Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit contributions to the Special Issue entitled “Air–Ground Integrated Perception and Cooperative Control for UAVs and UGVs” in Drones.

With the rapid development of intelligent transportation and autonomous systems, unmanned aerial vehicles (UAVs) and unmanned ground vehicles (UGVs) have become key platforms for perception, monitoring, and cooperative control. UAVs provide flexible, wide-area, and long-range sensing and delivery capabilities, whereas UGVs enable accurate ground-level interaction and autonomous task execution. Emerging applications increasingly involve multi-UGV cooperative control and UAV-based long-range perception and delivery, which introduce new challenges in coordination, scalability, and system robustness.

The increasing complexity of real-world applications, such as urban traffic management and emergency response, highlights the need for integrated air–ground perception, cooperative control, and effective coordination among multiple UGVs, as well as robust UAV-based sensing and delivery control. Despite recent advances in artificial intelligence and communication technologies, significant challenges remain in scalable multi-agent coordination, communication-aware control, cross-modal perception consistency, and especially in air–ground collaboration.

The aim of this Special Issue is to bring together high-quality research that advances theories, algorithms, and applications related to Air–Ground Integrated Perception and Cooperative Control for UAVs and UGVs. It also encompasses multi-UGV cooperative control and UAV-enabled perception and delivery within unified autonomous system frameworks.

This Special Issue seeks contributions addressing the following themes, including but not limited to:

  • UAV aerial perception and delivery control;
  • UGV motion planning and multi-vehicle cooperative control;
  • Air–ground integrated perception and information fusion;
  • Cooperative control of heterogeneous UAV–UGV systems;
  • Communication-aware perception and control in unmanned autonomous Systems;
  • Edge–cloud intelligence for UAV–UGV collaborative systems;
  • Foundation models and large-scale simulation for air–ground intelligence.

We look forward to receiving your original research articles and reviews.

Deploying unmanned aerial vehicles (UAVs) cooperatively with legged robots for disaster response and inspection requires autonomous docking on miniature walking platforms. This study addresses the problem of landing a foldable quadrotor onto the back of a trotting wheel-legged robot (300×180 mm) and subsequently taking off while carrying it as a payload. Four tightly coupled challenges distinguish this task from conventional mobile-platform landing: (i) an extremely small landing surface, (ii) gait-induced periodic vibrations at 2.5 Hz, (iii) continuous platform translation at 0.30.8 m/s, and (iv) surface docking that requires simultaneous position and attitude matching rather than mere point tracking. The proposed framework comprises four components: (1) a novel single-servo crank-rocker folding mechanism that reduces the folded body footprint by 48.5% and the maximum linear dimension from 590 mm to 309 mm (↓47.6%) compared with the prior dual-servo design; (2) a staged Continuous Fast Nonsingular Terminal Sliding Mode (CFNTSM) controller combined with a Gait-Frequency-Aware Finite-time Extended Observer (GFA-FEO); (3) a Feature-wise Linear Modulation Soft Actor-Critic (FiLM-SAC) residual reinforcement-learning policy conditioned on physical states and mission phase, with an adaptive trust weight λ(t); and (4) a payload-adaptive takeoff strategy with parameter hot-switching to handle the twofold mass increase. Extensive Monte Carlo simulations and ablation studies across three experiment groups demonstrate that the proposed hierarchical framework achieves sub-centimetre (<10 mm) position accuracy and <3° attitude matching on a walking platform. Quantitatively, the full method reduces docking RMSE by 42% relative to the model-based CFNTSM + GFA-FEO controller without residual RL (4.2 vs. 7.2 mm) and reduces post-lock takeoff RMSE by 63% through FEO hot-switching (16.2 vs. 44.2 mm).

In persistent patrol and online task discovery in environments with obstacles, unmanned aerial vehicle (UAV) swarms are constrained by limited battery capacity and frequent recharging disrupts patrol continuity. In comparison, unmanned ground vehicle (UGV) fleets have higher endurance and payload capacity and can serve as mobile charging platforms while executing ground-service tasks. In such collaborative scenarios, UAVs patrol along a coverage path and discover tasks online, whereas UGVs execute discovered ground tasks and provide mobile charging support. To cope with rendezvous uncertainty due to obstacle-induced detours and inefficient usage of UGV time during charging, this study proposes an energy-constrained UAV-UGV coordination framework based on adaptive anticipatory rendezvous and time-window scheduling. In particular, the adaptive anticipatory rendezvous module handles anticipatory rendezvous planning, while the time-window scheduling module models the post-rendezvous charging stage as a schedulable time window for opportunistic ground-task insertion. Simulations demonstrate that the proposed framework consistently reduces system energy consumption, completion time, and the number of emergency landings compared with three representative baselines. Moreover, a UAV-UGV prototype with AprilTag-based visual landing and post-landing mechanical correction is developed to validate the engineering feasibility of the key closed-loop process.
