A robot cleaner having a main body, a driving unit for moving the main body, a sensing unit for sensing information related to an obstacle, and a controller for controlling the driving unit to prevent collision of the main body with the obstacle. The controller controls the driving unit to reverse the main body with respect to the obstacle so as to prevent the main body from contacting the obstacle based on a distance between the main body and the obstacle.

An environment map includes cells, each of which is assigned to portions of the environment of a vehicle and each of which is assigned an obstacle probability that represents the probability that the corresponding portion of the environment is occupied by an obstacle. The vehicle has at least two environment sensors, each of which is designed to provide measurement data on the occupancy of a region of the environment by an obstacle, referred to as an obstacle region, in the respective detection region of the sensor. The measurement data describes obstacle regions which extend over multiple portions of the environment, and the detection regions of the environment sensors at most partly overlap. A method for providing the environment map for the vehicle has the following steps: receiving the measurement data from the at least two environment sensors, the measurement data of a first environment sensor identifying an obstacle region; determining occupancy probabilities for the portions of the environment covered by the identified obstacle region of the measurement data of the first environment sensor on the basis of the measurement data of at least one other environment sensor, wherein an occupancy probability for a portion indicates the probability that the corresponding portion of the environment is occupied by an obstacle; and updating the obstacle probability of the environmental map for at least the portions for which the occupancy probability has been determined.

An object detection device of the present disclosure includes three reception units for receiving reflected waves resulting from reflection of a transmission wave by an object within a detection range, and a determination unit for determining presence or absence of an object to be avoided based on outputs of the three reception units. The determination unit calculates first coordinates and second coordinates at which an object is estimated to be present, based on reception times from when a transmission wave is transmitted until reflected waves are received by the three reception units, and determines whether or not the object needs to be avoided, based on a distance between the first coordinates and the second coordinates.

A system and method for participating in a multi-USV performance in three-dimensional space. The USV can include: a computer processor; a sensory device configured to detect live sensory information relative to a second USV participating in the performance in proximity to the USV; and a spatial control module executing on the computer processor and configured to enable the computer processor to: (i) receive instructions for performing a pre-determined sequence of spatial maneuvers of the performance; (ii) begin execution of the pre-determined sequence of spatial maneuvers according to the instructions; (iii) identify a modified sequence of spatial maneuvers calculated based on the live sensory information from the sensory device; (iv) halt execution of the pre-determined sequence of spatial maneuvers; and/or (v) execute the modified sequence of spatial maneuvers.

A proximity device, a computer-implemented method, and proximity system are described. Generally, the proximity device can be wearable or non-wearable. A wearable proximity device is configured to be worn by a user. As the user moves within a physical environment, the wearable proximity devices monitors the user's proximity to objects. Proximity indications are accordingly generated and presented to the user. A non-wearable proximity device is configured to monitor the user's proximity relative to a perimeter of an area. If the user approaches or overruns the perimeter, a proximity indication is generated and presented to the user.

The present disclosure describes a system, device, and method for assisting a user to avoid contacting surfaces with their mobile device. An environment is sensed with one or more electronic sensors. The sensor readings are analyzed. Information is then provided to a user based on the analyzed sensor readings. The sensors may be configured so their sensor cones cross at a midpoint. Readings from the sensor(s) may be grouped according detection zone(s) corresponding to one or more areas about a mobile device. A computing module may control a feedback module according to detection zone readings. The feedback module may comprise an indicator for each detection zone. The indicator may be a vibration motor. The indicator may be a light. The computing module may set the colour of a light and/or control the vibrations based on the proximity of surfaces detected within the corresponding detection zone.
