The UGVs are equipped with low cost Geiger-Müller counters whose measurements are simulated using Poisson statistics. Gaussian Process Regression (GPR) is used to generate a model of the radiation field that includes uncertainty estimates. In the current work, the UAVs do not have sensors and only act as carrier drones for the UGVs equipped with sensors. The UAVs leverage information-driven path planning where the metric for information is the uncertainty in the GPR model. This information metric is used to determine regions to deploy the UGVs. The UGVs cover their given region using Boustrophedon cellular decomposition. Monte Carlo studies show that UAV-UGV teams using information theoretic path planning (ITPP) are able to lower the model error significantly faster relative to control experiments with UGV-only mapping or with UAV-UGV teams performing random sampling (RS). The model error decays exponentially for the UAV-UGV teams but only linearly for the UGV-only teams. These results illustrate a potential system concept for UAV-UGV teams performing radiation mapping and provide baseline results quantifying potential performance improvements over systems employing only mobile ground sensors.","PeriodicalId":423263,"journal":{"name":"2021 IEEE International Symposium on Safety, Security, and Rescue Robotics (SSRR)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121875012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tracked vehicles, along with wheel-driven propulsion systems, are the preferred platform for Unmanned Ground Vehicles (UGVs) in poor terrain conditions. However, these robots have problems with cornering, turning maneuvers or rotation around the central axis. Depending on the coefficient of friction between the tracks and the ground, the total weight and center of mass tracked vehicles produce higher slip, purely accurate and reliable pose estimation. To improve the direction of motion and the prediction of the resulting track forces and odometry calculation for tracked vehicles, a tactile surface sensor was developed to provide improved odometry determination for different ground conditions. The integration of the measurement data of the pressure sensor and the use of an improved model to determine the contact points and to improve the odometry calculation are the main objectives of this work. This is achieved by calculating the centre of gravity of the two tracks separately, using the measurement data of the pressure sensor and the local coordinates $(x,y)$ of each of the measurement points. The sensor concept was tested and evaluated on different grounds and terrains. The system can be used as a predictive model for tracked vehicle traversability and to ensure a stable position when straight manipulation tasks must be performed on rough terrain.","PeriodicalId":423263,"journal":{"name":"2021 IEEE International Symposium on Safety, Security, and Rescue Robotics (SSRR)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134579223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each quadrotor is connected to the payload using a rigid link, where the joints to the payload are located on two perpendicular lines through the center of mass of the payload. The proposed solution includes an adaptive control scheme comprising several modules. Each module is responsible for controlling the motion of a specific subsystem of the entire payload-links-quadrotors system. Since an adaptive model-free control algorithm is utilized for tracking the desired set-points for each module, no information on the inertial parameters of the drones is required. The formation topology is achieved among the quadrotors by a geometry-based solution. Moreover, by utilizing a special linear Kalman filter for estimating the unit vectors along the connecting rigid links, the requirement for position and velocity estimation of the drones is revoked. Instead, the position and velocity of the payload must be estimated by using appropriate sensors. The solution is validated via numerical simulation of transporting a payload along a time-varying trajectory.","PeriodicalId":423263,"journal":{"name":"2021 IEEE International Symposium on Safety, Security, and Rescue Robotics (SSRR)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116858216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As with any other online data sharing technique, data integrity is a concern, but it has not yet been addressed in the multi-robot information sampling literature. In this paper, we study how to secure the information being shared among the robots in such a multi-robot network against integrity attacks and what is the cost of integrating such security techniques. To this end, we propose a Blockchain-based information sharing protocol that helps the robots reject fake data injection by a malicious entity. On the other hand, optimal information sampling is a compute-intensive technique and so are the popular Blockchain-based consensus protocols. Therefore, we also study the impact of adding such a security protocol on the execution time of the sampling algorithm, which in turn effects the energy spent by the robots. Results show that our proposed technique is effective against such data tampering attempts while the effect of the added computation varies largely on the consensus protocol used.","PeriodicalId":423263,"journal":{"name":"2021 IEEE International Symposium on Safety, Security, and Rescue Robotics (SSRR)","volume":"55 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127123258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We describe how such a holistic approach is implemented by the partners in the cooperative project A-DRZ for the establishment of the German Rescue Robotics Center (DRZ). The A-DRZ approach addresses important requirements identified by first responders: adaptation of operational capabilities of robotic platforms; robust network connectivity; autonomous assistance functions facilitating robot control; improving situation awareness for strategic and tactical mission planning; integration of human-robot teams in the first responders' mission command structure.

As multi-robot systems become more frequently used for disaster response due to the inherent dangerous environments, these systems must be controlled in way that balances the accomplishment of their mission with interaction with neighboring teams. In this paper, we address this problem by examining the balance of mission and comprehensibility. By mission, we refer to the overall task of the multi-robot system, which in a disaster response scenario is often searching an area and communicating results back to rescuers. By comprehensibility, we refer to a multi-robot system arranging itself in a way that a neighboring observer can understand what roles its members play, and react accordingly. When mission and comprehensibility are properly balanced, multi-robot teams will be more effective at working alongside one another. We propose a system of control laws for two robot roles, hubs and sensors, which provide communication and sensing, respectively. We propose additional control laws to maintain an understandable formation. Through extensive simulation of a variety of multi-robot system sizes and formations, we examine the effect of balancing mission and comprehensibility on concrete metrics for sensor coverage and role understanding.","PeriodicalId":423263,"journal":{"name":"2021 IEEE International Symposium on Safety, Security, and Rescue Robotics (SSRR)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125160775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
