AEROCROS: AErial RObotic system for inspection by Contact of bridges and ROad Structures
The main objective of AEROCROS was the development of an aerial robotic system with a compliant, multilink manipulator arm for inspection by contact of bridges and road structures while it is flying, with a sensing module located at the end of the arm. The tests to assess the condition of cracks and rebars in reinforced concrete bridges need that a sensing module (i.e. ultrasonic) be in contact with the structure for a given amount of time to take the measurements.
Presently, experienced inspectors need a hands-on access to bridge components forperforming the tests, which is dangerous and tiring for the inspectors, can be very expensive and interferes with the road traffic. The application of ground robots does not solve the problem, since it interferes with the traffic and has problems reaching some bridge areas for inspection.
AEROCROS has developed several multirotor-based aerial robots. One of them has a specialized multi-link manipulator arm for inspection by contact of bridges and road structures. The arm is located in the upper part of the aerial robot, since many of the inspection tasks requiring contact in bridges have to be done from the underside. This configuration has never been tried before, and present many control and stability challenges. Furthermore, in order to maintain the contact of the sensing module with the structure, a compliant arm with compliant actuators will be developed, so that its elastic elements can absorb the perturbations and oscillations of the aerial robot while flying outdoors. The integrated, coupled controllers for the aerial platform and the compliant arm have also been developed in the project.
Another objective of the project was the development of the localization and mapping system needed to provide accurate relative positioning to compensate for the lack of reliable satellite positioning system under the bridge, and to guide the inspection.
The AEROCROS project has been demonstrated in several bridges at Seville Engineering School, Algodonales (Cádiz), Grazalema (Cádiz) and Strymonas (Grecia).
MULTICOP: autonomous MULTI-aerial systems for COoperative maneuvers with Physical interaction
Funded by: Fondos FEDER. Junta de Andalucia.
MULTICOP considers cooperative teams of UAVs that have to navigate together to perform some tasks jointly, involving physical interaction with the environment. In particular, the project focuses on the problem of autonomous transport of goods. The motivating application for MULTICOP is the so-called drone delivery, where logistics can be enhanced with UAVs that transport and deliver goods. Nonetheless, this cooperative transport could also be useful for other applications such as search and rescue. The main objective of MULTICOP is to reduce the existing technological gap for autonomous transport of goods with multi-UAV teams. This will be done by advancing on new methods for multi-UAV cooperation in large-scale missions, planning and scheduling tasks taking into account the limited flying time for UAVs and other temporal constraints. Also, novel motion planning and control algorithms will be researched to execute joint maneuvers safely between several UAVs. For that, UAVs with grippers onboard will be considered for cooperative transport, and the influences between the different UAVs transporting will be studied. In MULTICOP, the main focus is on developing novel techniques for future applications, instead of building a complete prototype. Nonetheless, extensive simulations on a realistic framework will be performed to validate the methods. Moreover, field experiments will be carried out to assess the validity of some of the advances as a proof of concept.

INSPECTOR: INdustrial inSPECtion and mainTenance of complex OR unattended facilities
Funded under CDTI – Programa CIEN 2018
INSPEQ-UAVs PARA INSPECCIÓN DE INTERIOR DE EQUIPOS; INSPESOL-INSPECCIÓN DE PLANTAS SOLARES CON MÚLTIPLES ROBOTS AÉREOS; AVINSPEC – Aerial photoVoltaic Inspection. Investigación en técnicas de localización precisa con múltiples sensores en UAVs sobre plantas fotovoltaicas
INSPECTOR aims at the practical transference to industry of several technologies, tools and research regarding to the automation of inspection processes and industrial maintenance. Particularly, great improvements in efficiency are expected on challenging scenarios (dangerous or difficult to access).
The INSPECTOR consortium is made up two large enterprises (TSK and COMSA), three medium sized enterprises (PREDITEC, TELICE, DIAGNOSTIQA) and three small companies (DRONETOOLS, SYLTEC and TRESCA). Its funded under the Spanish initiative Programa CIEN with a budget of 7,1M € and its duration is 48 months.
The ARM-EXTEND project proposes the development of the first robotic manipulation system with aerial and ground locomotion capabilities in an industrial environment and the first specifically designed for inspection and maintenance purposes in locations with very difficult access. The system will perform works at height that today are carried out manually with important risks of the persons and high operational costs. This system will be able to fly near to the intervention location, land on very constrained surfaces, such as pipes, and roll on the surface performing inspection and maintenance tasks and reaching sites not directly accessible by the flying system. Thus, it will be possible to perform manipulation task with a fixed base overcoming the accuracy limitations of manipulation with a floating base and decreasing the energy consumption allowing to increase the duration of the missions, which is very constrained in aerial manipulation.
The scientific and technological objectives of ARM-EXTEND are the following:
– Development of the first aerial robotic manipulator with both aerial and ground locomotion capabilities increasing accuracy in manipulation (millimiter accuracy) and improving drastically the duration of the missions of the aerial manipulation systems based on multi-rotor which is only few minutes. The rotary wing configuration will have multiple rotors with tilted axis (vectorized thrust) to provide more agility overcoming the limitation of conventional multi-rotor platforms with parallel axis.
– Develop autonomous landing on pipes and other constrained surfaces by using 3D environment perception system with both visual and laser sensors. The landing system will benefit from the agility of the multi-rotor with tilted axis.
– Manipulation by using light robotic arms overcoming the accuracy and dexterity that can be achieved while the robot is flying without any contact point. Thus, the manipulator will be able to perform wall tickness measurements and installation of permanent sensors.
– Collaborate with other aerial robots in inspection and maintenance activities. Thus, a fleet of aerial robotic inspectors will be able to detect and localise leaks and determine the locations to be inspected by the aerial robotic manipulator to perform wall tickness and other measurements requiring contact.
The above objectives are complex but can be achieved by using the very relevant previous results of the research team that has pioneered the aerial robotic manipulation and play a leadership role in this area and its applications to inspection. The ARM-EXTEND system will be able to perform contact and non contact inspection in energy generation plants decreasing dramatically maintenance costs and avoiding contamination due to leakages or even explosions due to gas losses. The project will perform experiments in pipe inspection an maintenance, which is a very relevant activity with a huge economic impact.

AEROMAIN: Sistema de manipulación mediante robots aéreos para el mantenimiento en la generación y distribución de energía. Aplicación a los aerogeneradores.
AEROMAIN proposes the development of the worldwide first aerial robotic system with advanced manipulation capabilities to be applied in inspection and maintenance of energy systems and particularly in the maintenance of wind turbines, including contact inspection (i.e. ultrasonic inspection) and blade repairingof surface damagesor even “materials lost” of impacted areas (leading edge). These operations are today very costly and performed manuallyin risky conditions with experts that have to climb, using for example a rigging system, to inspect specific areas and to perform repairing. The application of crawler robots with magnetic wheels does not solve the problem because the blades of many new wind turbines are made of composites and the crawler should be deployed and maintained.
The proposed aerial robotic manipulation system will avoid the above problems providing the capability of flying and performing not only visual inspection but also contact inspection and repairing. Then, the technical objective of AEROMAIN is design and development of a multi-rotor platform that can fly and manipulate with the coordinated motion of two arms for repairing applications where it is not possible to grab and dock to the structure. The two arms are required for two hand manipulation, to provide a fixed contact point while manipulating with the second hand,and to locate a camera or other sensor in an appropriated visualization position for manipulation with the other arm. This objective includes the development of perception functionalities for mapping, positioning, obstacle detection and active cooperative perception. Also includes motion planning for efficient and safe grabbing and manipulation, torque compensation, as well as reactive behaviours to increase safety.
The above objectives are very challenging but can be achieved using the results obtained in the very successful FP7 ARCAS on aerial robotics cooperative assembly system, coordinated by the AEROMAIN coordinator,that has demonstrated the first manipulation in the world with helicopters and multi-rotors with 6 and 7 Degrees of Freedom (DoF) arms, including industrial arms. In this project the basic control, perception and planning methods for assembly by means of aerial robots have been developed and appliedto bar grasping and structure assembly. These results open a unique opportunity to produce step changes in aerial manipulation required for achieving relevant industrial results in inspection and maintenance of energy systems and particularly in the maintenance of wind turbines in Spain, that has been identified as an extremely promising application with more than 20,000 wind turbinesinstalled and estimated maintenance costs of 400M€per year.

REFLEX: Robot for aircraft flexible riveting
FEDER-INNTERCONECTA programme from Spanish CDTI, funded by INASOR
Riveting involves pre-drilling both parts with adequate accuracy for the later insertion of the rivet. The precision in the positioning hole is critical to the process. At present there are fixed riveting automatic or semiautomatic machines in the aircraft industry, but lack the versatility to accommodate different positions of the airplane surfaces and in real time. Moreover, the economic cost of these machines makes unfeasible the use of different machines for riveting simultaneously in different parts or airplane surfaces.
This project aims to design a robotic machine for flexible riveting which is able to adapt to any surface of the aircraft and can be used efficiently in different programs. It will be a portable robotic machine, capable of drilling, insert rivets with interference and sealant applied independently. This machine will be able to locate the rivet points based on information previously given by an operator and navigate to them and do the whole process.

The system should be able to operate in different weather conditions, day and night and in any location.
The AICIA team develops research and development activities on autonomous landing by using on-board sensors to estimate the relative motion, position and orientation between the UAV and the landing platform. Particularly, computer vision techniques, by means of real-time image processing on-board the helicopter, are applied. First, a reliable interest point detector will be necessary. Those points can be computed based on segmentation together with known patterns to increase the reliability of the system. Once detected such points, relative position and orientation can be estimated based on homography techniques. These estimations should be fused with the ones obtained by means of other on-board sensors, including range measurements and differential GPS, to increase the reliability.
The AICIA team also works on the design of landing control laws taking into account the dynamic model of the helicopter and the model of the platform motion. Then, the team is working on helicopter modeling, and on the analysis of different control methods. A method based on internal model and trajectory planning taking into account the helicopter motion constraints has been proposed. The on-board control system should be able to identify in real-time a suitable model of the platform motion to be synchronized with the helicopter motion.

HADA is a vertical takeoff and landing (VTOL) aircraft convertible in flight, capable of taking off, landing and hovering as a conventional helicopter, and flying on cruise regime in fixed-wing aircraft configuration with high efficiency. The configuration change from helicopter mode to airplane mode is achieved through mechanisms that make the deployment of the wings and the folding of the main rotor blades. At the same time, there is a transfer of power from the main rotor to the tail propeller.
The initial prototype will be a UAV for surveillance and security missions. The next development will be a passenger jet for regional transport. The HADA project is led by INTA, and involves several companies and research centers in Spain. The GRVC participation focuses primarily on the area of navigation, guidance and control, and modeling and simulation of the transition phase.
PROMA – Fire fighting vehicle chassis control system
Funded by Technological Corporation of Andalusia and PROTEC FIRE, from ITURRI Corporation.
The overall objective of the PROMA project is the design, development and testing of the control system of a special purpose vehicle dedicated to fire fighting.

JACUMAR: SEATAP-JM (System for the Automatic Estimation of the Sizes of Fish in Sea Cages)
The SEATAP-JM system estimates the distribution of sizes of fish wallowing in sea cages in such an automatic way that makes unnecessary the manipulation of the fish or the alteration of the conditions of the cage, making easier the tasks of sampling, and avoiding simultaneously the stress that the above mentioned tasks suppose for the fish. As a consequence the tasks of sampling cages might be done with greater frequency and the results obtained have a better reliability.
This is achieved using computer vision and image processing techniques. In particular we have developed a stereo vision system, composed by two cameras in a submersible housing that is dived in the cages, acquiring images that are processed in a computer system, where they go through a series of algorithms that obtain in an automatic way, without needing the intervention of an operator, measurements of the average weight of the fish in the sampled cage.
