A waterproof mechanism, for a robot hand, includes a cover covering at least a part of a main body portion of the robot hand, covering a driving portion, and including an opening; and an extension member protruding from the opening, wherein the driving portion is held so as to be driven with respect to the main body portion, a proximal end portion of the extension member is fixed to the driving portion, a distal end portion of the extension member is fixed to a claw member of the robot hand, a first fixing member that fixes the extension member and the driving portion to each other is covered by the cover, and a second fixing member that fixes the extension member and the claw member to each other is detachably exposed from the cover.

A cooling structure and a method of cooling a surgical robot arm. The surgical robot arm extends from a proximal end attached to a base to a distal end attachable to a surgical instrument via a series of links interspersed by articulations. The cooling structure comprises a loop for circumscribing the surgical robot arm. The loop comprises a hollow interior for feeding cooling fluid through the loop, and a series of orifices directed towards the surgical robot arm for feeding cooling fluid from the loop towards the surgical robot arm. The cooling structure further comprises a feeder conduit attached to the loop for feeding cooling fluid from a cooling fluid source to the loop.

A single-axis robot in which a ball screw or a linear guide can be easily replaced is provided. A single axis robot, includes: a housing including, on a first side, a base plate having a first saddle hole; a support plate arranged in a second side of the housing; a linear guide arranged inside the housing along the base plate, the linear guide extending along the first saddle hole; a slider arranged inside the housing on the linear guide, the slider configured to slide along the linear guide; a saddle arranged on the first side of the slider to protrude to an outside of the housing through the first saddle hole; a driving device arranged on the second side of the slider to drive the slider; and a telescopic cover arranged outside the housing between the base plate and the saddle.

The operating safety of a robot is provided. The robot includes two elements that can move relative to one another, a joint with at least one degree of freedom, connecting the two elements; and a flexible elastic film surrounding the joint and attached to each of the two elements, the film being stretched between its attachments in at least one configuration of the two elements.

A boot seal is detachably attached to a joint including: a drive link and link members; and a ball joint for linking them to be relatively rotatable or swivelable. The ball joint includes a ball shank having a shaft section fixed to the drive link and a ball section provided on one end of the shaft section and a holder that is fixed to an end section of each of the link members and that has a ball-receiving section for supporting the ball section in a state where the ball section is surrounded. A cover main body that covers the gap between the ball shank and the holder and that is formed of a flexible material includes through-holes through which the shaft section is made to pass, a slit that continuously extends between the through-holes, and a fastener opening and hermetically closing the slit along the entire length thereof.

The disclosure relates to a robot protecting jacket for a coating robot, in particular for a painting robot, comprising a connecting element for form-fittingly fastening the robot protecting jacket, especially for fastening the robot protecting jacket to the coating robot or connecting two adjacent portions of the robot protecting jacket to each other. The disclosure provides for the connecting element to be part of a beaded connection.

Embodiments provide functionality to prevent collisions between robots and objects. An example embodiment detects a type and a location of an object based on a camera image of the object, where the image has a reference frame. Motion of the object is then predicted based on at least one of: the detected type of the object, the detected location of the object, and a model of object motion. To continue, a motion plan for the robot is generated that avoids having the robot collide with the object based on the predicted motion of the object and a transformation between the reference frame of the image and a reference frame of the robot. The robot can be controlled to move in accordance with the motion plan or a signal can be generated that controls the robot to operate in accordance with the motion plan.

Current technologies allow a robot to acquire a tool only if the tool is in a set known location, such as in a rack. In an embodiment, a method and corresponding system, can determine the previously unknow pose of a tool freely placed in an environment. The method can then calculate a trajectory that allows for a robot to move from its current position to the tool and attach with the tool. In such a way, tools can be located and used by a robot when placed at any location in an environment.

In an embodiment, a method includes identifying a force and torque for a robot to accomplish a task and identifying context of a portion of a movement plan indicating motion of the robot to perform the task. Based on the identified force, torque, and context, a context specific torque is determined for at least one aspect of the robot while the robot executes the portion of the movement plan. In turn, a control signal is generated for the at least one aspect of the robot to operate in accordance with the determined context specific torque.

In an embodiment, a method and system use various sensors to determine a shape of a collection of materials (e.g., foodstuffs). A controller can determine a trajectory which achieves the desired end-state, possibly chosen from a set of feasible, collision-free trajectories to execute, and a robot executes that trajectory. The robot, executing that trajectory, scoops, grabs, or otherwise acquires the desired amount of material from the collection of materials at a desired location. The robot then deposits the collected material in the desired receptacle at a specific location and orientation.
