A motor vehicle having a vehicle body with a passenger compartment, a chassis supporting the vehicle body, a vehicle axle which can be driven by a drive device, and a seat device which is arranged inside the passenger compartment and is rotatable relative to the passenger compartment about an axis of rotation. The chassis supporting the vehicle body has only one vehicle axle, about the axis of which, the vehicle body with the passenger compartment and the seat device arranged inside the passenger compartment are rotatable relative to each other.

A self-propelled device can include at least a wireless interface, a housing, a propulsion mechanism, and a camera. Using the camera, the self-propelled device can generate a video feed and transmit the video feed to a controller device via the wireless interface. The self-propelled device can receive an input from the controller device indicating an object or location in the video feed. In response to the input, the self-propelled device can initiate an autonomous mode to autonomously operate the propulsion mechanism to propel the self-propelled device towards the object or location indicated in the video feed.

A self-propelled device includes a spherical housing and an internal drive system. The self-propelled device can further include an internal structure having a magnet holder that holds a first set of magnets and an external accessory comprising a second set of magnets to magnetically interact, through the spherical housing, with the first set magnets

A motorized humanoid robot having a positioning axis extending along a reference axis in a reference position and capable of moving on a horizontal plane, comprises a first and a second wheel in contact with the horizontal plane. The robot comprises a base having a warped surface which, in a vertical plane passing through the center of the wheels, extends on either side of each of the wheels, the warped surface being able to form, at any point of the warped surface, a first point of contact with the horizontal plane, defining, for any first point of contact, a center of rotation, and wherein the robot is configured in such a way that the center of rotation and the center of gravity of the robot are offset so as to generate a torque tending to return the robot from any position in which its positioning axis forms a non-zero angle with the reference axis to the reference position.

A self-propelled device is disclosed that includes a center of mass drive system. The self-propelled device includes a substantially cylindrical body and wheels, with each wheel having a diameter substantially equivalent to the body. The self-propelled device may further include an internal drive system with a center of mass below a rotational axis of the wheels. Operation and maneuvering of the self-propelled device may be performed via active displacement of the center of mass.

A walking mechanism for driving a machine body includes a walking wheel group having a plurality of walking wheels attached to the machine body, with two front and two rear wheels relative to a traveling direction. The machine body has two sides with a pair of one of the front wheels and a one of the rear wheels being respectively located on each of the sides and driven to rotate synchronously. Each walking wheel includes an auto tire casing with a tread outer side having a tread pattern distributed along a circumferential direction of the auto tire casing. The tread pattern is configured as a plurality of tread ribs with a respective tread groove formed between each adjacent pair of the tread ribs, the tread pattern radiating outward from an axial center of the walking wheel. A related robot and self-walking mower are also disclosed.
