Abstract: An automatic lawn compactor includes a case, a battery pack, a controller, a driving device and a trampling device. The battery pack is disposed in the case. The battery pack is configured to supply electrical power to the driving device. The controller is connected with the driving device for controlling the driving device. The driving device is configured to drive the automatic lawn compactor to move autonomously on the lawn. The grass on the lawn is trampled by the trampling device as the automatic lawn compactor moves on the lawn. Through regular trampling the lawn, the grass on the lawn is kept at a certain height to realize the beauty and ornamentality of the lawn. The automatic lawn compactor overcomes the shortcomings of large noise, the difficulty of cleaning up the grass, and the hard work by the existing lawn compactors.

Abstract: An autonomous driving control system comprises a main controller, a backup controller, main execution apparatuses and backup execution apparatuses. The backup controller is configured to decompose, when receiving a main control instruction from the main controller, the main control instruction to obtain backup control instructions corresponding to the backup execution apparatuses respectively, and send the backup control instructions to the backup execution apparatuses correspondingly; and the control system is configured to control, when detecting that an abnormality occurs in any one device of the main execution apparatuses, the backup execution apparatus corresponding to the device in which the abnormality has occurred to execute a corresponding backup control instruction. The system can solve the problem that an autonomous driving control system cannot operate normally when any controller or actuation mechanism fails at a single point.

Abstract: A transmission and a power system for use in a hybrid vehicle. A first ring gear or a first planetary frame is drivingly connected with an output gear of the transmission to serve as an output member, when either the first ring gear or the first planetary frame is drivingly connected with the output gear, the other one is connected with a casing of the transmission via a brake. A second clutch is configured as: when the brake is disengaged, the second clutch is engaged to make the rotational speed of the output member equal to the rotational speed of an input shaft. The transmission and the power system are structurally compact, work steadily, and effectively increase the acceleration performance of the hybrid vehicle.

Abstract: An unmanned aerial vehicle (UAV) configured to be carried on a vehicle and a method and a system for holding umbrella using the UAV are disclosed.
