| Abstract | ||
| Human-computer interface device of haptic kinesthetic type, capable of engaging directly with a human that manoeuvres it exchanging forces generically oriented in space in at least two points of contact with the user. An exemplary embodiment comprises a couple of kinematical open chains (1 and 2), symmetrically connected to a support (10) that can be fixed to a forearm (4) of an operator. The two kinematical chains (1 and 2) are articulated respectively in the axes (5, 6, 7 and 5', 6', 7') and end with a respective interaction element (3 and 3'). The kinematical chain (1) has three links (20, 30 and 40), and is characterized by three actuated degrees of freedom, distributed onto the three links, and three passive degrees of freedom concentrated in the interaction element (3) with one of the distal phalanxes of the hand of the user arranged at the free end of the kinematical chain. The first link (20) is pivotally connected to a base (21) integral to the support (10) and can rotate about an axis (5) perpendicular to the plane of the support (10). The second link (30), is obtained from a tubular stem having a first end pivotally connected to the first link (20) by a rotational joint about an axis (6) and a second end pivotally connected to the third link (40) by a rotational joint about another axis (7) perpendicular to that of the first end. Each of the two kinematical chains (1 and 2) of the haptic interface comprises an unit of three rotational motors (130, 131, 132) arranged at each of the two ends of the support (10). The forces generated by said rotational motors are, moreover, transmitted to the joints of the kinematical chain by a system of: tendons, "capstan" with circular sectors and idle pulleys. | ||
