Reconfigurable Robotics Lab presents “Digits” – a comprehesinve design and control framework for reconfigurable haptic feedback.
Researchers from the Reconfigurable Robotics Lab and Eindhoven University of Technology (TU/e) have developed a modular framework designed to advance haptic feedback technologies for applications in virtual reality, rehabilitation, and beyond.
Haptic feedback devices simulate the sense of touch in digital environments and serve a critical role in immersive virtual experiences and physical rehabilitation. However, many current systems are tailored to specific use cases, which limits their adaptability. Digits addresses this limitation through a comprehensive, reconfigurable design and control system based on soft robotic modules that adapt their shape and stiffness dynamically.
Digits introduces a new paradigm of customizable, scalable, and intelligent haptic devices. It can be reshaped and reprogrammed for different applications from VR gaming gloves to assistive rehabilitation tools without needing an entirely new device.
Modular Soft Robotics with Pneumatic Actuation
Interchangeable modules enable diverse configurations, from finger-mounted devices (TangiGlove) to handheld devices (TangiBall). Soft, inflatable pouches generate tactile sensations with controllable stiffness and motion. Experimental evaluations demonstrated precise pressure control, high force output (up to 3.5 N), and high-frequency response (up to 30 Hz).
Intuitive Control and User-Centric Interaction Features with Feelix
The integrated software tool allows intuitive haptic effect design and real-time control using visual interfaces and interaction detection with built-in machine learning.
