Force Dimension - Model Sigma.7 - Haptic Interface for Advanced Aerospace and Medical Applications
The Sigma.7 by Force Dimension represents a pinnacle in haptic interface engineering, marked by its innovative redesign featuring a delta base capable of offering seven active degrees of freedom. It's unique in providing high-precision force-feedback grasping, optimized through superior mechanical stiffness, which, alongside its real-time USB 2.0 controller, supports rendering high-contact forces at up to 4 KHz. Designed to deliver exceptional, instinctive interaction for complex applications, it features a remarkable gravity compensation mechanism that maintains haptic transparency in both translation and orientation. Its ergonomic design and enhanced mechanical architecture make it ideal for safety-critical aerospace and medical environments. Notably, Sigma.7 is the only 3D force-feedback device certified for space usage, available in configurations for left or right-handed users, and adaptable for dual workstation setups. Force Dimension extends robust technical support and customization for application-specific end-effectors.
The sigma.7 is the most accomplished master haptic interface ever designed by Force Dimension. Introducing a redesigned delta base, this device is the first commercial haptic interface to offer seven active degrees of freedom, including high-precision force-feedback grasping capabilities.
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 also the first and only commercial 3D force-feedback interface to have ever been certified and used in space.
The device is available in left- and right-hand configuration and can be integrated in a dual workstation setup for bimanual operation.

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 4 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. |
A powerful SDK provides highly advanced control over all Force Dimension devices 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, macOS, QNX and VxWorks. The combination of both haptics and robotics capabilities into a single unified framework allows developers to create powerful collaborative interfaces between people and machines.
