The use of drones in agriculture is becoming more and more popular. The paper presents a novel approach to dis- tinguish between different field’s plowing techniques by means of an RGB-D sensor. The presented system can be easily integrated in commercially available Unmanned Aerial Vehicles (UAVs). In order to successfully classify the plowing techniques, two different measurement algorithms have been developed. Experimental tests show that the proposed methodology is able to provide a good classification of the field’s plowing depth

This work addresses the problem of semi-automatic inspection and navigation in confined environments. A system that overcomes many challenges at the state of the art is presented. It comprises a multirotor able to inspect an industrial combustion chamber thus working in a GPS-denied environment with poor lighting conditions, in the presence of magnetic and communication disturbances, iron dust and repetitive patterns on the structure walls. The presented system is able to pass through narrow entrances but still capable of acquiring high resolution images and to allow operators to perform inspection of the structures. Starting from the captured data, the system is able to provide a 3D reconstruction of the inspected environment for offline analysis.

This letter presents a novel wearable haptic controller (WHC) system suitable for teleoperation of demolition machines and robotic platforms. With regard to existing operator controller unit composed by passive joysticks, the WHC has been designed to provide force feedback to the user, hence improving the user perfor- mance during the teleoperation of different robotic platforms and the interaction with the environment on the remote construction sites. The haptic feedback is provided through two compact parallel kinematic (CPK) interfaces that will be presented within the paper. The CPK implements a novel variant of the Delta kinematics which allows minimizing the radial encumbrance while preserving same operational workspace. In addition, we propose a new interaction modality that provides users the feeling of directly maneuvering the end-effector of the demolition machine. Finally, the architec- ture of the proposed system is presented and the results of some preliminary evaluation tests are discussed. The experiments have been performed in simulated environments and on a real machine
