A modular drive train assembly is disclosed for the rail wheels of a railcar mover that provides a plurality of electric drive motors. Each electric drive motor may be connected to a gearbox and subsequently connected to a rail wheel. An automated control system may further control the power supplied to each of the electric drive motors such that the power supplied to each electric drive motor may be individually controlled to enhance the traction of each rail wheel. In addition, a plurality of sensors may monitor and communicate information from the electric drive motors to allow the control system to automatically control the power to each of the electric drive motors to enhance traction of the railcar mover.

A method for turning robots at an intersection of tracks. The robot moves in a first motion mode to reach a first position at the intersection. The robot turns over a corner of the intersection that includes continuous tracks connecting a vertical track and a horizontal track, whereby reaching a second position at the intersection. The robot moves in a second motion mode towards a designated direction.

Provided are a material transportation vehicle, a material carrying device, a material drying system and a control method, an electronic apparatus, a computer-readable storage medium, and a computer program product. The material transportation vehicle includes: a carrying base, and a push-pull assembly arranged on the carrying base. The push-pull assembly is configured to drive a material pallet for containing a material to move between a first position and a second position. The first position and the second position are staggered in a first direction, and the second position is located above the carrying base.

A travel unit travels in a curved section in an orientation in which a target wheel comes into contact with a target rail, a guide wheel comes into contact with a guide rail, and a non-target wheel does not come into contact with a non-target rail. The control unit changes the rotational speed of a first wheel and a second wheel in the curved section relative to the rotational speed of the first wheel and the second wheel in a straight section in accordance with the ratio of a second length, which is the length of the target rail along a travel path, to a first length, which is the length of the curved section along the travel path at a center portion in a widthwise direction of the travel path.
