An autonomous coverage robot detection system includes an emitter configured to emit a directed beam, a detector configured to detect the directed beam and a controller configured to direct the robot in response to a signal detected by the detector. In some examples, the detection system detects a stasis condition of the robot. In some examples, the detection system detects a wall and can follow the wall in response to the detected signal.

An outdoor treatment system has an autonomous mobile outdoor treatment robot and a sensor and control device. The robot has a chassis and a contact element. The chassis executes a travelling movement in a direction of travel. The contact element executes an avoiding movement in an avoiding direction as a result of the travelling movement and contact between an obstacle and a lower contact point below a height limit, and executes a detection movement in a detection direction as a result of the travelling movement and contact between an obstacle and an upper contact point at or above the height limit. The contact element is mounted to move with respect to the chassis. The avoiding direction and the detection direction are different. The sensor and control device detects the detection movement and controls a robot protective function, and does not detect or evaluate the avoiding movement.

The present disclosure provides an anti-collision device and a robot. The anti-collision device has a first connecting member, a working structure and a first elastic member, the first connecting member is fixedly connected to a robot body, the working structure is arranged on a side of the first connecting member away from the robot body, the first elastic member is located between the first connecting member and the working structure, and the first elastic member is deformed when the working structure is impacted.

A device and a method for performing control to change a flexible virtual bumper for maintaining a space between a mobile object and an obstacle to be equal to or larger than a predetermined distance are enabled. A data processing unit that executes control to change the flexible virtual bumper for maintaining the space between the mobile object and the obstacle to be equal to or larger than the predetermined distance, and a drive unit that drives the mobile object in such a way that no obstacle enters the flexible virtual bumper are included. The data processing unit executes control to change the flexible virtual bumper at least either in size or shape. For each one of a plurality of travel route candidates for the mobile object, the data processing unit executes a simulation of changing the bumper size in such a way that no obstacle enters the flexible virtual bumper, and selects a safe travel route.

An automatic feeding system includes an autonomously moveable feeding device for feeding animals. The feeding device includes a feed container for accommodating feed, a feed dispensing device for dispensing feed from the teed container, and a safety device suitable for halting the autonomously moveable feeding device in case of collision with an obstacle. The safety device includes a bumper for establishing a first contact with such an obstacle. The bumper defines an outer safety contour of the autonomously moveable feeding device. The safety device further includes a partition opener configured to open a partition provided in a door opening for enabling the autonomously moveable feeding device to pass through the door opening. The door opening provided with partition may be provided in a barn for housing animals. The opening device is provided separately and independently from and is not directly, connected to the safety device. In this way, the partition opener acts independently from and does not affect the safety device.

A robot is described herein comprising high fidelity sensor control (e.g., via joystick or other data rich sensors) for robotic cleaning and navigation strategies. The robot may be sized or dimensioned for maneuvering for cleaning, disinfecting, or otherwise improving a physical environment (e.g., living spaces, office spaces, or the like), especially those having narrow or varied spaces created by obstacles within the physical environment. The cleaning robot as described herein provide solutions for overcoming problems that arise from cleaning target areas or environments that have typically been hard for conventional robots to clean, fit, and/or maneuver within.

A method of instance segmentation in an image and a system for instance segmentation of images. The method includes identifying, with a processor, a starting pixel associated with an object in an image, the image having a plurality of rows of pixels, the starting pixel located in a row of the plurality of rows; identifying, with the processor, at least one pixel located in an adjacent row to the row in which the starting pixel is located, the at least one pixel being part of the same object as the starting pixel; iterating the previous two identification steps using the at least one identified adjacent row pixel as a start pixel for the next iteration; and connecting, with the processor, the at least one identified adjacent row pixels to form polylines representing the object.

Disclosed is a cleaning robot including: a driving unit configured to move the cleaning robot; an obstacle sensor configured to sense an obstacle; and a controller configured to reduce, if a distance between the cleaning robot and the obstacle is shorter than or equal to a reference distance, a driving speed of the cleaning robot so that the driving speed of the cleaning robot is lower than a shock absorbing speed when the cleaning robot contacts the obstacle.
