Special Issue Information

Dear Colleagues,

This Special Issue (SI) aims to present scholarly papers addressing efficient robotic object perception problems from the perspective of AI for sensor-based perception, which leverages artificial intelligence techniques to enable robots to interpret and understand their surroundings through diverse sensors, mimicking how humans integrate multi-sensory inputs to navigate and interact with the world. This approach is critical for robotic systems, as it allows them to perceive objects, environments, and tasks dynamically, adapting to new scenarios with the intelligence to process, learn from, and act on sensor data. A key question arises: “how can AI empower sensor-based perception to enhance robotic capabilities?” To explore this, we invite scientists, researchers, robotic specialists, and academics to share their insights into advancing AI techniques that elevate sensor-driven perception. What role does AI play in fusing data from visual, auditory, tactile, or LiDAR sensors for more robust perception? How can AI models be optimized to handle noisy, incomplete, or real-time sensor inputs? Can AI enable robots to learn from sensor data incrementally, improving their perception over time—similarly to how humans refine their understanding through experience? 

Overall, this Special Issue focuses on AI-driven solutions for sensor-based robotic perception tasks, such as object classification, object detection, semantic segmentation, robot navigation, SLAM, and many others. The topics of interest include (but are not limited to) the following areas:

  • AI models for multi-sensor data fusion (e.g., vision, audio, touch, and LiDAR);
  • Deep learning architectures optimized for real-time sensor processing;
  • Few-/zero-shot learning for sensor-based perception;
  • Embodied AI for sensor-driven robotic interaction;
  • Federated learning for collaborative sensor data analysis;
  • Meta-learning to enable rapid adaptation to new sensor inputs;
  • Self-supervised learning from unlabeled sensor data;
  • Domain adaptation for robust perception across varying sensor conditions;
  • Semi-supervised and unsupervised learning for sensor data interpretation;
  • Lifelong/continual learning to refine sensor-based perception over time.

This study aims to enhance the precision of humanoid robots in imitating complex human “walking–grasping” coordinated movements. Addressing limitations in sample efficiency and reward function design in Generative Adversarial Imitation Learning (GAIL), we propose the Similarity Reward-Augmented Generative Adversarial Imitation Learning (SRA-GAIL) framework. The method integrates plantar thin-film resistive pressure sensors to measure the real-time pressure distribution at four key points on both feet, combined with roll/pitch angle data acquired from JY901S inertial measurement units (IMUs). A Lagrangian constraint optimization strategy is employed to achieve gait stability control based on the zero moment point (ZMP). Simultaneously, a visual similarity evaluation module is established using human demonstration trajectories captured by a Logitech C920E camera, augmented by grip force feedback from flexible thin-film pressure sensors on the hands. This enables the design of a multimodal sensor-fused similarity reward function. By incorporating Lagrangian constraint optimization and a maximum entropy reinforcement learning framework, Similarity Reward-Augmented Generative Adversarial Imitation Learning synchronously optimizes gait stability control—guided by zero moment point (ZMP) and roll/pitch data—and vision-based trajectory similarity evaluation. These components address motion stability constraints and trajectory similarity metrics, respectively, generating biomechanically plausible gait strategies. A spatiotemporal attention mechanism parses human motion trajectory features to drive the end-effector for high-precision trajectory tracking. To validate the proposed method, an imitation learning experimental system was constructed on a physical XIAOLI humanoid robot platform, integrating inertial measurement units (IMUs), plantar pressure sensors, and a vision system. Quantitative evaluations were conducted across multiple dimensions, including robot platform analysis, walking stability, object grasping success rates, and end-effector trajectory similarity. The results demonstrate that, compared to Generative Adversarial Imitation Learning (GAIL) and behavioral cloning, Similarity Reward-Augmented Generative Adversarial Imitation Learning achieves a stable object grasping success rate of 93.7% in complex environments, with a 23.8% improvement in sample efficiency. The method maintains a 96.5% compliance rate for zero moment point (ZMP) trajectories within the support polygon, significantly outperforming baseline approaches. This effectively addresses the bottleneck in robot policies adapting to dynamic changes in real-world environments. Full article
