Existing approaches struggle to achieve such force-sensitive manipulation tasks. We propose a noisestatistics-based calibration-driven reflex control paradigm with vision-based tactile sensing: by analyzing the sensor’s intrinsic noise characteristics (via a brief static-hold-and-unload protocol), we directly derive all controller thresholds, eliminating external force calibration, trial-and-error manual tuning, or material-specific physical models. Instantiating this paradigm, we present TactileReflex, a three-channel closed-loop controller that extracts three image-level proxies, shear intensity (Sy), contact intensity (Fn), and center of pressure (C), from dual visuo-tactile sensors and drives prioritized reflex channels at ∼12 Hz for slip suppression, weight-adaptive release, and force protection. Each channel closes the loop directly on its proxy via noise-derived thresholds. Ablation demonstrates that only the full three-channel system is able to prevent irreversible container deformation (5/5 success vs. at most 1/5 for partial configurations). In a dynamic pouring task, fixed-effort baselines fail in all 10 attempts due to pose drift, while TactileReflex achieves 9/10 success across two water volumes. As a selfcontained and interpretable controller, TactileReflex can serve as a plug-and-play safety layer beneath high-level manipulation pipelines, including haptic-free VR teleoperation and visionlanguage-action (VLA) policies.  \nProject page: [https://shayfeng.github.io/TactileReflex/](https://shayfeng.github.io/TactileReflex/)  \nI. INTRODUCTION  \nManipulating deformable containers (soft plastic cups, thin-walled bottles, flexible pouches) is a daily task for humans yet remains challenging for robots. Consider a commonplace disposable plastic cup: it weighs only 3.5–5 g, its wall is just 0.3–0.5 mm thick, it is transparent (offering minimal visual contrast for external cameras), and the margin between the minimum force needed to prevent slip and the force that permanently crushes the cup is remarkably narrow. Now fill it with water and pour: the shifting liquid continuously redistributes the gravitational load along the gripper fingers, demanding real-time effort modulation that fixed-effort or open-loop grasping cannot achieve. The core difficulty is that grasp stability and object safety are tightly coupled: insufficient effort leads to micro-slip and drop, while only slightly more force causes irreversible deformation. A practical grasp controller must therefore (1) detect  \n1Thrust of Robotics and Autonomous Systems, The Hong Kong University of Science and Technology (Guangzhou), Guangzhou, China.  \n2 School of Mechanical Engineering, Shanghai Jiao Tong University, Shanghai, China.  \n∗ Corresponding author: Qiang Nie, [qiangnie@hkust-gz.edu.cn](qiangnie@hkust-gz.edu.cn).  \nand suppress incipient slip in real time, (2) reduce effort when the carried load decreases to prevent over-gripping, and (3) enforce a hard safety limit on contact force. The central challenge is ensuring grasp stability while preventing irreversible deformation during dynamic tasks.  \nLimitations of existing approaches. Force/torque sensors can provide continuous feedback for adaptive grasping, but typically require per-sensor calibration and are sensitive to mounting/compliance effects [1], [2] .
