    SLA: Scaling spatial-language-action models via continual pre-training

    The study proposes SLA, a spatial-language-action model initialized from a pretrained pi05 policy, which jointly optimizes action prediction and the alignment of intermediate visual embeddings with the spatial representations of a frozen 3D perception model during continual pre-training. The team unified heterogeneous robot datasets spanning embodiments, tasks, and scenes, and introduced feature-dependent gates that adaptively aggregate visual embeddings from multiple layers; the teacher model can use partially available depth and camera calibration information. All auxiliary components are used only during training, and the inference architecture remains unchanged.

    NeurIPS 2026 Paper RePO-VLA: Dual-Arm Robot Disturbance Recovery Success Rate Raised to 75%

    Sun Yat-sen University, Peng Cheng Laboratory, and other institutions propose RePO-VLA, which segments recovery trajectories, trains a progress-aware semantic value function, and performs value-conditioned fine-tuning so that dual-arm VLA policies can continue advancing tasks after disturbances. The study also builds FRBench, a failure-recovery benchmark; the RoboTwin simulation contains 46 dual-arm tasks and 23,453 trajectories. On real robots in water-pouring and towel-folding tasks, as recovery demonstrations per task increase from 50 to 200, the average disturbed success rates are 30%, 65%, and 75%, respectively.

    MIT proposes UQ-DAAAM to correct erroneous object descriptions in robot memory using multi-view images

    MIT researchers propose the UQ-DAAAM system, which quantifies a robot's uncertainty about what it sees by comparing multiple descriptions of the same object from different viewpoints, selects additional viewpoints to correct erroneous annotations, and writes the corrections back to memory. The method adds uncertainty quantification to the DAAAM framework, uses heuristic rules to select frames that can reduce uncertainty without rerunning the vision-language model, and then uses a large language model to fuse the multiple descriptions.

    DRAP: Dynamics-Risk Adaptive Plasticity for Continual Learning in Physical AI

    The study proposes DRAP, a replay-free continual learning method that uses locally trajectory-amplified, risk-weighted action gradients to estimate the historical importance of model tensors and scales each tensor's effective AdamW learning rate accordingly. The method is instantiated on OpenVLA's KappaTune subnetwork and sequentially adapted on the LIBERO Spatial, Object, and Goal suites; compared with standard AdamW fine-tuning and EWC, it markedly improves retention of old behaviors while maintaining the ability to learn new suites.

    GhostTac: Contactless Manipulation of Robot Tactile Sensors via Electromagnetic Interference

    GhostTac proposes a contactless attack that exploits the nonlinear rectification and limited-bandwidth amplification effects of electromagnetic interference (EMI) to convert carefully crafted EMI signals into a persistent DC offset, bypassing on-board filtering and causing stable measurement deviations. The authors verified the attack's consistency across 15 tactile sensors of different types on 10 sensor modules and 2 dexterous hands, and demonstrated real-world impact through three case studies: tactile grasping, slip detection, and material classification. For example, it could cause a domestic robot to exert excessive force. The work has been accepted to ACM CCS 2026.

    Warp: Structured Output-Space Adaptation for Frozen Robot Policies

    The authors propose Warp, a context-conditioned monotone bijective spline adapter that nonlinearly reshapes the sampled outputs of a frozen base policy while preserving per-dimension ordering. Across four ManiSkill tasks, Warp achieves the strongest recovery in a matched evolution-strategy adapter study; after switching to PPO, the ordering relationships vary by task. In a physical SO101 peg insertion task, Warp's success rate is comparable to a strong stochastic residual, with median time per successful cycle reduced by about 30%.

    RegimeVGGT: A Training-Free Acceleration Method for VGGT That Preserves Spatial Structure Layer by Layer

    RegimeVGGT proposes a training-free, layer-wise compression method that achieves a 6.7x speedup over the memory-optimized VGGT* with unchanged reconstruction quality. Through spectral analysis, probing, and causal analysis, the authors find that VGGT's shallow layers lack cross-view structure, its middle layers handle cross-view alignment, and its deep layers are redundant for dense geometry, but their cross-frame attention remains critical for pose.

    PS2-RL: A Provably Safe and Scalable Reinforcement Learning Framework

    The authors propose PS2-RL, a two-phase framework that uses a learned backup policy to forward-integrate the system dynamics and generate an implicit control-invariant set online, thereby avoiding the dimensionality-scaling problems caused by explicitly constructing control-invariant sets. In the first phase, the backup policy is trained with a safe-arrival value function to achieve safe recovery to a certified base set; in the second phase, an RL policy is trained end-to-end through a differentiable projection layer, strictly guaranteeing the safety induced by the backup policy. The framework does not restrict the underlying RL algorithm and can be integrated into existing training pipelines. It was evaluated on robot control tasks with state dimensions up to 10.

    RoboTryOn: Synthesizing Robot Dexterous Manipulation Demonstrations from Human Videos via Virtual Try-On

    RoboTryOn proposes treating human-to-robot translation as virtual try-on: it preserves the demonstrated motion, objects, and background, and only replaces the human with the target robot specified by a reference image. The method autoregressively converts keyframes and uses them to guide video synthesis, with motion conditioned on the human hand skeleton; it then uses an inverse dynamics model (IDM) with depth features to infer action labels from the synthesized videos for policy learning. Experiments show that policies trained only on synthetic data improve average success rate from 2% to 60% on new tasks, including dual-arm manipulation, and reach the level of policies taught by pure teleoperation at about one-third of the collection cost.

    Study: How inertia mismatch affects robot policy learning when robots are heavier than objects

    This paper investigates how inertia mismatch between a robotic arm and the objects it manipulates affects robot policy learning. Through controlled simulation experiments that vary robot and object masses, it finds that reinforcement learning succeeds across a broad range of mass combinations, while behavior cloning learns more reliable policies when a lighter robot manipulates a heavier object.

    Tactus: A tactile and pose-sensing glove for natural dexterous manipulation data collection

    The authors propose Tactus, a textile-integrated sensing glove that provides both capacitive tactile force sensing and IMU-fused pose tracking with a 1.5 mm fingertip stackup thickness, for collecting natural dexterous manipulation demonstration data. At 95% confidence, the glove's minimum detectable force is 0.59 N, 1.6–2.7 times lower than two commercial tactile glove baselines, with cross-subject consistency of 0.87; under the most severe manipulation occlusion, the relative error of fingertip keypoints is 11.0 mm.

    PriMoRetarget: Humanoid Motion Transfer via Prioritized Motion Retargeting

    The authors propose PriMoRetarget, a motion retargeting framework that replaces relative weight weighting with an explicit priority hierarchy, so that lower-priority updates are constrained to preserve higher-priority objectives. The method is evaluated on four datasets covering single-person motion, person-object manipulation, and person-person interaction; the generated motions better preserve task-relevant interactions and provide reference trajectories that are easier to track than those of commonly used retargeting methods.

    Low-cost 4-DoF arm RoArm-M2-S achieves vision-guided writing tool reorientation and color sorting

    The roughly $200 Waveshare RoArm-M2-S four-degree-of-freedom robotic arm, under a fixed overhead camera, uses a YOLO11n-OBB detector, an ArUco reference pose, and a color classifier to perform color sorting of writing utensils without a wrist rotation joint. For utensils deviating more than 45 degrees from the fixed approach direction, corrective sweeps bring them into a graspable pose within at most 4 attempts. In 196 single-utensil trials, 176 (89.8%) landed in the correct color bin; of the 20 failures, 19 were grasp slips or missed grasps and 1 was a color mislabel.

    Reverse to Advance: Learning Hard Manipulation Policies with Reversed Easy-Task Data to Cut Teleoperation Costs

    This paper proposes a teleoperation-cost-effective framework that uses temporally reversed trajectories from easy tasks as supervision signals for hard manipulation tasks, reducing manual demonstration collection. The framework has three parts: a closed-loop data collection pipeline, hierarchical data refinement based on kinematic priors and critic-guided advantage filtering, and iterative policy learning. In two simulation benchmarks and real-robot experiments, the method improved success rates on hard tasks compared with reversal-based and reinforcement-learning baselines, with higher data efficiency and more stable training.

    SDN: Improving VLA policy robustness at test time via selected diffusion noise

    The authors propose Selected Diffusion Noise (SDN), a training-free method that treats diffusion noise as a controllable degree of freedom to improve the test-time reliability of VLA policies. SDN samples multiple candidate action chunks and performs two-stage selection: it first filters by task-relevant visual grounding using a counterfactual negative set, then selects the kinematically most stable action chunk based on JerkRMS. In simulation and real-world experiments with three VLA policies, it achieved improvements of 8-10% and 18.33%, respectively.

    InDex: Adapting VLA models to dexterous manipulation via intent-conditioned fine-tuning

    The study proposes the InDex framework, which uses a normalized aperture signal derived from retargeted demonstrations to supervise a scalar grasp intent, adapting parallel-gripper VLA models to multi-fingered dexterous hands in two stages. Across four simulated tasks, InDex with π0.5 achieved 85.8% mean task success, a 35.5 percentage point improvement over the native policy, and reached 69.0% on new objects with similar geometry without fine-tuning. It was also effective across three VLA backbones and on a separately trained real-world policy, whose mean success rate rose from 71.0% to 83.0%.

    Learning Soft Robot Dynamics: An Uncertainty-Aware Active Exploration Framework

    The authors propose an uncertainty-aware active exploration framework that can autonomously learn task-agnostic, generalizable dynamics models for soft robots. The method was evaluated on three simulation platforms—a continuum arm, an articulated fish in fluid, and a musculoskeletal leg—as well as on a real pneumatically actuated continuum arm. Compared with random exploration and task-specific baselines, it achieves higher modeling accuracy and yields higher returns in zero-shot control on unseen tasks, while remaining robust under sensing noise, actuation delays, and material nonlinearities.

    MARLIN: Guiding Multi-Agent Reinforcement Learning with Language Negotiation

    MARLIN proposes a hybrid framework in which large language models guide policy learning by generating high-level action plans through inter-robot language negotiation before the reinforcement learning policy has learned effective behaviors, and it dynamically switches between reinforcement learning and language-model negotiation during training. The authors evaluated it on simulated and physical robots with local and remote language models; results show higher early-training performance than standard multi-agent reinforcement learning, with limited impact on final performance. The code is publicly available, and the paper was accepted to ROBIO2026.

    Fluidic Body: Controlling swarm robots as a fluid extension of the hand

    The authors propose the Fluidic Body system, which lets an operator change the properties of a virtual fluid between the hand and a swarm robot collective through hand movements, thereby adjusting swarm behavior: opening the hand makes the swarm soft and deformable so it can flow around obstacles, while clenching the fist makes the swarm hard and cohesive so it can aggregate into a single body to push objects.

    3D Rotation Representations: Mathematical Foundations and Comparative Analysis

    This paper systematically reviews multiple rotation representations of SO(3), including Euler angles, axis-angle vectors, quaternions, rotation matrices, exponential maps, and emerging continuous and probabilistic methods, and compares them across dimensions such as continuity, susceptibility to gimbal lock, computational efficiency, storage requirements, interpolation, and composition operations. Empirical results show that quaternions are advantageous due to their compactness and efficiency, while 6D continuous representations and matrix Fisher distributions offer greater advantages in continuity and uncertainty modeling.

    HALO: Humanoid Autonomy System Trained on Synthetic Simulation Data Achieves Zero-Shot Real-World Transfer

    The research team proposes HALO, a humanoid robot autonomy system that synthesizes vision-language-action data across roughly one thousand procedurally generated home scenes, eliminating reliance on teleoperation data collection. HALO learns skills including sitting on chairs, navigating to specified objects, stepping sideways through half-open doors, crouching and crawling under tables, and pushing boxes, and can combine them to complete long-horizon tasks. Without ever seeing real home scenes during training, HALO transfers zero-shot to the physical world, achieving a 91% success rate across 360 trials in six unmapped real-world environments.

    Why it matters: The paper presents a complete path from synthesizing vision-language-action data using procedurally generated home scenes to zero-shot transfer to real robots; its approach to data scaling is worth referencing.

    A study accepted to IEEE Telepresence 2026 had ROVs face controlled cross-currents in in-water experiments, conveying environmental information to operators through a soft vibrating haptic touchpad. Results showed that encountering an unforeseen cross-current significantly increased operators' physical and temporal demand, and haptic feedback mitigated these burdens and improved self-assessed performance, but also brought the highest mental demand and frustration; nevertheless, operators drove the ROV significantly faster under the haptic condition than under the current-information-only condition.
