A special variant of Distributed Model Predictive Control (DMPC) has emerged as a promising approach for the safe management of these swarms by combining the scalability of distributed computation with dynamic swarm motion control. In this DMPC method, multiple agents solve local optimization problems with coupled anti-collision constraints, periodically exchanging their solutions. Despite its potential, existing methodologies using this DMPC variant have yet to be deployed on distributed hardware that fully utilize true distributed computation and wireless communication. This is primarily due to the lack of a communication system tailored to meet the unique requirements of mobile swarms and an architecture that supports distributed computation while adhering to the payload constraints of UAVs. We present DMPC-Swarm, a new swarm control methodology that integrates an efficient, stateless low-power wireless communication protocol with a novel DMPC algorithm that provably avoids UAV collisions even under message loss. By utilizing event-triggered and distributed off-board computing, DMPC-Swarm supports nano UAVs, allowing them to benefit from additional computational resources while retaining scalability and fault tolerance. In a detailed theoretical analysis, we prove that DMPC-Swarm guarantees collision avoidance under realistic conditions, including communication delays and message loss. Finally, we present DMPC-Swarm’s implementation on a swarm of up to 16 nano-quadcopters, demonstrating the first realization of these DMPC variants with computation distributed on multiple physical devices interconnected by a real wireless mesh networks.

In recent years, some related works have attempted to utilize semantic information or geometric constraints between consecutive frames to reject dynamic objects as outliers. However, challenges persist, including poor real-time performance, heavy reliance on meticulously annotated datasets, and susceptibility to misclassifying static points as dynamic. This paper presents a novel dynamic LiDAR SLAM framework called DynaLOAM, in which a complementary dynamic interference suppression scheme is exploited. For accurate relative pose estimation, a lightweight detector is proposed to rapidly respond to pre-defined dynamic object classes in the LiDAR FOV and eliminate correspondences from dynamic landmarks. Then, an online submap cleaning method based on visibility and clustering is proposed for real-time dynamic object removal in submap, which is further utilized for pose optimization and global static map construction. By integrating the complementary characteristics of prior appearance detection and online visibility check, DynaLOAM can finally achieve accurate pose estimation and static map construction in dynamic environments. Extensive experiments are conducted on the KITTI dataset and three real scenarios. The results show that our approach achieves promising performance compared to state-of-the-art methods.

This paper presents a unified framework, <span>mEclares</span>, that addresses both challenges through adaptive ergodic search and energy-aware scheduling in multi-robot systems. Our contributions are two-fold: (1) we model real-world variability using stochastic spatiotemporal environments, where the underlying information evolves continuously over space and time under process noise. To guide exploration, we construct a target information spatial distribution (TISD) based on clarity, a metric that captures the decay of information in the absence of observations and highlights regions of high uncertainty; and (2) we introduce <span>Robust-meSch</span> ( <span>RmeSch</span> ), an online scheduling method that enables persistent operation by coordinating rechargeable robots sharing a single mobile charging station. Unlike prior work, our approach avoids reliance on preplanned schedules, static or dedicated charging stations, and simplified robot dynamics. Instead, the scheduler supports general nonlinear models, accounts for uncertainty in the estimated position of the charging station, and handles central node failures. The proposed framework is validated through real-world hardware experiments, and feasibility guarantees are provided under specific assumptions.

This work presents a Voronoi-based coverage control approach to the multi-resource allocation problem, and considers a heterogeneous team comprising robots with different resource types and capacities. The team must supply resources to multiple demand locations. Demand of resources may change over time, and fluctuate in overall demand, which is represented over the environment as a time-varying density function. From the demand density, robots minimize their respective locational cost, adapting and moving to areas of higher demand. Robots must adhere to supply constraints and replenish resources over time to ensure persistent resource coverage. This paper therefore investigates how to enable persistent deployments, wherein robots must continually alternate between serving demand or replenishing resources. We explore four algorithms for resource replenishment, which vary in communication, forecasting, and information assumptions. Simulations and hardware experiments demonstrate a need-based auction algorithm, which aims to minimize service blackouts, produces the best performance for a heterogeneous team.

But how do humans convey what they want the robot to do? Existing methods largely rely on humans physically guiding the robot arm throughout their intended task. Unfortunately — as we scale up the amount of data — physical guidance becomes prohibitively burdensome. Not only do humans need to operate robot hardware but also modify the environment (e.g., moving and resetting objects) to provide multiple task examples. In this work we propose L2D2, a sketching interface and imitation learning algorithm where humans can provide demonstrations by <i>drawing</i> the task. L2D2 starts with a single image of the robot arm and its workspace. Using a tablet, users draw and label trajectories on this image to illustrate how the robot should act. To collect new and diverse demonstrations, we no longer need the human to physically reset the workspace; instead, L2D2 leverages vision-language segmentation to autonomously vary object locations and generate synthetic images for the human to draw upon. We recognize that drawing trajectories is not as information-rich as physically demonstrating the task. Drawings are 2-dimensional and do not capture how the robot’s actions affect its environment. To address these fundamental challenges the next stage of L2D2 grounds the human’s static, 2D drawings in our dynamic, 3D world by leveraging a small set of physical demonstrations. Our experiments and user study suggest that L2D2 enables humans to provide more demonstrations with less time and effort than traditional approaches, and users prefer drawings over physical manipulation. When compared to other drawing-based approaches, we find that L2D2 learns more performant robot policies, requires a smaller dataset, and can generalize to longer-horizon tasks.

However, achieving precise and efficient transitions across multiple moving UGVs without prior knowledge of their trajectories remains highly challenging. This paper proposes COVER, a cross-vehicle transition framework for quadrotor control in AGC scenarios. In COVER, the UAV is directly controlled in UGVs’ body frames as non-inertial frames, thus eliminating all dependencies in the world frame. Each transition process is divided into three stages: the initial stage, transition stage, and final stage, with pre-set stage transition points and stage-varying system states. Then, an optimal reference trajectory is generated at each stage by solving a non-linear programming (NLP) problem. The effect of the target UGV’s rotation on the initial relative velocity is eliminated to obtain a dynamically feasible and smooth transition reference trajectory. Finally, we design a stage-adaptive model predictive control (SAMPC) method, proposing a novel MPC position reference mode to avoid indirect routes at the transition stage. The SAMPC method effectively mitigates the flight instability caused by reference frame transition and eliminates the effect of reference frame rotation at the transition stage. And it can flexibly adapt to accurate requirements at the final stage by switching position reference mode and adjusting cost weights. Simulation benchmarks and extensive real-world experiments validate that our approach can achieve smooth, short-distance, and accurate cross-vehicle operations.</p></div>","PeriodicalId":55409,"journal":{"name":"Autonomous Robots","volume":"49 3","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144934659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
