  • Publication number: 20220118621
    Abstract: Disclosed herein are systems, devices, and methods for improving the safety of a robot. The safety system may determine a safety envelope of a robot based on a planned movement of the robot and based on state information about a load carried by a robot. The state information may include a dynamic status of the load. The safety system may also determine a safety risk based on a detected object with respect to the safety envelope. The safety system may also generate a mitigating action to the planned movement if the safety risk exceeds a threshold value.

  • Publication number: 20220111532
    Abstract: A device may include a processor. The processor may receive sensor data representative of an environment comprising a robot. The processor may extract features from the sensor data to generate an extracted feature set indicating an observation of the robot within the environment. The processor may generate a feature set indicating an expected observation of the robot within the environment based on pre-defined parameters of the robot. The processor may determine a difference between the observation and the expected observation of the robot. The processor may determine a systemic failure based on the difference between the observation and the expected observation of the robot exceeding a threshold value. The processor may instruct the robot to transition to a non-operative state responsive to the systemic failure being determined.

  • Publication number: 20220105633
    Abstract: Disclosed herein are systems, devices, and methods for efficiently checking the integrity of a robot system. The integrity-checking system may generate a predefined motion instruction for a robot, where the predefined motion instruction instructs the robot to perform a random movement at a test time. The random movement may be associated with an expected observation at the test time. The integrity-checking system may also determine a systematic failure based on a difference between the expected observation and a current observation of the robot at the test time. The current observation may be determined from received sensor data, and if the integrity-checking system detects a failure, it may stop the robot's motion or other mitigating instructions.
