摘要:
A robot simulator includes a storage device that stores model information related to the robot and an obstacle in the vicinity of the robot, and an acquisition device that obtains first input information defining a start position and an end position of operation of the robot. A processing device generates a path for moving the distal end portion of the robot from the start position to the end position while avoiding collisions between the robot and the obstacle based on the first input information and the model information. The processing device also generates image data including an illustration of the obstacle and an index indicating a via-point of the path.

A programming device receives a number of local coordinate systems from a user. Each local coordinate system is referenced directly or via at least one other local coordinate system to a global machine coordinate system of a motion-controlled machine. The programming device receives from the user, in each case with reference to one of the local coordinate systems, a number of positions to be approached by the end effector and/or a number of obstacles to be bypassed by the end effector. The programming device determines, with reference to the positions to be approached received from the user and the obstacles received from the user in the global machine coordinate system, the path to be traveled by the end effector The programming device stores the path to be traveled by the end effector as a first file so that it can be retrieved again at a later time.

An offline teaching device has a calculation unit which calculates a second position of a second tool on a work line which is separated by a predetermined distance from a first position of a first tool on the work line, calculates a workpiece position where the first tool in the first position contacts or adjoins the workpiece, and calculates a workpiece position and posture such that the second tool in the second position contacts or adjoins the workpiece by changing the posture of the workpiece from the workpiece position with respect to the first tool, while maintaining the work posture of the first tool, and has a generation unit which generates a robot teaching position based on the position and posture of the workpiece and the holding position of the workpiece, and generates a program such that the first tool and the second tool pass along the work line.

A method of commanding a remote vehicle includes executing a command on a controller of the remote vehicle based on a kinodynamic fixed depth motion planning algorithm to use incremental feedback from evaluators to select a best feasible action. The method also includes determining servo commands corresponding to the best feasible action for one or more actuators of a drive system or a manipulation system of the remote vehicle and commanding the one or more actuators of the remote vehicle based on the servo commands. The best feasible action includes actions within a fixed time horizon of several seconds from a current time each time a feasible action is selected.

In a multiaxial robot, a path along which the end effector of the robot moves in the shortest time duration is generated. The robot includes a first link and a second link positioned closer to an end effector than the first link. Start and end points are specified, and velocity patterns are generated for joints driving the first and second links based on the specified start end points. The velocity patterns enable a movement of the second link to cause i) a reaction for increasing an acceleration force generated by the first joint when the end effector is started to be moved from the start point toward the end point, and ii) a reaction for increasing a deceleration force generated by the first joint when the end effector is stopping to the end point.

The optimization of cost function representing a movement of the mass by the multi-motor control system from an initial point to a final point is subject to non-convex constraints due to avoidance of a region of the obstacle located between the initial point and the final point. Hence, the method determines a union of convex regions connecting the initial point with the final point, such that each convex region does not intersect the region of the obstacle, a convex constraint for each convex region and a set of switching times when the trajectory crosses boundaries of the convex regions. The method optimizes the cost function by jointly updating the positions and the set of switching times to produce an optimal trajectory of the movement. The optimizing is subject to the set of convex constraints applied independently for each corresponding convex region.

A method of automatic path planning for at least one robot within a confined configuration space, the robot including an arm having a plurality of joints and an end effector coupled to the arm. The method includes entering a plurality of process points into a computer, each process point being a location wherein the arm is to be positioned to perform a task, calculating one or more inverse kinematic solutions for each process point, clustering the inverse kinematic solutions into a set of clusters, and generating collision free paths between the clusters in the confined configuration space.
摘要:
A method of generating a command for a remote vehicle controller by taking in goals and constraints compiled from behavior inputs and action models, and controlling resources by producing low-level actuator commands that realize goals expressed by the behaviors. The method comprises: executing a command based on a kinodynamic fixed depth motion planning (KFDMP) algorithm to plan paths with longer time horizons and to use incremental feedback from evaluators to select a best feasible course of action; and feeding the selected best feasible course of action as servo commands to a drive system or a manipulation system of the remote vehicle controller. The selected best feasible course of action comprises goal-achieving actions within a fixed time horizon of several seconds from the current time each time a course of action is selected.
摘要:
A path planning apparatus of a robot smoothes a motion path while satisfying a constraint. In a configuration space where a manipulator of a robot performs a task, a Rapidly-exploring Random Tree (RRT) path which extends from a start point and reaches a goal point may be smoothed while satisfying a constraint to generate a stable motion path. Accordingly, path planning performance is improved and an optimal path satisfying a kinematic constraint may be rapidly obtained.
