Visuotactile sensors typically employ sparse marker arrays that limit spatial resolution and lack clear analytical force-to-image relationships. To solve this problem, we present MoiréTac, a dual-mode sensor that generates dense interference patterns via overlapping micro-gratings within a transpare…
Transparent objects are common in daily life, while their optical properties pose challenges for RGB-D cameras to capture accurate depth information. This issue is further amplified when these objects are hand-held, as hand occlusions further complicate depth estimation. For assistant robots, howeve
Visuotactile sensors provide high-resolution tactile information but are incapable of perceiving the material features of objects. We present UltraTac, an integrated sensor that combines visuotactile imaging with ultrasound sensing through a coaxial optoacoustic architecture. The design shares struc
Most vision-based tactile sensors use elastomer deformation to infer tactile information, which can not sense some modalities, like temperature. As an important part of human tactile perception, temperature sensing can help robots better interact with the environment. In this work, we propose a nove…
Magnetic actuation system manipulates micro soft or rigid robots by a controllable magnetic field to move them freely in the narrow or enclosed space, which has demonstrated its huge potential in medical interventional surgery and drug delivery. However, the limited working space of paired or area-c
