The Force Dimension lambda7 is the most recent addition to the Force Dimension family of haptic devices. Introducing a larger base compared to the sigma7, this device also offers seven active degrees of freedom in translation, rotation, and grasping.
This new device has been specifically designed for OEM applications and can be easily customised for integration in surgical consoles. The new wrist also provides three active degrees of freedom, with the last degree being the roll angle. This new configuration design of the wrist joints facilitates the integration with surgical robot systems. Finely tuned to display perfect gravity compensation, the force-and-torque-feedback end-effector offers extraordinary haptic performance. This enables instinctive interaction with complex haptic applications. The lambda7 device is available in left- and right-hand configurations and is designed for integration in bimanual workstation consoles.
Distinctive Design Features
Finely built around its unique parallel kinematics structure, the lambda7 device is designed for performance. Its superior mechanical stiffness is combined with its real-time USB 2.0 controller. This 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. 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 lambda7 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 lambda7.
Application Development
A powerful SDK provides highly advanced control over all Force Dimension devices in both haptics and robotics modes. 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. These 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.
