Dual-Arm SDA-Series robots: Next-generation speed, application flexibility
Quick and agile, with “human-like” flexibility of movement, the Motoman Slim Dual Arm (SDA-series) robots provide the reach, payload, speed, performance, and flexibility required to perform a myriad of assembly, handling, machine tending, packaging, and part transfer applications that formerly could be done only by people. SDA-series robots feature 15 axes of motion (7 axes per arm, plus a single axis for base rotation). Internally routed cables and hoses reduce interference and maintenance, and also make programming easier.
Both robot arms can work together on one task to double the payload or handle heavy, unwieldy parts, trays, or pallets. The robot can also lift much more than its payload capacity when using a jib crane or other lift assist device.
The ability to use dual independent arms to process parts reduces the need for expensive custom fixturing and makes end-of-arm tooling simple and less costly. SDA-series dual-arm robots can hold a part with one arm while performing operations on the part with the other arm. Parts can be turned over by a simple hand-to-hand transfer with no need to set the part down or add additional hardware.
The actuator-based design of the SDA-series robots means that the motor, encoder, reducer, and brake for each robot axis are combined into one small, lightweight yet powerful package that is significantly smaller than a traditional ac servo motor drive. Advantages include a slim arm profile, lightweight robot body, and high wrist moment and inertia ratings attractive to service and entertainment applications.
SDA-series robots are available with the new FS100 controller or the DX100 controller. The FS100 is Yaskawa Motoman’s new compact, powerful, and open controller that is designed for small parts handling and assembly applications.
SIA-Series Robots: Lean, powerful 7-axis arms
Motoman Slim Individual Arm (SIA-series) robots feature what the company calls a revolutionary actuator-based 7-axis design, allowing arms to maneuver in very tight areas. Featuring best-in-class wrist performance, these versatile robots open up a wide range of industrial applications and are ideal for nut running, assembly, injection molding, machine tending, and a host of other applications, Motoman said.
Extreme motion flexibility allow these slim manipulators to be positioned out of the normal working area (such as floor-, ceiling-, wall-, incline- or machine-mounted) and reduce floor space requirements.
SIA5, SIA10, and SIA20 models are now compatible with the new FS100 controller. The FS100 is Yaskawa Motoman’s new small, powerful, and open controller that is designed for small parts handling and assembly applications. The FS100 is small enough to be mounted under a conveyor or in other space-saving locations.
At Automate 2013, the SIA10 robot performed collaborative assembly. This new application demonstrates the ability of robots and humans to share space and perform cooperative work in a safe manner and conforms to safety standards.

With payloads from 20-600 kg, Yaskawa Motoman’s dynamic, high-speed HP-series “High-Performance” robots are extremely versatile manipulators that excel at a wide variety of applications, including welding and machine tending. HP-series robots can also be used for assembly, packaging, palletizing, dispensing, and other tasks. Full six-axis flexibility also allows them to perform complex handling motions and other operations in a multi-function workcell. Heavier-payload models are often used in jigless applications where the HP robot serves as a highly flexible positioner, manipulating the part for processing by up to seven additional robots—all controlled by one Motoman multiple robot controller.
HP-series robots are compact and require minimal installation space. They can be placed close together to reduce overall floor space requirements or placed close to conveyors and other equipment to improve part/product accessibility. HP robots can be floor-, ceiling-, or shelf-mounted to provide highly flexible layouts, and extended-reach versions are available.
HP-series robots are controlled by the Motoman DX100 controller that includes patented multiple robot control technology to easily handle multiple tasks and control up to eight robots (72 axes), I/O devices, and communication protocols. Featuring a robust PC architecture with unmatched memory capacity, the DX100 uses a Microsoft Windows CE programming pendant with color touchscreen. The energy-saving DX100 controller features faster processing speeds for smoother interpolation, advanced robot arm motion, built-in collision avoidance, quicker I/O response, and accelerated Ethernet communication. Its extensive I/O suite includes integral PLC and HMI pendant displays, 2,048 I/O, and a graphical ladder editor that can provide system level control. The DX100 controller supports all major fieldbus networks. It is compliant to ANSI/RIA R15.06-1999 and other relevant ISO and CSA safety standards.
The HP20 robot (20 kg) can also be controlled by the FS100, a compact, powerful, and open software architecture controller.

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.

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.
