Ample research is conducted on ICT, automation and robotics in agriculture and related environmental issues. ICT and robotics innovations are rapidly emerging and have the ability to revolutionize future farming through their major impacts on productivity and profitability. Unfortunately human and financial resources and efforts are fragmented and limited. this led to the creation of the ICT-AGRI ERA-NET that provides a central structured framework. Its main objective is to strengthen and coordinate European research regarding ICT and robotics in agriculture. Besides the creation of the Meta Knowledge Base (MKB), a common European research agenda will be developed and common research calls are launched. the Meta Knowledge Base (http://***) is attempting to map all relevant research and development within the selected research area. To accomplish the mapping, two types of information are collected: research profiles and research postings. To organize the postings, a three-dimensional task technology oriented framework was designed. the results indicated that the three axes: task, technology and scope seemed insufficient to describe the whole research area. therefore, an improved framework was developed. By extending the task-technology oriented framework with a process-control information system, a useful framework was designed.

In this paper we address the problem of dot painting on a wall by a quadrotor Micro Air Vehicle (MAV), using on-board low cost sensors (monocular camera and IMU) for localization. A method is proposed to cope with uncertainties on the initial positioning of the MAV with respect to the wall and to deal with walls composed of multiple segments. this method is based on an online estimation algorithm that makes use of information of physical contacts detected by the drone during the flight to improve the positioning accuracy of the painted dots. Simulation results are presented to assess quantitatively the efficiency of the proposed approaches.

this paper describes our efforts and plans to develop a Virtual Laboratory for the education in robotics and automation. these efforts are characterized by the need of blending R&A subjects into a traditional Computer Science curriculum, thus forcing a specific selection of development topics. In this context, the robotics Laboratory must provide basic as well as advanced experiments, to address the needs of students at different education levels. In this paper, we present the development of three main applications, to support control Systems and robotics classes, as well as thesis and dissertation research. Of particular interest is the effort in the area of teleoperation, preliminary to the opening, next year, of a new curriculum on Medical informatics, in which Computer Assisted Surgery will play an important role.

the visual alignment robot system for display and semiconductor fabrication process largely consists of multiaxes precision stage and vision peripherals. One of the central issues in a display or semiconductor mass production line is how to reduce the overall tact time by making a progress in the alignment technology between the mask and panel. In this paper, we suggest the kinematics of the 4PPR parallel alignment mechanism with four limbs unlike usual three limb cases and an effective pattern recognition algorithm for alignment mark recognition. the inverse kinematic solution determines the moving distances of joint actuators for an identified mask-panel misalignment. Also, the proposed alignment mark detection method enables considerable reduction in computation time compared with well-known pattern matching algorithms.

Computer vision is an advanced technology and is widely used in aspects such as IoT, agricultural robotics and machine learning. the detection and extraction of plants are the primary tasks of this application. this article shows several index-based colour analysis computer vision methods and relative improvement to extract the plants from backgrounds which contain complex information. the sample images are from the Plant Phenotyping Dataset which contains arabidopsis as desired plants and interference information (metal, moss, white table, etc.). A comparison of the three methods is provided. these methods are Excess Green Index (ExG), Excess Red Index (ExR), and the combination of ExG and ExR (ExG-ExR). Meanwhile, a mask to remove the non-green object (BR mask), Gaussian filter, and erosion operation are added as an improvement to remove the remains. Withthe evaluation method such as Intersection over Union (IoU) and Sorensen-Dice Similarity Coefficient (DSC), the combination of ExG-ExR, BR mask, Gaussian filter, and erosion shows the best performance with IoU and DSC rate 0.8818 and 0.9368 respectively. However, one setback is that green information like moss is hard to be distinguished from desired plants withthese methods. this problem will be researched in the future.

Nowadays, robotics is increasing its importance for the marine environment in our society. It allows to perform surveillance and data sampling tasks reducing the current cost of these tasks. this paper presents the design of a prototype of an Autonomous Surface Vessel (ASV) based on catamaran shape. It uses the screw theory for the propulsion system, which provides high manoeuvrability to the vessel. Furthermore, the parts of the ASV are designed to be printed by a RepRap 3D printer. this gives flexibility to check the performance of the vessel. Also the software control scheme of the vessel is presented.

this paper presents the design of Impedance control to a redundantly actuated Parallel Kinematic Manipulator. the proposed control is based on treating each limb as a single system and their connection through the internal interaction forces. the controller introduces a stiffness and damping matrices that decouples the dynamic behaviour of the robot. control allocation of torques is applied through an optimization that promotes even distribution of torques over actuators. Simulations showed a good compliance behaviour in low frequencies.

the paper describes the main conclusions issued from three years of development, of which approximately eighteen months of observations, of an autonomous social robot interacting with children and adults in the Pediatrics ward of an Oncological hospital. After this long period of trials and continuous interaction, the integration of the robot in that particular social environment can be considered highly successful. the results taken from all the long run experiments yield valuable lessons in what relates social acceptance and user experience to be considered in the case of robot deployment at institutions or even at households. these are detailed in the paper.
