Abstract: The disclosure relates to systems and methods for ensuring human safety in a workspace shared with a robot or other dangerous machinery. The system includes one or more sensors arranged to monitor the workspace. Data from each of the sensors is acquired and analyzed to determine the positioning and spatial relationship between the human and machine, along with any respective objects that either or both may be carrying as they each move throughout the workspace. The captured data is analyzed to mitigate potential collisions between the human and the machine in the workspace, including potential collisions that may be caused by the respective objects carried by the human or machine.

Abstract: A system and method are described herein for controlling optical power provided to one or more laser projectors of an image capture device, such as a stereo camera, for improving depth image acquisition and quality while adhering to eye safety standards based on laser emissions. The system includes one or more laser projectors operable to emit a laser dot pattern onto a scene, and image capture devices operable to capture images from the scene including the laser dot pattern. The images are analyzed to acquire depth information for objects in the scene, and the depth information is used to modulate the optical power of the laser projectors based on the distance to the object relative to the image capture device.

Abstract: The disclosure relates to systems and methods for determining and adjusting an allowable maximum speed of a machine for movement in a workspace. One or more sensors monitoring the workspace are arranged to obtain a three-dimensional view of the workspace. Raw data from each of the sensors is acquired and analyzed to determine the positioning and spatial relationship between the human and machine as both move throughout the workspace. This captured data is analyzed to determine a safety protocol that includes a maximum allowable speed for each of various axes of movements for the machine, wherein the safety protocol decreases the maximum allowable speed of the machine only along the one or more axes of movement where the movement of the machine approaches the human.

Abstract: The disclosure relates to a system and method for verifying robot data that is used by a safety system monitoring a workspace shared by a human and robot. One or more sensors monitoring the workspace are arranged to obtain a three-dimensional view of the workspace. Raw data from each of the sensors is acquired and analyzed to determine the positioning and spatial relationship between the human and robot as both move throughout the workspace. This captured data is compared to the positional data obtained from the robot to assess whether discrepancies exist between the data sets. If the information from the sensors does not sufficiently match the data from the robot, then a signal from the system may be sent to deactivate the robot and prevent potential injury to the human.

Abstract: It is disclosed a device for determining an axis joining origins of two reference systems of a rigid body. The device comprises first and a second inertial sensors constrained to the rigid body and for defining the first and second reference systems. The device comprises a processing unit comprising an acquiring module of first data of angular velocities and second data of linear accelerations of the rigid body, a first module for calculating third data of angular accelerations of the rigid body as a function of the first acquired data, a second module for calculating a relative orientation between the first and the second reference system as a function of the first data, a third module for calculating a vector joining origins of the first and second reference system, wherein the primary direction of the primary vector is representative of the axis joining the origins of the two reference systems.
