The invention relates to a gripping device, such as an automated hand, comprising a plurality of metacarpal members, each metacarpal member having a first end attached to a support frame via a universal joint and having a second end attached to a gripping member, wherein the metacarpal members are able to pivot upwardly, downwardly and laterally. Where adjacent metacarpal members together form a palm of the hand, the ability of the metacarpal members to move up, down and laterally helps the palm to grip an object and also helps the palm to withstand at least some forces from above, below and from the side.

The invention refers to the area of control of a limb device in the form of an artificial limb for a human or a robot limb. In particular, the invention is related to a control unit for electrically controlling an electrically controllable limb device, the limb device comprising a plurality of actuators, the control unit comprising a first interface for connecting the control unit to the limb device, the control unit comprising a second interface for connecting the control unit to a data gathering device comprising one or more sensing devices, the control unit comprising a processing unit which is arranged for controlling the limb device at least based on data gathered by the data gathering device, wherein the control unit is arranged for outputting one single control action step to the actuators of the limb device calculated by the processing unit based on a first data or data combination received from the data gathering device, and the control unit is arranged for outputting a plurality of control action steps to the actuators of the limb device calculated by the processing unit based on a second data or data combination received from the data gathering device, the second data or data combination being different from the first data or data combination, the plurality of control action steps inducing a more complex automatic movement of the limb device that the one single control action step. The invention further refers to a system comprising such a control unit, a method for controlling an electrically controllable limb device and a computer program.

A body-powered articulated prosthetic hand where each of the segments of the digits, the palmer plate, the thumb pivot plate and the wrist are individually sizeable. This allows for both a proportionately scalable hand as well as individual customization of geometric configurations tailored to specific use patterns. The hand is crushable since it has flexible and pivotable connections between digits along the length and width of the hand. It has a hollow member construction that imparts a strong lightweight design. It is modular so individual parts can be replaced for quick repair. From an aesthetics point, it is visually pleasing and can be offered in different colors, and with custom digit sleeves for specific applications. Fingers can be operated individually or in groups via pairs of cables which allow operation in either voluntary open or voluntary closed modes of control. The flexible construction allows gripping of irregularly shaped objects and deforms before failing giving indication of overload prior to failure.

The present invention provides a prosthetic socket (10) having a longitudinal axis X for attachment to a limb of a patient having first and second sides (A, B) which comprises a first portion (20) having a first edge (22), a second edge (24) a first end (26) and a second end (28) and second portion (30) having a first edge (32) a second edge (34) a first end (36) and a second edge (38). A hinge (40) is connecting the first edge (22) of the first portion (20) to the first edge (32) of the second portion (30) and a clasp (50) is provided between the second edge (24) of the first portion (20) and the second edge (34) of the second portion (30). Such an arrangement allows for a prosthetic socket (10) to be more easily attached and removed to a patients limb.

An artificial epidermis structure capable of using a gel substance to adjust a frictional property with high precision is provided. When a front surface of a lid member comes into contact with a target object and pressure acts on the lid member, a part of the gel substance can escape into a space that is formed by concave portions on a front surface of a gel substance. Therefore, reduction in a repulsion force of the gel substance is achieved. Accordingly, the pressure can be appropriately transmitted to the gel substance via the lid member, and convex portions of the gel substance can be caused to easily bulge out over the front surface of the lid member via holes of the lid member.

An artificial arm in which a finger is bent is proposed. The artificial arm includes an insertion portion inserted into a tip of the finger, a tendon wire which is connected to a lower portion of the insertion portion and allows the insertion portion to perform a joint movement, an adjustment unit which is located on a back of a hand and adjusts tension of the tendon wire, and a connection unit which is made of an elastic material and having one end which is connected to the tendon wire so that an end of the tendon wire faces the adjustment unit and having the other end which is connected to the adjustment unit.

An upper limb prosthetic device may comprise a hybrid-drive prosthetic device that includes one or more actuators fixed to a first arm portion and one or more cables extending from the one or more actuators along one or more cable paths defined through the first arm portion and a second arm portion to a terminal device/device assembly, where the one or more cables are configured to be actuated by the one or more actuators and are further configured to be actuated by pivoting the second arm portion toward the first arm portion, Alternatively, or additionally, the upper limb prosthetic device may comprise a modular prosthetic device that includes a modular terminal device assembly with removably coupled first, second, and third modular links configured to control the respective yaw, pitch, and roll of an end effector (e.g a prosthetic hand, a tool, an instrument or any other attachment).

The artificial body part control system using ultrasonic imaging includes of an ultrasonic transducer coupled with an ultrasonic image analyzer which may be adapted to transmit a control signal to an artificial body part.

A mobility augmentation system monitors data representative of a user's motor intent and augments the user's mobility based on the monitored motor intent data. A machine-learned model is trained to identify an intended movement based on the monitored motor intent data. The machine-learned model may be trained based on generalized or specific motor intent data (e.g., user-specific motor intent data). A machine-learned model initially trained on generalized motor intent data may be re-trained on user-specific motor intent data such that the machine-learned model is optimized to the movements of the user. The system uses the machine-learned model to identify a difference between the user's monitored movement and target movement signals. Based on the identified difference, the system determines actuation signals to augment the user's movement. The actuation signals determined can be an adjustment to a currently applied actuation such that the system optimizes the actuation strategy during application.

The invention relates to an automated hand, such as a prosthetic hand. In one form, the automated hand may be fluid compatible. In one form, the automated hand may comprise features to reduce the risk of harm to motors and/or other sensitive components of the hand when subject to an impact. In one form, the hand may comprise a wrist joint configured to allow the hand to curl and flex and/or to rotate. In one form, one or more digits of the hand may be individually controlled. In one form the hand may include a thumb rotation locking mechanism. In one form the hand may be provided with removable grip plates. In one form, the hand may be configured for use as a training hand.
