An unmanned aerial vehicle (UAV) autonomously perching on a curved surface from a starting position is provided. The UAV includes: a 3D depth camera configured to capture and output 3D point clouds of scenes from the UAV including the curved surface; a 2D LIDAR system configured to capture and output 2D slices of the scenes; and a control circuit. The control circuit is configured to: control the depth camera and the LIDAR system to capture the 3D point clouds and the 2D slices, respectively, of the scenes; input the captured 3D point clouds from the depth camera and the captured 2D slices from the LIDAR system; autonomously detect and localize the curved surface using the captured 3D point clouds and 2D slices; and autonomously direct the UAV from the starting position to a landing position on the curved surface based on the autonomous detection and localization of the curved surface.

An omnidirectional moving device is provided with a vehicle chassis, a vehicle body, a universal coupling, and an attitude stabilizing system. In the vehicle chassis, a plurality of wheels that are capable of moving omnidirectionally are provided. The vehicle body is mounted on the vehicle chassis. The universal coupling connects the vehicle chassis to the vehicle body, and the attitude of the vehicle body relative to the vehicle chassis can be changed via this universal coupling. The attitude stabilizing system causes the vehicle chassis to move in a direction that corresponds to a change in the attitude of the vehicle body, and maintains the attitude stability of the vehicle body.

A mower deck can include roller assemblies that prolong the life of bearings by more evenly distributing the roller's load to the bearings. The roller assembly can include a roller that is secured between opposing bearings via a tapered shaft of the roller and a correspondingly tapered collar that is housed within the corresponding bearing. The interface between the tapered shaft and the tapered collar causes the collar to be secured snugly within the bearing while also providing even distribution of the roller's load to the bearing.

A paint robot having a sprayer that is substantially fixed in an orientation in which the spray fan is perpendicular to the wall surface may be ineffective at painting portions of a wall that are not substantially flat (e.g., flat). These portions may include one or more protrusions and/or recesses such as, for example: (1) a chair rail or other suitable piece of molding; (2) one or more window ledges and/or sills; (3) one or more exit signs; (4) one or more thermostats; (5) etc. As such, it may be desirable to incorporate an articulating spray head (e.g., a pivoting sprayer) into an automated mobile painting system in order to, for example, paint the upper and lower portions of the wall by angling the paint sprayer to paint over and/or under the various protrusions which may exist on the wall as discussed above.

An unmanned aerial vehicle (UAV) for landing and perching on a curved ferromagnetic surface is provided. The UAV includes a plurality of articulated legs. Each articulated leg includes: a magnet configured to magnetically attach to the curved ferromagnetic surface; and a magnetic foot for housing the magnet and configured to magnetically articulate towards and attach to the curved ferromagnetic surface using the magnet in a perpendicular orientation with respect to the curved ferromagnetic surface, in response to the UAV approaching the curved ferromagnetic surface, in order to land the UAV on the curved ferromagnetic surface and for the UAV to perch on the curved ferromagnetic surface after the landing. The magnetic foot is configured to remain magnetically attached to the curved ferromagnetic surface while the UAV is perched on the curved ferromagnetic surface.

Disclosed are a wheel for a lawn mower robot and the lawn mower robot including the same. A wheel for a lawn mower robot according to an embodiment of the present disclosure has a structure in which grass seeds can be discharged during a rotation of the wheel.

Accordingly, grass seeds are sown as the lawn mower robot travels while performing a lawn mowing task. Therefore, a task of mowing the lawn and a task of sowing seeds can be performed in a unified manner. In other words, the lawn can be managed more efficiently.
