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.

出典:Guilherme Potje, Felipe Cadar, Andre Araujo, Renato Martins, Erickson R. ascimento: XFeat: Accelerated Features for Lightweight Image Matching, Proceedings of the 2024 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR) (2023)
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。

• AWS supports the following image formats for importing both disks and VMs into
Amazon EC2:
• RAW format for importing disks and VMs.
• Dynamic Virtual Hard Disk (VHD) image formats, which are compatible with Microsoft Hyper-V
and Citrix Xen virtualization products. VHDX images are not currently supported.

17. Known Limitations for Importing a VM
into Amazon EC2 Using ImportImage (1)
• You can have up to twenty import image or snapshots tasks in progress at the same time
per region. To request an increase to this limit, contact AWS Support. Tasks must complete
within 7 days of the start date.
• Imported VMs create Amazon EC2 AMIs that use Hardware Virtual Machine (HVM)
virtualization. Creating AMIs that use Paravirtual (PV) virtualization using VM Import is not
supported. Linux PVHVM drivers are supported within imported instances.
• Imported Red Hat Enterprise Linux (RHEL) instances must use Cloud Access (BYOL)
licenses.
• Imported Linux instances must use 64-bit images. Importing 32-bit Linux images is not
supported.
• Imported Linux instances should use default kernels for best results. VMs that use custom
Linux kernels might not import successfully.
• Typically, you import a compressed version of a disk image; the expanded disk image
cannot exceed 1 TiB.
2015/5/11 17
18. Known Limitations for Importing a VM
into Amazon EC2 Using ImportImage (2)
• Make sure that you have at least 250 MB of available disk space for installing drivers and
other software on any VM you want to import into an Amazon EC2 AMI running Microsoft
Windows or Linux.
• Multiple network interfaces are not currently supported. When converted and imported,
your instance will have a single virtual NIC using DHCP for address assignment.
• Internet Protocol version 6 (IPv6) IP addresses are not supported.
• For vCenter 4.0 and vSphere 4.0 users, remove any attached CD-ROM images or ISOs
from the virtual machine.
2015/5/11 18
19. Known Limitations for Importing a VM
into Amazon EC2 Using ImportImage (3)
• VMs that are created as the result of a P2V conversion are not supported by Amazon EC2
VM import. A P2V conversion occurs when a disk image is created by performing a Linux
or Windows installation process on a physical machine and then importing a copy of that
Linux or Windows installation into a VM.
• Amazon VM Import does not install the single root I/O virtualization (SR-IOV) drivers
except for imports of Microsoft Windows Server 2012 R2 VMs. These drivers are not
required unless you plan to use enhanced networking, which provides higher
performance (packets per second), lower latency, and lower jitter. To enable enhanced
networking on a c3 or i2 instance type after you import your VM, see Enabling Enhanced
Networking on Linux Instances in a VPC. For Microsoft Windows Server 2012 R2 VMs, SR-
IOV driver are automatically installed as a part of the import process.

20. Known Limitations for Importing a VM
into Amazon EC2 Using ImportImage (4)
• In connection with your use of your own Microsoft licenses, such as through MSDN, to
run Microsoft Software on AWS through a bring your own license (BYOL) model:
• (細かいので、以下省略)
• ドキュメントを確認してください
• ライセンスのことは、ADSJさんや日本マイクロソフトさんもしくはライセンスの販売店さん
に確認しましょう
• 思い込みで判断すると火傷する可能性高い、と思います

32. 2.移行する仮想マシンの準備(共通)
• Disable any antivirus or intrusion detection software on your VM. These services can be
re-enabled after the import process is complete.
• Uninstall the VMware Tools from your VMware VM.
• Disconnect any CD-ROM drives (virtual or physical).
• Set your network to DHCP instead of a static IP address. If you want to assign a static
private IP address, be sure to use a non-reserved private IP address in your VPC subnet.
Amazon Virtual Private Cloud (Amazon VPC) reserves the first four private IP addresses in
a VPC subnet.
• Shut down your VM before exporting it from your virtualization environment.
2015/5/11 32
33. 2.移行する仮想マシンの準備 (Windows) (1)
• Enable Remote Desktop (RDP) for remote access.
• Make sure that your host firewall (Windows firewall or similar), if configured, allows access to
RDP. Otherwise, you will not be able to access your instance after the import is complete.
• Make sure that the administrator account and all other user accounts use secure
passwords. All accounts must have passwords or the importation might fail.
• Make sure that your Windows VM has .NET Framework 3.5 or later installed, as required
by Amazon Windows EC2Config Service.
• You can run System Preparation (Sysprep) on your Windows Server 2008 or Windows
Server 2012 VM images before or after they are imported. If you run Sysprep before
importing your VM, the importation process adds an answer file (unattend.xml) to the VM
that automatically accepts the End User License Agreement (EULA) and sets the locale to
EN-US. If you choose to run Sysprep after importation, we recommend that you use the
Amazon EC2 Config service to run Sysprep.
2015/5/11 33
34. 2.移行する仮想マシンの準備 (Windows) (2)
• Disable Autologon on your Windows VM.
• Make sure that there are no pending Microsoft updates, and that the computer is not set
to install software when it reboots.
• Apply the following hotfixes:
• You cannot change system time if RealTimeIsUniversal registry entry is enabled in Windows
• https://support.microsoft.com/ja-jp/kb/2922223
• High CPU usage during DST changeover in Windows Server 2008, Windows 7, or Windows
Server 2008 R2
• https://support.microsoft.com/ja-jp/kb/2800213
• Enable the RealTimeIsUniversal registry.
2015/5/11 34
35. 2.移行する仮想マシンの準備 (Linux)
• Enable Secure Shell (SSH) for remote access.
• Make sure that your host firewall (such as Linux iptables) allows access to SSH. Otherwise,
you will not be able to access your instance after the import is complete.
• Make sure that you have configured a non-root user to use public key-based SSH to
access your instance after it is imported. The use of password-based SSH and root login
over SSH are both possible, but not recommended. The use of public keys and a non-root
user is recommended because it is more secure. VM Import will not configure an ec2-user
account as part of the import process.
• Make sure that your Linux VM uses GRUB (GRUB legacy) or GRUB 2 as its bootloader.
• Make sure that your Linux VM uses a root filesystem is one of the following: EXT2, EXT3,
EXT4, Btrfs, JFS, or XFS.
