Dear Friends and Colleagues,
it is a pleasure to announce that SynGrasp, a new Matlab Toolbox on ``Uderactuated Robotic
Grasping'' that we developed at the University of Siena is now available at
The main features of the SynGrasp toolbox are:
- hand modeling: robotic hand models can be easily defined. Four hand models are already available:
an anthropomorphic hand, a 3-fingered hand, a modular hand and the DLR/HIT II Hand.
- grasping modeling: the grasping hand configuration, contact points, Grasp and Jacobian matrices
can be computed. Controllable internal force subspace, rigid-body motion, manipulability
ellipsoids can be evaluated.
- grasp analysis: different grasp quality measures are available in the toolbox. Tools for the
evaluation of the optimal force distribution are provided. Furthermore, the toolbox allows to
perform kinematic and force manipulability analysis, taking into account the joint coupling
induced by the underactuation and hand compliance.
- graphics: a set of functions have been designed to simplify the graphical representation of the
manipulator. These functions can be used together with built-in Matlab functions to render the
hands in contact with objects of arbitrary shapes. Moreover motions due to synergy activation can
- development: the toolbox is intended to be a continuously growing toolbox. This can be possible
also thanks to your help. Send us comments, suggest new functions to be included or report to us
problems or code bugs and, even more importan, let us know if you are interested in developing
modules or integrating your own modules in SynGrasp! The help syntax will be used to recognize the
work of developers.
The toolbox is freely available and we plan to include more functions that you might suggest or
