Force/torque sensor, apparatus and method for robot teaching and operation
This invention relates to force/torque sensor and more particularly to multi-axis force/torque sensor and the methods of use for directly teaching a task to a mechatronic manipulator. The force/torque sensor has a casing, an outer frame forming part of or connected to the casing, an inner frame forming part of or connected to the casing, a compliant member connecting the outer frame to the inner frame, and one or more measurement elements mounted in the casing for measuring compliance of the compliant member when a force or torque is applied between the outer frame and the inner frame.

Virtual tools for programming a robot arm
A robotic device may: receive movement information associated with a plurality of subtasks performed by a manipulator of a robotic device, where the movement information indicates respective paths followed by the manipulator while performing the respective subtasks and respective forces experienced by the manipulator along the respective paths; determine task information for a task to be performed by the robotic device, where the task comprises a combination of subtasks of the plurality of subtasks, where the task information includes a trajectory to be followed by the manipulator, and forces to be exerted by the manipulator at points along the trajectory; and determine, based on the task information, torques to be applied over time to the manipulator via a joint coupled to the robotic device to perform the task.
MEDICAL OBSERVATION DEVICE
A medical observation device includes an imaging unit configured to photograph an image of an operation site, and a holding unit configured to be connected with the imaging unit and have rotary shafts which are operable with at least six degrees of freedom. Among the rotary shafts, at least two shafts are active shafts whose driving is controlled based on states of the rotary shafts, and at least one shaft is a passive shaft which is rotated according to direct external manipulation accompanying contact.
COOPERATION ROBOT FOR VEHICLE PRODUCTION SYSTEM AND METHOD FOR CONTROLLING THE SAME
A cooperation robot for moving a bumper to a predetermined position of a vehicle in a vehicle production system includes: a multi-axis arm, a front end portion of which is connected to and a rear end portion of which is connected to a robot body so that the multi-axis arm is movably disposed to upper, lower, left and right sides on the basis of the robot body. The multi-axis arm is disposed to rotate the gripper. A force torque (FT) sensor is disposed between the multi-axis arm and the gripper and detects a direction of external force which is applied to the gripper and the bumper gripped by the gripper. An operator controls the multi-axis arm so that positions of the gripper and the bumper vary. A controller controls the operator according to the direction of the external force detected by the FT sensor when the multi-axis arm is in a stand-by condition to move the gripper in the direction the external force.
Vision-guided robots and methods of training them
Via intuitive interactions with a user, robots may be trained to perform tasks such as visually detecting and identifying physical objects and/or manipulating objects. In some embodiments, training is facilitated by the robot's simulation of task-execution using augmented-reality techniques.
Micro-force guided cooperative control for surgical manipulation of delicate tissue
A method and system for micro-force guided cooperative control that assists the operator in manipulating tissue in the direction of least resistance. A tool holder receives a surgical tool adapted to be held by a robot and a surgeon. A first sensor measures interaction forces between a tip of the surgical tool and tissue of a region of interest. A second sensor measures interaction forces between the surgeon and a handle to the surgical tool. A data processor is configured to perform an algorithm to actively guide the surgical tool by creating a bias towards a path of least resistance and limit directional tool forces of the surgical tool as a function of handle input forces and tip forces. This function offers assistance to challenging retinal membrane peeling procedures that require a surgeon to delicately delaminate fragile tissue that is susceptible to hemorrhage and tearing due to undesirable forces.

METHOD AND MEANS FOR HANDLING AN OBJECT
A method for handling an object comprises the steps: a) connecting the object (1) with a manipulator (5) and with an input tool (7) by means of which a direction ({right arrow over (d)}) within an internal coordinate system (K) relating to the input tool (7) can be entered, d) initiating a test movement of the manipulator (5) on the basis of a direction ({right arrow over (r)}) known in the external coordinate system (K); e) determining the direction ({right arrow over (r)}) of a movement of the input tool (7) in the internal coordinate system (K) resulting from the test movement of the manipulator (5); f) determining a coordinate transformation (T) which transforms the direction of the resulting movement ({right arrow over (r)}) in the internal coordinate system into the known direction ({right arrow over (r)}) in the external coordinate system; g) detecting an internal direction ({right arrow over (d)}) within the internal coordinate system (K) entered by a user using the input tool (7); h) applying the coordinate transformation (T) to the detected internal direction ({right arrow over (d)}) in order to obtain an external direction ({right arrow over (d)}); and i) controlling a movement of the manipulator (5) on the basis of the external direction ({right arrow over (d)}).
