  • Patent number: 11656628
    Abstract: Described herein are systems, devices, and methods for controlling a mobile cleaning robot to escape from a stuck state using a learned robot escape behavior model. The model is trained using reinforcement learning at a cloud-computing device or networked devices. A mobile cleaning robot comprises a drive system, a sensor circuit to collect sensor data associated with a detected stuck state, and a controller circuit that can receive the trained robot escape behavior model, and apply the sensor data associated with the detected stuck state to the trained robot escape behavior model to determine an escape policy. The drive system or one or more actuators of the mobile robot can remove the mobile robot from the stuck state according to the determined escape policy.

  • Publication number: 20230107675
    Abstract: A venting device comprises an air channel and a rotary venting rod, wherein: the air channel comprises a first end facing an outer surface of the rotary venting rod and a second end away from the rotary venting rod; the outer surface of the rotary venting rod is provided with a recessed venting slot in fluid communication with ambient air, about which the rotary venting rod may be rotated about a rotation axis extending longitudinally thereof to provide a vented state and a sealed state. In the vented state, at least a portion of the venting slot of the rotary venting rod is in fluid communication with the air channel and thereby brings the air channel into fluid communication with ambient air via the venting slot. In the sealed state, the venting slot of the rotary venting rod is not in fluid communication with the air channel and the first end of the air channel is sealed by the outer surface of the rotating vent rod. The venting device of the present invention is easy to manufacture and assemble.

    Abstract: An imaging device with a plurality of image sensing pixels and a plurality of event detection pixels is provided. The image sensing and event detection pixels can be provided as part of different arrays of pixels, or can be included within a common array of pixels. The event detection pixels are operated continuously to provide signals indicating the occurrence of events. In response to detecting an event, image sensing pixels are selectively operated. The selective operation of the image sensing pixels can include activation of image sensing pixels within one or more regions of interest, while image sensing pixels not included in any region of interest remain off. The selective operation of the image sensing pixels can include the selection of a frame rate applied across an array of mage sensing pixels, or within determined regions of interest.

  • Publication number: 20230008723
    Abstract: A sensor system with a plurality of sensors or sensor functions is provided. The sensors can include an event detection sensor, a time of flight sensor, and imaging sensor. The different sensors can be implemented on the same or different substrates. Accordingly, sensors with pixels having different or shared functions can be included in the sensor system. In operation, an event detection signal from an event detection sensor causes the operation of a time of flight sensor to be initiated. In response to the detection of an object within a critical range by the time of flight sensor, the imaging sensor is activated. The image sensing and event detection pixels can be provided as part of different arrays of pixels, or can be included within a common array of pixels.
