This quantity comprises the court cases of the 1st overseas convention of IFToMM Italy (IFIT2016), held on the collage of Padova, Vicenza, Italy, on December 1-2, 2016. The ebook comprises contributions at the most recent advances on Mechanism and computing device technological know-how. The fifty-nine papers take care of such themes as biomechanical engineering, heritage of mechanism and computer technological know-how, linkages and mechanical controls, multi-body dynamics, reliability, robotics and mechatronics, transportation equipment, tribology, and vibrations.

The controller for the needle, a MPC-based approach [5], was implemented in C++ using Quadprog++ as the quadratic programming solver. 7) and the CVXOPT optimization library. 7 mm, was attached to the sensor groove of one of the segments to measure the position of the needle tip. 5 wt%, was used as the tissue phantom in the experiments, with a Young’s modulus, E = 7 kPa. The parameters used for the control system are shown in Table 1. 2 Segment Offset Versus Curvature Calibration Before determining the performance of the system, the needle prototype’s steering performance was evaluated.

For example, concentric tube based needle systems operate well inside a cavity but suffer from important kinematic constraints when used percutaneously [4, 12]. Bevel and kinked tip needle steering systems are accurate and have a good range of possible curvatures, but the needle must be rotated as it is inserted, causing additional trauma to the surrounding tissue [11] although in some tissues and scenarios this effect may be negligible [9]. In light of these weaknesses, our group has developed a flexible needle controlled using a biologically inspired multi-segment design [6].
