The invention belongs to the technical field of unmanned aerial vehicles, and particularly discloses an unmanned transportation and delivery route planning method and device based on multiple factors, and the method comprises the steps: determining the task demand information of a transportation and delivery task; performing unmanned aerial vehicle matching according to the task demand information to obtain an unmanned aerial vehicle score, and selecting a target unmanned aerial vehicle according to the unmanned aerial vehicle score to execute the transportation and delivery task; obtaining a target path by using a path planning algorithm, and scoring the target path to obtain a target path score; and determining an environmental factor score according to the path voyage and the path points, and performing weighted calculation on the unmanned aerial vehicle score, the target path score and the environmental factor score to obtain a comprehensive score of the target path for reference by a decision maker. According to the invention, the accuracy and efficiency of route planning can be improved.

The present invention discloses a method and system for path planning of an article sorting robot arm based on vision, and relates to the technical field of robot arm path planning. After the light source is automatically controlled, image data in the sorting area is collected, and after the target image is screened out, the detected objects are divided into obstacles and objects to be sorted, and marked on the real-time environmental map of the sorting area. After planning and acquiring the grasping path, the robot arm of the sorting robot grasps the objects to be sorted according to the target path, and the grasping scene data is used as feedback to optimize the movement speed and grasping path of the robot arm of the sorting robot; the grasping feedback value and feedback threshold are constructed from the grasping feedback data, and the corresponding sorting processing strategy is adopted according to the relationship between the grasping feedback value and the feedback threshold. The efficiency in the actual grasping process is improved, invalid grasping or inefficient grasping is reduced, and the grasping feedback effect of the robot arm is improved.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for training a policy neural network for use in controlling an agent using relative variational intrinsic control. In one aspect, a method includes selecting a skill from a set of skills, generating a trajectory by controlling an agent using a policy neural network while the policy neural network is conditioned on the selected skill, processing an initial observation and a last observation using a relative discriminator neural network to generate a relative score, processing the last observation using an absolute discriminator neural network to generate an absolute score, generating a reward for the trajectory as a function of the absolute score corresponding to the selected skill and the relative score corresponding to the selected skill, and training the policy neural network based on the reward for the trajectory.

The utility model relates to a sample multiple dilution device for quantitative detection. The problems that in the prior art, when samples with large dilution ratios are diluted, mutual aerosol pollution is prone to occurring between the samples, and confusion is prone to occurring between the samples with different dilution ratios are solved. The dilution device comprises a dilution device body and a rotary cover component, the dilution device body comprises a plate frame, a plurality of liquid containing wells are arranged on the plate frame, and liquid delivery channels used for being communicated with the liquid containing wells are arranged on the plate frame; the rotating cover component comprises a rotating cover body arranged in the liquid containing well, a rotating handle is arranged on the rotating cover body, and a liquid delivery opening capable of being communicated with the liquid delivery channel is formed in the side wall of the rotating cover body. The device has the advantages that the device is convenient to operate, cross contamination and confusion among different samples are effectively avoided, and the dilution accuracy is high.
