Abstract: In some implementations, a robotic device may receive, from a first light detection and ranging (LIDAR) sensor and a second LIDAR sensor, calibration data associated with a physical environment of a robotic arm of the robotic device. The robotic device may determine, based on the calibration data, a configuration of a boundary for the robotic arm. The robotic device may position, relative to the robotic arm, the first LIDAR sensor at a first position and the second LIDAR sensor at a second position to sense an activity within the boundary. The robotic device may monitor the boundary based on first sensor data from the first LIDAR sensor and second sensor data from the second LIDAR sensor. The robotic device may disable, based on the first sensor data or the second sensor data indicating the activity associated with the boundary, the robotic arm from moving within the boundary.
