why Hyperlocal Is The Future for Online Civic Engagement...ACTion Alexandria
Since we witnessed online organizing at its most winning during the 2008 Barack Obama presidential campaign, there have been a slew of online civic engagement ventures of national or even international scope--TwitterVoteReport and InaugurationReport, Ushahidi, Ashoka Changemakers, Ideas for America, Citizen Effect--the list goes on an on. And while many of these projects have been very successful, what they've made apparent is that what is often most difficult to do, is to help those living closest to us--in our town, on our street, on our block. The next generation of online civic engagement tools and platforms must address this most basic need--neighbors helping neighbors.
You can already see national platforms emerging that empower citizens to help their neighbors--NeighborGoods and SeeClickFix are great examples. Like place blogs, hyperlocal civic engagement projects like Front Porch Forum and Localocracy are taking civic engagement back to the future if you will,providing online tools and platforms for neighbors to help neighbors in their own communities. where they can witness the impact Neighbors are beginning to use these tools to identify themselves, reconnect, and generate collective action that transforms their communities. This future reflects a shift from projects that are large in scale and often disconnected from where we live and who we know. The age of local community barn raising is back, with a little help from the social web.

概要：リソース効率に優れた特徴点マッチングのための軽量なアーキテクチャ「XFeat（Accelerated Features）」を提案します。手法は、局所的な特徴点の検出、抽出、マッチングのための畳み込みニューラルネットワークの基本的な設計を再検討します。特に、リソースが限られたデバイス向けに迅速かつ堅牢なアルゴリズムが必要とされるため、解像度を可能な限り高く保ちながら、ネットワークのチャネル数を制限します。さらに、スパース下でのマッチングを選択できる設計となっており、ナビゲーションやARなどのアプリケーションに適しています。XFeatは、高速かつ同等以上の精度を実現し、一般的なラップトップのCPU上でリアルタイムで動作します。

セル生産方式におけるロボットの活用には様々な問題があるが，その一つとして 3 体以上の物体の組み立てが挙げられる．一般に，複数物体を同時に組み立てる際は，対象の部品をそれぞれロボットアームまたは治具でそれぞれ独立に保持することで組み立てを遂行すると考えられる．ただし，この方法ではロボットアームや治具を部品数と同じ数だけ必要とし，部品数が多いほどコスト面や設置スペースの関係で無駄が多くなる．この課題に対して音𣷓らは組み立て対象物に働く接触力等の解析により，治具等で固定されていない対象物が組み立て作業中に運動しにくい状態となる条件を求めた．すなわち，環境中の非把持対象物のロバスト性を考慮して，組み立て作業条件を検討している．本研究ではこの方策に基づいて，複数物体の組み立て作業を単腕マニピュレータで実行することを目的とする．このとき，対象物のロバスト性を考慮することで，仮組状態の複数物体を同時に扱う手法を提案する．作業対象としてパイプジョイントの組み立てを挙げ，簡易な道具を用いることで単腕マニピュレータで複数物体を同時に把持できることを示す．さらに，作業成功率の向上のために RGB-D カメラを用いた物体の位置検出に基づくロボット制御及び動作計画を実装する．
This paper discusses assembly operations using a single manipulator and a parallel gripper to simultaneously
grasp multiple objects and hold the group of temporarily assembled objects. Multiple robots and jigs generally operate
assembly tasks by constraining the target objects mechanically or geometrically to prevent them from moving. It is
necessary to analyze the physical interaction between the objects for such constraints to achieve the tasks with a single
gripper. In this paper, we focus on assembling pipe joints as an example and discuss constraining the motion of the
objects. Our demonstration shows that a simple tool can facilitate holding multiple objects with a single gripper.
