The system comprises also at least one area detecting laser scanner arranged to detect humans at least in the low grade safety area around the high grade safety area. Furthermore, in the system according to the invention the control unit is arranged to control the at least one laser scanner to form an at least one virtual door in to the at least one laser scanning wall through which a human detected in the low grade safety area by the area detecting laser scanner can safely enter from the low grade safety area to the high grade safety area. The invention relates also to a method for forming a controlled safety area for a manipulator. | 2022-05-19 |
20220152832 | AUTOMATED STORAGE OPTIMIZATION AND STACKABLE PALLETS - Examples described herein provide a system that includes a pallet. The pallet includes a base and a support member extending from the base. The support member is configured to support another pallet upwardly adjacent to and spaced from goods on the pallet. The support member is configured with an indexing feature. The system further includes a robot including a pallet engaging member configured to engage the pallet at the indexing feature on the support member. The system further includes a control system to control the robot based on a task. | 2022-05-19 |
20220152833 | EFFICIENT ROBOT CONTROL BASED ON INPUTS FROM REMOTE CLIENT DEVICES - Utilization of user interface inputs, from remote client devices, in controlling robot(s) in an environment. Implementations relate to generating training instances based on object manipulation parameters, defined by instances of user interface input(s), and training machine learning model(s) to predict the object manipulation parameter(s). Those implementations can subsequently utilize the trained machine learning model(s) to reduce a quantity of instances that input(s) from remote client device(s) are solicited in performing a given set of robotic manipulations and/or to reduce the extent of input(s) from remote client device(s) in performing a given set of robotic operations. Implementations are additionally or alternatively related to mitigating idle time of robot(s) through the utilization of vision data that captures object(s), to be manipulated by a robot, prior to the object(s) being transported to a robot workspace within which the robot can reach and manipulate the object. | 2022-05-19 |
