A device forming a robotic hand, including a base forming the palm of a hand, at least two articulated structures each forming a robotic finger, each articulated structure being connected to the base by at least one articulation, at least one drive mechanism for each articulation, at least one actuator designed to actuate the at least one drive mechanism at least by a flexible drive connection connecting and driving the at least one drive mechanism, at least one intermediate driveshaft for relaying the movement of the at least one actuator such that the at least one intermediate drive shaft is actuated by an actuator, and the at least one intermediate shaft is connected to at least two distinct drive mechanisms by the at least one flexible drive connection.

Robotic hand

The invention concerns a device forming a robotic finger comprising a base () forming a palm, at least one knuckle () articulated on the base () about two separate joints () non-parallel to each other, at least two actuators () and cable-linking means () respectively linking the two actuators () to drive elements of said two joints (), characterized in that the device comprises guide means () designed to guide the cables involved in the control of each joint () located after the first joint () on the base (), in a common plane passing through the axis () of said first joint ().
