Provided is a rehabilitation and training gaming system that can comprise a mechanism of detecting user inputs, such as a camera, joystick, force sensor, position sensor, inertial sensor, robotic interface, bioelectrical signal sensor, etc., computing unit(s) for processing inputs and generating outputs, and a computer-rendered object that is at least partially controlled by the user's inputs in a physics-driven manner. The physics-driven manner involves the computer-rendered object responding to user inputs in a manner which is both continuous and time-dependent, including but not limited to: a viscosity relationship, where the velocity, or rate of change, of a property of the computer-rendered object is proportional to the user's input, or an inertial relationship, where the acceleration, or second time derivative, of a property of the computer-rendered object is proportional to the user's input.

Rehabilitation and training gaming system to promote cognitive-motor engagement

A mechanical translation apparatus includes a translation stage and a translation assembly operatively connected to the translation stage so as to impart linear motions to the translation stage substantially free of rotational motions. The translation assembly includes a plurality of at least three arms pivotably connected to the translation stage at a first end of each arm of the plurality of at least three arms. The mechanical translation apparatus also includes a base assembly in which each arm of the plurality of at least three arms is also rotationally connected to the base assembly at a second end of each arm. Each arm of the plurality of at least three arms includes three rigid elongate structures arranged substantially parallel and non-coplanar with respect to each other so as to act in cooperation to cancel torques so that substantially purely linear motion is imparted to the translation stage by the plurality of at least three arms, and the translation assembly constrains motion of the translation stage to be substantially purely translational motion free of rotational motion. A robot includes the mechanical translation apparatus.

Delta mechanism with enhanced torsional stiffness

A system for stereo reconstruction from a monoscopic endoscope includes an image pick-up element at a distal end thereof and a working channel defined by a body of the monoscopic endoscope. The system comprises a light patterning component configured to be disposed within the working channel such that a light emitting end of the light patterning component will be fixed with a defined relative distance from the distal end of the image pick-up element. The system also includes a data processor adapted to be in communication with the image pick-up element. The light patterning component forms a pattern of light that is projected onto a region of interest. The data processor receives an image signal of the region of interest that includes the pattern, and determines a distance from the endoscope to the region of interest based on the image signal and based on the defined relative distance.

A cooperatively controlled robotic system includes a main robot assembly, and an arm assembly comprising a proximal end and a distal end. The arm assembly is connected to the main robot assembly at the proximal end. The system also includes a tool assembly connected to the arm assembly at the distal end, a first force sensor between the distal end of the arm assembly and the tool assembly, and a second force sensor between the proximal end of the arm assembly and the main robot assembly. The system includes a control system that is configured to determine a force applied at the first force sensor based on a force detected by the second force sensor, and to compare the determined force to a force detected by the first force sensor to detect a failure of at least one of the first and second force sensors.

Cooperatively-controlled surgical robotic system with redundant force sensing

According to some embodiments of the present invention, a cooperatively-controlled robot includes a robotic actuator assembly comprising a tool holder and a force sensor. The cooperatively-controlled robot further includes a control system adapted to communicate with the robotic actuator assembly and the force sensor, and an actuator in communication with the control system and mechanically coupled to a tool. The force sensor is configured to detect a vibrational force applied on the tool and send a signal to the control system based on the vibrational force. The control system is configured to receive the signal and determine a force to apply to the tool to damp the vibrational force. The control system then signals to the actuator to apply the determined force, and the actuator applies the determined force to actively damp a vibration of the tool.

A cooperative-control robot includes a base component, a mobile platform arranged proximate the base component, a translation assembly operatively connected to the base component and the mobile platform and configured to move the mobile platform with translational degrees of freedom substantially without rotation with respect to said the component, a tool assembly connected to the mobile platform, and a control system configured to communicate with the translation assembly to control motion of the mobile platform in response to forces by a user applied to at least a portion of the cooperative-control robot. The translation assembly includes at least three independently operable actuator arms, each connected to a separate position of the mobile platform. A robotic system includes two or more the cooperative-control robots.
