In an embodiment, a mobile robotic device includes a mobile base and a mounting column fixed to the mobile base. The robotic device further includes a seven-degree-of-freedom (7DOF) robotic arm, including a rotatable joint that enables rotation of the 7DOF robotic arm relative to the mounting column. The robotic device additionally includes a perception housing comprising at least one sensor, where the mounting column, the rotatable joint of the 7DOF arm, and the perception housing are arranged in a stacked tower such that the rotatable joint of the 7DOF arm is above the mounting column and below the perception housing.

A mobile robotic device includes a mobile base and a mast fixed relative to the mobile base. The mast includes a carved-out portion. The mobile robotic device further includes a three-dimensional (3D) lidar sensor mounted in the carved-out portion of the mast and fixed relative to the mast such that a vertical field of view of the 3D lidar sensor is angled downward toward an are in front of the mobile robotic device.

The present disclosure relates to robot technology, and particularly to a method and a robot for identifying charging station. The method includes: first, obtaining scanning data produced by a radar of the robot; then, determining whether an arc-shaped object exists in a scanning range of the radar of the robot based on the scanning data; finally, in response to determining that the arc-shaped object exists in the scanning range of the robot, determining that the arc-shaped object is a charging station. Compared with the prior art, the present disclosure substitutes the arc identification for the conventional concave-convex structure identification. Since the surface of the arc is relatively smooth, the data jumps at the intersection of the cross-section will not occur, hence the accuracy of charging station identification can be greatly improved.

There is provided a configuration that can prevent malfunction in bus communication even when a radio signal transmitted from a transmitter of an apparatus is received with a receiver of the same apparatus. A logic circuit outputs logic 1 to a transmitter in a case where logic 0 is input from a receiver to the logic circuit and a low-level logic signal is input from a processor to the logic circuit. The logic circuit outputs the low-level logic signal to the processor in a case where the logic 1 is input from the receiver and a radio signal received with the receiver is a radio signal transmitted from a communication counterpart. The logic circuit outputs a high-level logic signal to the processor in a case where the logic 1 is input from the receiver and a radio signal received with the receiver is a radio signal transmitted from the transmitter.
