From September 10th to 12th 2014 I will be attending the 10th IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications (in Senigallia - Ancona - Italy).

There I will present the OSHap project, whose aim is to develop an open-source haptic device. During the conference it will be presented the process of designing of the systems. Everything has been carried out by means of several Virtual Prototyping techniques applied to the development of novel haptic devices.

Together with Francesco Ferrise and Monica Bordegoni from the KAEMaRT group - POLIMI, we submitted the paper "Design of an Open‐Source Low Cost 2DOF Haptic Device". Here you can find the abstract of our paper


 
Title Design of an Open‐Source Low Cost 2DOF Haptic Device
Authors  A.Lavatelli, F.Ferrise, M.Bordegoni
Abstract The paper describes the design and preliminary virtual testing of OSHap, an open-source low cost 2DOF haptic interface. The aim of the research is to create a mechatronic platform for haptic interaction based mainly on cheap and open source components. The results will be distributed freely in order to provide guidelines for expert users to develop their own haptic interface. Both the mechanical design philosophy and the control electronics are hereby discussed together with a preliminary testing made by using virtual prototyping tools. The kinematic layout is based on a serial double joint scheme. This choice is claimed to be the less expensive one, inasmuch as tolerances do not have to be narrow as for the parallel systems. The system also allows future users to tune dimensions (and relative workspace) easily. The interface is admittance controlled for maximizing the transparency with low cost drives. The device is based on the Intel Galileo open-source development board: this board embeds a powerful chip-sets that enables us to perform real-time 2DOF control tasks that are hardly reachable with the most common open source electronic platforms. All the choices listed above are discussed and evaluated, with focus on performance-to-cost ratio.
