This paper aims to design an unmanned trolley target search and adaptive charging system based on multimodal perception, so as to improve the autonomous navigation, target positioning and search ability of unmanned trolley in complex environment, and realize the autonomous management and supplement of energy. The paper first summarizes the principle of multimodal perception technology and its application in unmanned car, including various data fusion methods, such as vision, radar and acoustics. Subsequently, the target search system of the unmanned car is designed, through the feature extraction, identification algorithm and path planning strategy, to realize the efficient search and positioning of the target. At the same time, an adaptive charging system is built, which realizes the autonomous charging function of unmanned cars through energy state monitoring, identification and positioning of charging facilities, and the strategy of autonomous navigation and charging docking. In the experimental verification stage, this paper builds the hardware platform of unmanned car and designs the corresponding software system. The effectiveness and reliability of target search and adaptive charging system are verified through the indoor and outdoor environment. The experimental results show that the system can accurately identify the target, plan the reasonable path, and independently find the charging facility for charging when the energy is insufficient. This study not only enriches the research results in the field of unmanned vehicle technology, but also provides strong support for the application of unmanned vehicle in a complex environment. In the future, it will further optimize the system performance, expand the application field, and promote the sustainable development of unmanned car technology.
