Abstract: A self-propelled platform for monitoring field crop phenotype is provided. The monitoring platform includes a traveling and steering mechanism, wheel track and ground clearance adjustment devices, damping devices, and a case. The traveling and steering mechanism includes wheel side motors, wheels, and torque motors. The wheels are connected to respective upright posts of the platform through respective rigid independent suspensions. Each upright post is of sleeve structure and includes an upper sleeve and a lower sleeve. A corresponding damping device is connected between the upper sleeve and the lower sleeve. The wheel track and ground clearance adjustment devices are configured for adjusting the height of the case and the tracks between the wheels. The lower ends of the wheel track and ground clearance adjustment devices are rotatably connected to respective upright posts, and the upper ends are rotatably connected to the case.

Abstract: This disclosure can provide a display device, including a controller configured for determining whether an application interface of a current application supports a screen orientation after rotation; if so, outputting a rotation command so that a rotating component can drive the screen to rotate based on the rotation command; and if not, controlling the screen to display a prompt message, so that a user can determine whether to continue to control the screen to rotate via the prompt message if needed.

Abstract: Disclosed are a display apparatus and an interface display method. The display apparatus includes a display, a rotating assembly in connection with the display and configured to drive the display to rotate to a rotation station, and a controller in communication with the display and the rotating assembly.

Abstract: Provided are a display apparatus and display method for the display apparatus with a rotatable display. A controller thereof is configured to, during a power-off state or standby state of the display apparatus, in response to an instruction for starting the display apparatus, detect a current rotation state of the rotatable display; in response to the rotatable display being in the horizontal state, control the display to present an animation for the starting of the display apparatus corresponding to the horizontal state; and in response to the rotatable display being in the portrait state, control the display to present an animation for the starting of the display apparatus corresponding to the portrait state.
