Mechatronics and Industrial Robotics Lab

Description

The Mechatronics and Industrial Robotics Lab is mainly dedicated to the design and testing of automatic machines and robots; the concepts of new machines are developed and often brought up to the level of laboratory prototypes; in other cases the same prototypes or industrial mechanical systems are used for the development of advanced or unconventional automated applications. Biomechanics projects have been recently addressed too.

Research activities

The research activity carried out in the Mechatronics and Industrial Robotics Lab has led over the years to the design and construction of several prototype robots for research purposes or for industrial applications. These include I.Ca.Ro., a 3-axis robot with a parallel kinematics characterized by pure translational motions, and Sphe.I.Ro., a 3-axis robot with a parallel kinematics characterized by pure rotation motions. Various 3-axis modular and reconfigurable machines have been designed in such a way as to generate, alternatively, translation or rotation motions. In addition, a mini-platform of orientation has been designed, characterized by two degrees of freedom of rotation and used for the assembly of miniaturized components. In the field of advanced robotics, prototypes of biomorphic submarine robots were developed in cooperation with DII researchers.
Among the applications to industrial processes, it is worth quoting the researches on the use of parallel robots for incremental forming or for friction stir welding. Furthermore, a vision system servoed to a 3-axis robot was developed, aimed at creating a visual control in the operative space, as well as research on impedance controllers and based on neural networks or fractional derivatives.
