In the following, a method for synchronizing the motion sequences of at least two robots will be described. In accordance with one embodiment, the method comprises the following: During operation of a robot cell having at least two robots, a path parameter is regularly calculated for each of the at least two robots based on a current position of the respective robot and on a previously specified robot path of the respective robot. The path parameter represents the current position of the robot. Subsequently, a run-ahead limit is calculated for each robot based on the path parameters determined for the respective other robots. Based on the respective calculated run-ahead limit, the path speed of every robot can be adjusted.

A robot is described. The robot includes a propulsion system, a wireless interface, a memory device, and a processor configured to execute instructions stored in the memory device. The instructions, when executed by the processor, cause the processor to determine, based upon a communication received at the wireless interface, to perform a celebration associated with a trigger event that has occurred on a casino floor and in response to determining to perform the celebration, control the propulsion system to cause the robot to perform at least a portion of the celebration.

A robot interference checking motion planning technique using swept volume deformation. A rapidly-exploring random tree (RRT) algorithm generates random sample nodes between a start point and a goal point. Each sample node is evaluated by checking for robot-obstacle interference along a path segment to the node. If an interference exists along the path segment, a swept volume of the segment is used to identify a critical posture where the interference is greatest, and obstacle interference points are used to define a virtual force applied to the robot links to modify the path segment to alleviate the interference condition. A swept volume of the modified path segment is computed and evaluated. If the modified swept volume is collision-free and the modified path segment motion plan meets robot joint range criteria, the modified path segment and the sample node are added to the overall robot motion program.

A state machine controller to dynamically plan a robot's path. An industrial robot such as a multi-arm articulated robot operates in a workspace according to a program. A sensor or camera monitors the workspace and detects any object, such as a person, approaching or entering the workspace. The sensor provides input to the state machine controller, which includes states of; track current path, change speed, and replan path. When an object approaches or enters the workspace, the state machine determines if a transition to the change speed state is necessary. After reducing robot speed in the change speed state, the state machine can resume the original path and speed if the object has cleared the workspace, further reduce speed to zero if necessary to avoid a collision, or transition to the replan path state to compute a new path to the goal position which avoids the object in the workspace.

When a first condition that a time in which magnitude of a first detection force detected by a force detection unit is larger than a first force threshold value continued for a time longer than zero and shorter than a first time threshold value is satisfied in teaching, a movable unit is moved in a predetermined amount in a direction according to a direction of the first detection force. When a second condition that magnitude of a second detection force detected by the force detection unit is larger than a second force threshold value that is larger than the first force threshold value is satisfied during movement of an end effector, the movable unit is decelerated or stopped.

An operation instruction list including starting points and ending points of trajectories of a plurality of robot arms is generated (a trajectory definition data generation process). Order of generation of trajectories is determined in accordance with the operation instruction list (a generation order determination process). A trajectory of a specific robot arm included in the operation instruction list is generated in accordance with a starting point and an ending point such that the trajectory avoids obstacle spaces registered in the obstacle memory when trajectories of other robot arms are generated (a trajectory generation process).
