abstract={Vision-based deep learning perception fulfills a paramount role in robotics, facilitating solutions to many challenging scenarios, such as acrobatic maneuvers of autonomous unmanned aerial vehicles (UAVs) and robot-assisted high-precision surgery. Control-oriented end-to-end perception approaches, which directly output control variables for the robot, commonly take advantage of the robot's state estimation as an auxiliary input. When intermediate outputs are estimated and fed to a lower-level controller, i.e., mediated approaches, the robot's state is commonly used as an input only for egocentric tasks, which estimate physical properties of the robot itself. In this work, we propose to apply a similar approach for the first time -- to the best of our knowledge -- to non-egocentric mediated tasks, where the estimated outputs refer to an external subject. We prove how our general methodology improves the regression performance of deep convolutional neural networks (CNNs) on a broad class of non-egocentric 3D pose estimation problems, with minimal computational cost. By analyzing three highly-different use cases, spanning from grasping with a robotic arm to following a human subject with a pocket-sized UAV, our results consistently improve the R{\$}{\$}^{\{}2{\}}{\$}{\$}regression metric, up to +0.51, compared to their stateless baselines. Finally, we validate the in-field performance of a closed-loop autonomous cm-scale UAV on the human pose estimation task. Our results show a significant reduction, i.e., 24{\%} on average, on the mean absolute error of our stateful CNN, compared to a State-of-the-Art stateless counterpart.},

abstract = {Palm-sized nano-drones are an appealing class of edge nodes, but their limited computational resources prevent run-ning large deep-learning models onboard. Adopting an edge-fog computational paradigm, we can offload part of the com-putation to the fog; however, this poses security concerns if the fog node, or the communication link, can not be trust. To tackle this concern, we propose a novel distributed edge-fog execution scheme that validates fog computation by re-dundantly executing a random subnetwork aboard our nano-drone. Compared to a State-of-the-Art visual pose estima-tion network that entirely runs onboard, a larger network ex-ecuted in a distributed way improves the R^2 score by +0.19; in case of attack, our approach detects it within 2 s with 95\% probability.},
