The present invention discloses a lifting mechanism mounted on a lifting device, wherein the lifting device includes a carrying unit. The lifting mechanism is disposed under the carrying unit, and comprises a driving assembly and a lifting assembly. The driving assembly includes an axle fixing part, a drive wheel and a power source, and the lifting assembly includes a screw nut and a screw rod. An upper end of the screw rod is fixedly connected to the carrying unit. When the lifting mechanism is traveling, each drive wheel is in contact with a base surface and moves the lifting device on the base surface; and when lifting, each drive wheel rotates on the base surface to drive the screw nut to rotate about a vertical axis relative to the carrying unit, to drive the screw rod to lift the carrying unit along the vertical direction.

The present disclosure relates to a position detection apparatus and a position detection method of a distribution object, a robot, a distribution apparatus, and a controller, and relates to the field of robots. The apparatus includes: a plurality of ranging sensors arranged on an end surface of a protrusion member of a robot facing a placement region of the distribution object, wherein the protrusion member is located on a chassis of the robot and each of the plurality of ranging sensors is configured to detect a distance between the ranging sensor and an end surface of the distribution object facing the plurality of ranging sensors; and a controller configured to determine that the distribution object has been located at a predetermined position above the chassis in a case where the distance detected by each of the plurality of ranging sensors is not greater than a first distance threshold.

A lifter device includes: a pole; a lifting member configured to be guided by the pole; a motor configured to generate power used for ascending and descending of the lifting member; a transmission mechanism configured to transmit the power of the motor to the lifting member; and a preventing member configured to prevent the descending of the lifting member when the power is not transmitted.

When an industrial vehicle encounters a geo-feature, one or more messages for conveyance on the industrial vehicle are determined based on a current operating state of the industrial vehicle and an expected operating condition associated with the encountered geo-feature. In an example implementation, the geo-feature can implement aisle control in a warehouse or similar environment to ensure that only authorized vehicles are permitted to enter the aisle. Here, authorization may be predicated upon an assigned task from a warehouse management system. In another example implementation, the industrial vehicle includes a display that provides a graphical representation of the geo-feature.
