The invention discloses a pesticide spraying system and a method based on a child-mother system. Crop protection is implemented by a child-mother system composed of a pesticide spraying robot and a route planning unmanned aerial vehicle (UAV). A UAV image acquisition module acquires a farmland image, and sends the farmland image to a UAV control module. The UAV control module generates an optimal pesticide spraying route according to the farmland image, and sends the optimal pesticide spraying route to a robot control module. After the robot control module makes the robot move to near a farmland area needing pesticide spraying according to the optimal pesticide spraying route, a robot image acquisition module acquires an image of crops around, identifies a part of crops needing pesticide spraying, and sends the part to the robot control module. The robot control module makes a mechanical arm move to the part of crops needing pesticide spraying, makes the nozzle aligned with the part of crops needing pesticide spraying and starts spraying pesticide. Through intelligent route planning by the UAV, the consumption of pesticide, power and the like in the working process of the robot is minimized.

The invention relates to an automatic transverse level-adjusting mechanism for a vehicle chassis, which belongs to a vehicle travelling system. The automatic transverse level-adjusting mechanism comprises a carriage, a combined rigid body thereof, balancing rods, left connecting rods, right connecting rods, left supporting rods, right supporting rods, left axles, right axles, a chassis, left wheels and right wheels. As the vehicle chassis travels and operates, the wheels are in contact with the ground for bearing, the left supporting rods and the right supporting rods respectively move in a manner relative to the carriage, so that the balancing rods make a certain angle with the carriage, and thereby therefore the level of the chassis is transversely and automatically adjusted. As the vehicle chassis travels and operates on the flat ground or the cross slope, the level of the chassis can always be self-adaptively and transversely adjusted, and thereby therefore the requirements of the crop protection, harvest, transportation and other operation tasks of the agricultural power chassis on a hilly land can be met.
