Various embodiments of the present invention generally relate to prosthetic partial finger designs that can mimic the last two joints of the finger. Some embodiments include a proximal phalange, a distal phalange coupled to the proximal phalange, and a knuckle track (e.g., formed in an arc). The knuckle track can be moveably coupled to the proximal phalange an may include multiple teeth formed on which the proximal phalange slides along. A ratcheting mechanism can contact the multiple teeth to allow sliding in only a first direction while the ratcheting mechanism is engaged. Some embodiments include a release mechanism (e.g., a button) configured to disengage the ratcheting mechanism from the multiple teeth to allow the distal phalange to slide in a second direction. In some embodiments, the device may include a spring-back capability that automatically extends the finger after reaching full finger flexion, enabling one-handed use.

Low-cost prosthetic apparatus, methods, kits, and systems with improved force transfer elements are disclosed. For example, the prosthetic apparatus may comprise: a plurality of first components manufactured from a first material to define 3D shapes with exterior surfaces resembling digits of a human hand; and a plurality of second components manufactured from a second material to define 2D shapes that are rotatably engageable with the 3D shapes to define force transfer elements operable to close the digits around an object responsive to a pull force applied to the force transfer elements, wherein the first material is different from the second material. Methods for manufacturing and assembling prosthetic apparatus also are disclosed along with related kits and systems.

A robotic assembly control system is disclosed. The robotic assembly control system includes an exoskeleton apparatus adapted to be worn by a user, at least one robotic assembly, the at least one robotic assembly controlled by the user by way of the exoskeleton, and at least one mobile platform, the at least one mobile platform controlled by the user and wherein the at least one robotic assembly is attached to the at least one mobile platform.

A below-elbow prosthetic arm assembly includes a hand; an arm connected to the hand; a cylinder connected to the arm; and a string connected to the rear end of the cylinder. To start using the prosthetic arm, the user's amputated upper limb is enclosed by the cylinder and tied thereto with a string. The below-elbow prosthetic arm assembly further includes an expansion kit adapted to meet the user's needs in daily lives, learning and sports. The expansion kit is directly fitted to the hand. Function expansion is achieved without removing the hand. Therefore, the below-elbow prosthetic arm exhibits enhanced ease of use and minimizes the user's financial burdens which might otherwise arise from ordering customized prosthetic arms for use in different activities.

An artificial wrist comprising including a static body adapted to be bound to a support; a movable body adapted to be bound to an end effector; and a junction block defining an axis of rotation between the static body and the movable body and comprising including a cable suitable to be moved by mutual rotation of the bodies and around the axis of rotation, and elastic member placing the cable under tensile stress and working in opposition to the movement of the cable so as to define a rest position in which the cable and the elastic member exerts a zero resulting torque on the bodies and, and an activation position in which they exert a non-zero resulting torque on the bodies and, bringing the bodies and back to the rest position.

A prosthetic arm apparatus comprising a plurality of segments that provide a user of the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connectable to one another and connectable to a harness mount that may be adorned by the user. Each segment of the plurality of segments provides a portion of the movement capability, enabling the plurality of connected segments connected to the harness mount to provide substantially the same movement capability as that lacking in the user.

A universal digit is formed to be attachable to the residual digit of a patient, and to have a lockable joint, so as to provide considerable utility and flexibility. The structure of the joint member allows the universal digit to be easily adjusted and manipulated so that the extension portion can be locked into multiple positions by easily manipulating adjustment buttons. The extension is rotatable about a first longitudinal axis, and is further rotatable about a transverse axis which is perpendicular to the longitudinal axis. The joint structure thus has three dimensions of movement and provides a significant number of diverse options for positioning of the extension. Unique locking mechanisms within the various structures allow the universal digit to be rigidly held in the desired position, thereby increasing the utility for a patient/user.

A prosthetic device control apparatus includes at least one sensor worn by a user. The sensor(s) determines a user's movement. A control module is in communication with the sensor(s). The control module communicates movement information to a prosthetic. A method for controlling a prosthetic device includes sensing a user's movement, communicating the movement through a control module to a prosthetic device; and controlling the movement of a prosthetic device.
