Abstract: A guiding and support device, particularly for a robot for minimally-invasive surgery through a single parietal incision and/or natural orifice, includes mutually associated rigid bodies, and stiffening elements associated with the guiding and support device and adapted for the transition of the device from an inactive configuration, the rigid bodies can move with respect to each other, to an active configuration, in which the rigid bodies are mutually aligned so as to define a rigid guide, and vice versa. The device further includes elements for combined rotary and translational motion which are adapted, in the active configuration of the guiding and support device, to translate and/or to rotate a robot.

Abstract: An articulated device for robotic systems includes three rigid bodies. The first rigid body is configured to rotate about a first rotation axis with respect to a rigid base body. The second rigid body is configured to rotate about a second rotation axis with respect to the first rigid body. The third rigid body is configured to rotate about a third rotation axis with respect to the second rigid body. The first, second, and third rotation axes coincide in at least one point which defines the center of rotation of the articulated device.
