SFD-6

Force Feedback Device

SFD-6 is a domestically produced high-performance serial force feedback device designed specifically for large-scale, multi posture interaction scenarios. With a compact and lightweight body design and biomimetic robotic arm architecture, it brings users a natural and smooth immersive force sensing interaction experience.

The device adopts a series mechanical structure optimized by ergonomics, perfectly fitting the motion characteristics of the human arm. While achieving a large working space, it greatly improves the flexibility and naturalness of operation, supports users to complete complex operations in a wide range and multiple angles in multiple postures, and adapts to various force feedback scenarios with high requirements for activity range.

Product Features

Pen Tip End

The universal pen tip design better accommodates ergonomic movement ranges, making it suitable for the vast majority of application scenarios.
Serial Mechanism

The movement of the serial mechanism is more flexible, and the movement space is large enough under the same size, resulting in a lighter overall weight.
Cartesian Coordinate System

SDK takes the fixed platform as the origin and can fully access the position and posture information of the joystick in space.
Gravity Compensation

Active gravity compensation+passive gravity compensation to increase user comfort when operating the device.
High Precision Force Feedback

3 degrees of freedom variable force feedback, feel the stiffness of virtual objects or the force exerted by robots from the end.
Easy to Operate

Directly use when powered on, no manual calibration required, handle button simulates virtual material grasping.
Operation and Translational Force Feedback

The device operation does not distinguish between left and right hands and can provide force feedback in the direction of spatial translation.
Two Handed or Multi Handed Operation

Provide SDK interface and implementation demo for dual/multi handed operation.
