A novel navigation assistant method for substation inspection robot based on multisensory information fusion.
Review in Journal of advanced research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionDue to the complex environment of the substation, the inspection work of the substation becomes time-consuming and laborious. As a result, the substation inspection robot has gradually become a hot research point.
objectivesAt present, the mainstream intelligent inspection robots for substations use high-precision LiDAR sensors for navigation, which has high navigation accuracy but cannot identify the types of obstacles and the road contour boundary, seriously affecting the inspection performance and efficiency. Meanwhile, the high-precision 3D laser radar is too expensive to afford. In order to solve these problems, a novel navigation assistant method is proposed in this paper, which is based on multisensory information fusion.
methodsAsynchronous information matching with multiple sensors was used to match the information collected by different sensors to deal with the time asynchrony. To express the height of obstacles, 2D laser radar was applied to create 3D imaging by being combined with inertial measurement unit (IMU). For perceiving and under-standing the substation environment independently by the inspection robot, ENet was given over to segment color point cloud maps, which was built by introducing optical sensor data. The method was implemented based on the ROS system and transplanted to embedded platform of the inspection robot.
resultFinally, experimental results show that, compared with VLP-32C 3D laser radar sensors, the data volume of navigation assistance module had reduced by 95%. Meanwhile, after training the ENet network, the mean average accuracy value had achieved 86%, which meets the needs of practical engineering applications.
conclusionIn addition, the inspection robot equipped with the navigation assistance module is successfully tested in multiple substations, which shows that the robot can not only identify the road contour and the type of obstacles on the way, but also reduce the amount of data and the cost of hardware.
