| The sigma.7 is the most advanced master haptic interface ever designed by Force Dimension. Introducing a redesigned delta base, the sigma.7 introduces 7 active degrees-of-freedom, including high precision active grasping capability. Finely tuned to display perfect gravity compensation, the force-and-torque-feedback end-effector offers extraordinary haptic performance, enabling instinctive interaction with complex haptic applications. Designed for advanced aerospace and medical industries to enable elaborate control of dexterous robots, its highly ergonomic and distinctive design make the sigma.7 the reference device for safety-critical applications. The sigma.7 is available in left- and right-hand configuration and can be integrated in a dual workstation setup for bimanual operation. |  |

Unique Design Concept Finely built around its unique parallel kinematics structure, the sigma.7 device is designed for performance. Its superior mechanical stiffness, combined with its real-time USB 2.0 controller, enables the rendering of high contact forces at a rate attaining 8 KHz. To provide the highest degree of haptic transparency, accurate gravity compensation is maintained in translation and orientation space by perfectly coupling passive and actuated components together. Each system is individually calibrated to ensure repeatable and optimal precision and performance. Its unique kinematics design perfectly decouples translations and rotations, enabling the sigma.7 to exceed the requirements of the most demanding applications. Force Dimension also provides advanced technical support for dedicated applications that require custom end-effectors for the sigma.7. |

Application Development A powerful SDK provides highly advanced control over all Force Dimension devices, including the sigma.x, omega.x and delta.x series, in both haptics and robotics mode. The Haptics SDK offers all the basic functions to read positions and to program desired forces in Cartesian space. Expanding these fundamental capabilities, the Robotics SDK leverages the Haptic SDK by introducing an advanced set of real-time routines to precisely control the position of the device. The Force Dimension SDK provides support for multi-threaded, multi-device programming and is available on a wide range of platforms including Windows, Linux, Mac OS X and QNX, in both 32- and 64-bits editions. The combination of both haptics and robotics capabilities into a single unified framework allows developers to create powerful collaborative interfaces between people and machines. Swiss Design and Manufacturing From precisely driving a catheter inside the heart of patient to finely operating a robotic manipulator in micro-gravity, Force Dimension has successfully integrated its haptics hardware and software technology into some of the most critical applications, where failure simply is not an option. To consistently meet such high standards, Force Dimension carefully controls every step involved in the design, engineering and manufacturing of all of its systems, and routinely works with some of the most qualified and talented R&D teams from a wide range of industries and research institutions. Over the years, these efforts have lead to the development of many exciting new applications with possibly some of the finest haptic devices ever made. |
