The modules will benefit those working in various sectors, for example, in medical, manufacturing and defence industry. Participants will gain in-depth knowledge in areas like understanding autonomous behaviour types in robotics, robotics sensory operations, understanding robotics mobility, and robotic path planning and fuzzy behaviours in robotics.

This is a course designed to help engineers and scientists to acquire the skills of building Mobile robotics and autonomous vehicles with commonly available components and methods. New application domains like geological survey cover vast areas exceeding endurances of most modern aerial platforms and the available path planners do not address coverage of such areas. This paper presents an approach for generating coverage paths for large-scale aerial mapping. The planner applies voronoi partitioning to decompose large areas into manageable cells. Then generates boustrophedon paths to cover each cell.

The proposed planner is incorporated into Mission Planner. Software in the loop simulation results have ascertained the feasibility and completeness of the generated paths, even with multiple micro aerial platforms. Collective motion is one of the most fascinating phenomena observed in nature.

In the last decade, it aroused so much attention in physics, control and robotics fields. In particular, many studies have been done in swarm robotics related to collective motion, also called flocking. In most of these studies, robots use orientation and proximity of their neighbors to achieve collective motion.

In such an approach, one of the biggest problems is to measure orientation information using on-board sensors. In most of the studies, this information is either simulated or implemented using communication. In this paper, we implemented a fully autonomous coordinated motion without alignment using very simple Mona robots. We modified the method and added the capability to enable the swarm to move toward a desired direction and rotate about an arbitrary point. We tested our approach in different settings using Matlab and Webots. Despite the great progress in quadrupedal robotics during the last decade, selecting good contacts footholds in highly uneven and cluttered environments still remains an open challenge.

This paper builds upon a state-of-the-art approach, already successfully used for humanoid robots, and applies it to our robotic platform; the quadruped robot ANYmal. The proposed algorithm decouples the problem into two subproblems: first a guide trajectory for the robot is generated, then contacts are created along this trajectory. Both subproblems rely on approximations and heuristics that need to be tuned.

Autonomy & Robotics

The main contribution of this work is to explain how this algorithm has been retuned to work with ANYmal and to show the relevance of the approach with a variety of tests in realistic dynamic simulations. This paper addresses multi-robot multi-goal motion planning with temporal and resources constraints. It solves the vehicle routing problem for mobile robots that operate according to their system dynamics, and which have to visit a number of waypoints scattered in a two-dimensional map environment with obstacles, while satisfying time window and capacity constraints.

Macro actions enable the vehicles to run in real-time with best actions being distributed to the individual controllers. We analyze how the simulation is affected by varying parameters such as the number of vehicles. Musical instrument education has typically faced challenges in providing students with a cost-efficient and long-term solution for personalised tutoring. To address these challenges, we propose a musical instrument tutor robot for students learning the recorder, called instruMentor.

Equipped with robotic hands and a multimodal interface, the robot interacts with users by playing the recorder and demonstrating in real-time the proper handling of the instrument.

Towards Autonomous Robotic Systems

A pilot study was conducted to investigate the effectiveness of a robot tutor for instrument learning. Experimental results suggest that instruMentor is successful at teaching the recorder and is positively appreciated by users, showing promise for the future coupling of music tutoring and social robots.

In this paper we describe how a generic interoperability telerobotics protocol can be applied for master-slave robotic systems operating in position-position, position-speed and hybrid control modes. The interoperability protocol allows robust and efficient data exchange for teleoperation systems, however it was not shown how it can fit switching position and rate control modes. Here we propose the general framework of hybrid position and rate control modes with interoperability protocol.

In this paper we present a fully autonomous and intrinsically motivated robot usable for HRI experiments. We argue that an intrinsically motivated approach based on the Predictive Information formalism, like the one presented here, could provide us with a pathway towards autonomous robot behaviour generation, that is capable of producing behaviour interesting enough for sustaining the interaction with humans and without the need for a human operator in the loop. We present a possible reactive baseline behaviour for comparison for future research. Participants perceive the baseline and the adaptive, intrinsically motivated behaviour differently.

In our exploratory study we see evidence that participants perceive an intrinsically motivated robot as less intelligent than the reactive baseline behaviour. We argue that is mostly due to the high adaptation rate chosen and the design of the environment. However, we also see that the adaptive robot is perceived as more warm, a factor which carries more weight in interpersonal interaction than competence. We present the design of a one-degree-of-freedom ankle actuation platform for human-robot interaction.

The platform is actuated with a DC motor through a capstan drive mechanism. The results for platform dynamics identification including friction characterisation are presented. Control experiments demonstrate that a linear regulator with gravity compensation can be used to control the inclination of the platform efficiently. Identifying the roles and the specific social behaviours that evoke human trust towards robots is key for user acceptance. Specially, while performing tasks in the real world, such as navigation or guidance, the predictability of robot motion and predictions of user intentions facilitate interaction.

We present a user study in which a humanoid-robot guided participants around a human populated environment, avoiding collisions while following a socially acceptable trajectory. We investigated which behaviours performed by a humanoid robot during a guidance task exhibited better social acceptance by people, and how robot behaviours influence their trust in a robot to safely complete a guiding task.

  5. We concluded that in general, people prefer and trust a robot that exhibits social behaviours such as talking and maintaining an appropriate safe distance from obstacles. The development of autonomous robots for agriculture depends on a successful approach to recognize user needs as well as datasets reflecting the characteristics of the domain. Available datasets for 3D Action Recognition generally feature controlled lighting and framing while recording subjects from the front.

    They mostly reflect good recording conditions and therefore fail to account for the highly variable conditions the robot would have to work with in the field, e. Existing work on Intention Recognition mostly labels plans or actions as intentions, but neither of those fully capture the extend of human intent. In this work, we argue for a holistic view on human Intention Recognition and propose a set of recording conditions, gestures and behaviors that better reflect the environment and conditions an agricultural robot might find itself in. We demonstrate the utility of the dataset by means of evaluating two human detection methods: bounding boxes and skeleton extraction.

    With the rise of Virtual Reality VR applications it is interesting to see how immersion can be improved, especially by providing haptic feedback on the user hands, using affordable technologies.

    Autonomous Robots

    Indeed, while several commercial products exist that can be used as input devices i. We describe here the design and realization of an affordable data glove to provide vibrotactile feedback to human users using small vibrating motors, and we report preliminary user studies to prove its effectiveness; interestingly, combined with a commercially available optical tracker i. Leap Motion to be used as input device, the data glove can be used in a wide range of Virtual Reality and Telerobotics applications. User studies include i rendering a feedback to multiple fingers at the same time, and recording how many stimuli the users could correctly differentiate, and ii simulating the stiffness of a virtual object, and testing through a Just Noticeable Difference JND experiment whether participants could differentiate two objects chosen among 20 pairs of objects with varying stiffness.

    In our training simulator, the user is fully immersed in a virtual reality VR environment. A typical hospital bedside scenario was recreated, and the users can see their own body and the patient increase immersion. The main idea behind this work is for the user to associate the heart and lung sounds, as heard through the stethoscope with the corresponding health-related problems.

    About this book

    Several sound parameters including the volume, give information about the type and severity of the disease. Our simulator can reproduce sounds belonging to the heart and lungs. Through the proposed VR-based training, the medical student ideally will learn to relate sounds to illnesses in a realistic setting, accelerating the learning process.

    Additional information

    This paper provides a comprehensive note on screw displacement. The geometric approach provides better physical insights and the exponential method demonstrates elegant and rigours mathematical perception. Application of the screw displacement is illustrated by the development of a RSCR-mechanism based landing gear. Here we describe a simple modular 3D-printed design for an inverted pendulum system that is driven using a stepper motor operated by a microcontroller.

    The design consists of a stainless-steel pole that acts as the pendulum, which is pivoted at one end and attached to a cart. Although in its inverted configuration the pendulum is unstable without suitable control, if the cart travels backwards and forwards appropriately it is possible to balance the pole and keep it upright. The pendulum is intended for use as a research and teaching tool in the fields of control engineering and human sensori-motor control.

    We demonstrate operation of the design by implementing an observer-based state feedback controller, with augmented positional state of the cart and integral action, that can balance the pole in its unstable configuration and also maintains the cart at its starting position. When the controller is running, the pendulum can resist small disturbances to the pole, and it is possible to balance objects on its endpoint. GDA is non-symbolic, preserves simple formulation, and is convenient for numerical implementation.

    GDA-based algorithms are deduced for efficient calculation of various dynamic quantities including 1 joint space inertia matrix JSIM 2 Coriolis matrix 3 centrifugal matrix 4 and the time derivative of JSIM.
