Traditionally, the design of robotic systems has focused on achieving robust and efficient models, optimized for a specific task. However, at the end of the last century, a novel idea started to grow up which consisted in designing machines and mechanisms capable of carrying out several tasks, thus offering higher flexibility and versatility. To sum up, the target is to get multioperational systems in such a way that the robots can change their configuration to execute multiple tasks. Nowadays, the technical chance exists to design and install them in several fields such as mounting small series of large components in the aeronautical and eolic field, flexible tasks in packing and folding, deployable antennas and trusses, biomedical and rehabilitation applications […] Read more >>

CompMech has a lengthy trajectory in the design of parallel kinematic machines, has developed tasks on stiffness analysis, vibrations and mechatronics in the scope of the National Research Program. Lately, the group has been researching into the field of large deformations applying to closed loop flexible mechanisms. Parallel kinematic machines, comprising articulated rigid links, have reached maturity and a predominant position in the field of industrial manipulators and high precision micro positioning systems. Small deformations and vibrations in such systems are compensated as in serial machines. On the other hand, in ultra flexible machines, kinematic pairs are removed to generate the motion with the large deformations of their elements. […] Read more >>

Design of Multiaxial Parallel Kinematic Machines with High Dynamic Capabilities (DYNAMECH). Multi-axis machines are linkage-based systems able to generate in their end-effector a coupled motion combining translations and rotations. The main applications are the multi-axis testing tables, flight simulators, vehicle simulators, etc. Nowadays, the configuration of the multi-axis testing tables (MAST) is based on a moving platform coupled to at least three actuators. In the case of the simulation systems, the traditional structure used is the hexapod. This limited scope of design alternatives is mainly due to the lack of theoretical bases in this field, which still needs a further scientific development. In this sense, the platform motion is particularly complex  […] Read more >>

The Research and Training Unit is comprised of five research groups belonging to the Department of Mechanical Engineering at the Faculty of Engineering in Bilbao, University of The Basque Country (UPV/EHU). Its main objectives cover three important fields: sustainability engineering and structural and mechanic design, high performance eco-manufacture and sustainability construction.

The activities of the Compmech Research group are focused on sustainability engineering and structural and mechanical design. Inside this area works enclose basic and applied research regarding eco-design, calculus and mechanical analysis of structural components, mechanisms and machines. […] Read more >>

The project entitled Mechatronic analysis of multi-axis agile machines and funded by the University of the Basque Country has several objectives. The first one is the development of a procedure for the mechatronic modelling of a parallel kinematic mechanism. This procedure has to include the control algorithm, the location of the sensors, the kinematics and dynamics of the mechanism and the dynamic of the actuators. Apart from that, we should be able to select the best control option for a parallel kinematic machine, taking its dynamic, the position of the sensors and its actuators into account […] Read more >>

This project deals with the mechatronic design of machines with parallel kinematics. It focuses not only on the methodology, but also on the use of analytical mechanics in order to simplify the study of the dynamics of the manipulator, on the integral modelling of the mechanical-mechatronic system and on the experimental identification of parameters of the actuators – such as friction. The methodology has been applied and satisfactorily validated by the redesign and experimental analysis of the prototype of a parallel manipulator. […] Read more >>
