Program Yaskawa Motoman robots with ROS Industrial open-source software and NI LabVIEW
A new Yaskawa Motoman Robotics Library (YMRL) for National Instruments LabVIEW 2012 facilitates the programming of Motoman robots into applications using the LabVIEW graphical interface. LabVIEW users can now readily integrate Motoman robots into production or quality control applications.
Support for the ROS-Industrial framework has been expanded to include the FS100 controller. Researchers developing new robotics algorithms or applications can now adopt any Motoman robot into their work.
“Yaskawa Motoman is working to democratize robotics. Historically, the industry approach has been based on proprietary languages. The users were expected to know the robot OEM’s language or learn it,” said Erik Nieves, technology director. “We believe this has stunted the adoption of robotics into new markets. Instead, we continue to introduce new means to program our robots including [Rockwell Automation] RSLogix, [NI] LabVIEW, and ROS Industrial [an open-source industrial robotics package from Southwest Research Institute (SwRI), an independent, nonprofit applied research and development organization. ROS stands for robot operating system.]. These well-established programming frameworks are familiar to users in various markets and will accelerate the growth of robotics into new areas.”
The multiple language approach can be seen performing a variety of new applications at Automate 2013.
Yaskawa Motoman FS100 Controller: Powerful controls, open software, compact package
The new high-performance Yaskawa Motoman FS100 controller is designed with open software architecture and supports PCI Express, C#, C++, .NET, ROS-Industrial, NI LabVIEW, and Motoman INFORM III. The FS100 enables OEMs, machine builders, and integrators to develop their customized software solutions.
"To meet the growing needs of our customers, it is often necessary to create custom functionality for the robot controller. The FS100 design leverages hardware standards and open software to allow easy extensibility of the controls,” said Erik Nieves, Technology Director at Yaskawa Motoman. “It is now possible for users or system integrators to easily integrate off-the-shelf hardware or write value-added functions to the robot controller.”
Designed for packaging, assembly, and material handling applications, the FS100 controller is compatible with Motoman robots with payloads up to 20 kg, including the high-speed MPP3 delta-style robot.
Next-generation Yaskawa Motoman DX100 Controller: Multi-robot, system-level controls
Using patented multiple robot control technology, Yaskawa Motoman’s next-generation DX100 controller easily handles multiple tasks including control of up to eight robots (72 axes), as well as I/O devices and communication protocols. The energy-saving DX100 features faster processing speeds, advanced robot arm control for smoother interpolation, built-in collision avoidance, and quicker I/O response. These advanced control functions take advantage of Yaskawa’s Sigma-5 motor technology to optimize acceleration characteristics and reduce cycle time.
Featuring a robust PC architecture, the DX100 uses a Microsoft Windows CE programming pendant with color touchscreen. Multiple window display capability and a unique cross-shaped navigation cursor reduce teaching time by 30%, and program files can now be up to 32 characters long. A convenient compact flash slot and USB port facilitate memory backups. All operator controls are located on the pendant, allowing the control cabinet to be mounted remotely. Connections to the controller cabinet are made through the back of the unit, optimizing floor space. The space-saving control cabinet allows for up to three external axes and can be remote-mounted. Top- or side-mount expansion options are available. The DX100 conserves power during robot idle time, providing up to 25% energy savings.
Its extensive I/O suite includes integral PLC and HMI pendant displays, 2,048 I/O, and a graphical ladder editor that can provide an efficient system level control. The DX100 supports all major fieldbus networks and offers easy connection to an information infrastructure through standard network options for EtherNet/IP, DeviceNet, Profibus-DP, and others.
The DX100 controller is compliant to ANSI/RIA R15.06-1999, ISO 10218-1-2007, and other relevant safety standards. It includes dual-channel E-Stop functionality, integrated speed monitoring, and manual brake release for the robot. An optional third-party certified Functional Safety Unit provides user-defined zone control and axis limits, plus speed and stopped-state monitoring. By minimizing the robot’s restricted space, these features can be used to reduce the cell floor space requirements.
By often eliminating the need for a separate PLC and human machine interface (HMI), the DX100 controller delivers significant cost savings at the system level, while also decreasing workcell complexity and improving overall reliability.
The DX100 has a reducer status check function that facilitates predictive maintenance. It also provides enhanced troubleshooting and alarm recovery, and a 20% improvement in mean time to repair (MTTR).
Laser seam-tracking and seam-finding software packages enhance welding precision
Yaskawa Motoman MotoEye LT laser seam-tracking and the new MotoEye SF seam-finding software packages are for arc welding applications using Servo-Robot’s laser cameras. MotoEye SF is a high- speed Ethernet interface developed for Servo-Robot’s SF-D laser camera series. This package provides an easy-to-use instruction to read in data from the camera, including joint offset and joint geometry information. This information can be used to adapt the robot weld path and parameters for parts with varying location and fit-up. The seam-finding data can be combined with ComArc through-arc-seam-tracking sensor to provide preview adaptive capability for lower cost than the real-time laser tracking cameras.
MotoEye LT enables Motoman robots to precisely track weld joints at high speeds and in real time, even while the parts are turning on a coordinated positioner. The software provides significant advantages when welding circumferential welds around fuel tanks or similar vessels. Additionally, the software has adaptive capability to vary the weld conditions based on joint gap information from the sensor, resulting in precise, optimized, highly accurate welds.
MotoEye LT has been available for Motoman XRC and NX100 controllers, and has been enhanced for the DX100 controller. This latest version features a high-speed Ethernet interface between the DX100 controller and Servo-Robot’s RoboNet Master camera controller. User-friendly programming menus take advantage of features built into the DX100 controller programming pendant. The Servo-Robot laser cameras are designed to withstand the welding environment and are not affected by ambient lighting or material surface conditions.
