Disclosed herein are systems, devices, and methods for real-time determinations of likelihoods for possible trajectories of a collaborator in a workspace with a robot. The system determines a current kinematic state of the collaborator and determines a goal of the collaborator based on occupancy information about objects in the workspace. The system also determines a possible trajectory for the collaborator based on the goal and the current kinematic state and determines a short-horizon trajectory for the collaborator based on previously observed kinematic states of the collaborator towards the goal. The system also determines a likelihood that the collaborator will follow the possible trajectory based on the short-horizon trajectory, the goal, and the current kinematic state. The system also generates a movement instruction to control movement of the robot based on the likelihood that the collaborator will follow the possible trajectory.

For a kinematic modelled in a kinematics coordinate system by hingedly interconnected single axles, a method calculates a braking region possibly covered by at least one of the single axles connected to an origin of the kinematics coordinate system and at least one of the single axles moving relative to the origin. In the event of a braking process, for a point that is coupled to a single axle, at least one virtual end position of the point is determined from an initial position of the point, a vectorial speed of at least one single axle, and a minimum deceleration of at least one single axle. The braking region of the point is determined using an envelope of the initial position and the at least one virtual end position, the extent of the envelope being calculated from the initial position and the at least one virtual end position.

A method and a device monitors a working process, in which a workpiece is worked continuously along each of at least one working path during at least one working time period using a working tool arranged on a collaborative robot. The device includes a sensor apparatus for monitoring the environment of the collaborative robot and a detection device for detecting an object in a manipulation region around each working path of the collaborative robot. A working machine has a monitoring device of this type. The detection device is connected to a device for emitting an instruction signal within an instruction phase in the event that an object is detected in the manipulation region of a working path of the collaborative robot, so that the working process can be continued along the at least one working path without interruption.

A safety control module providing a boundary of a safety zone area that is associated with the human in a task oriented state that includes a largest possible area in which the human or an associated work object can extend when the human is standing in one location and performing the work task. The human movement and safety zone area location being used to develop a capture set area that includes at least one predictive future safety zone area location. Using the at least one predicted future safety zone area, establishing a travel path for moving the robot between locations without overlapping the capture set area.

In an embodiment, a method includes determining a given material to manipulate to achieve a goal state. The goal state can be one or more deformable or granular materials in a particular arrangement. The method further includes, for the given material, determining, a respective outcome for each of a plurality of candidate actions to manipulate the given material. The determining can be performed with a physics-based model, in one embodiment. The method further can include determining a given action of the candidate actions, where the outcome of the given action reaching the goal state is within at least one tolerance. The method further includes, based on a selected action of the given actions, generating a first motion plan for the selected action.

A computer implemented method for determining a configuration of a medical robotic arm, wherein the configuration comprises a pose of the robotic arm and a position of a base of the robotic arm, comprising the steps of: —acquiring treatment information data representing information about the treatment to be performed by use of the robotic arm; —acquiring patient position data representing the position of a patient to be treated; and —calculating the configuration from the treatment information data and the patient position data.

A robot optimization motion planning technique using a refined initial reference path. When a new path is to be computed using motion optimization, a candidate reference path is selected from storage which was previously computed and which has similar start and goal points and collision avoidance environment constraints to the new path. The candidate reference path is adjusted at all state points along its length to account for the difference between the start and goal points of the new path compared to those of the previously-computed path, to create the initial reference path. The initial reference path, adjusted to fit the start and goal points, is then used as a starting state for the motion optimization computation. By using an initial reference path which is similar to the final converged new path, the optimization computation converges more quickly than if a naïve initial reference path is used.

The arrangement is provided for monitoring state and sequence of movement in an aseptic work chamber of a containment standing in an installation room. At least one work glove projects into the work chamber, wherein the respective work glove is able to stretch up to a maximum grasping range in the three spatial axes in the work chamber. The arrangement comprises a tracking system, the recordings of which serve to continuously localize the at least one work glove in three dimensions and are stored in a computer unit. At least one three-dimensional or two-dimensional prohibited region, which may be adjoined by a warning region, is defined in the work chamber. Individual surface sections or the entire floor of the containment can be defined as a prohibited region. A prohibited region and possibly a warning region in front of this can be set up around machines which are installed in the work chamber and which constitute a danger for the operator. The coordinates of prohibited region and warning region are stored in the computer unit. The at least one work glove must not be used to intervene in the prohibited region and should not be used to intervene in the warning region.
