A robotic system includes a base, a grounding arm, a working arm, and one or more sensors. The grounding arm extends from the base and is configured to be coupled to a fixed structure within the mouth of the patient for establishing an origin for the robotic system. The working arm extends from the base and is configured to be coupled with one or more tools for use during an installation of a dental implant in the mouth. The one or more sensors are for monitoring positions of the grounding arm and/or the working arm and to generate positional data that is used to create a post-operative virtual three-dimensional model of at least a portion of the mouth of the patient.
摘要:
A pneumatically powered, fully untethered mobile soft robot is described. Composites consisting of silicone elastomer, polyaramid fabric, and hollow glass microspheres were used to fabricate a sufficiently large soft robot to carry the miniature air compressors, battery, valves, and controller needed for autonomous operation. Fabrication techniques were developed to mold a 0.65 meter long soft body with modified Pneumatic network actuators capable of operating at the elevated pressures (up to 138 kPa) required to actuate the legs of the robot and hold payloads of up to 8 kg. The soft robot is safe to handle, and its silicone body is innately resilient to a variety of adverse environmental conditions including snow, puddles of water, direct (albeit limited) exposure to flames, and the crushing force of being run over by an automobile.

摘要:
A robotic actuator includes an internal anchor and an instrument. The internal anchor is adapted to be inserted into a body via an entrance port, positioned inside the body, and magnetically coupled with an external anchor positioned outside the body. The instrument is adapted to be inserted into the body via the entrance port and secured to the internal anchor. The instrument includes an end-effector having multiple degrees of movement via multiple axes, and a plurality of actuators that provide the multiple degrees of movement. A surgical system includes a manipulator, an implantable actuator and a controller. The manipulator includes a plurality of integrated sensor/actuators. The sensors of the sensor/actuators are adapted to detect movement about a plurality of axes of movement. The implantable actuator includes a plurality ofjoints providing a plurality of axes of movement. The controller is configured to receive information from the plurality of sensor/actuators that indicates movement of the manipulator about the plurality of axes and to cause the joints of the actuator to move along corresponding axes of movement. Each sensor/actuator of the manipulator detects movement about an axis of movement corresponding to a similar one of the joints of the actuator.
