本项目旨在研究空间信息网络中多节点同时激光高速信息传输技术，开展空—地、空—空链路激光通信外场演示验证试验。首先提出多节点同时激光通信的总体方案，接着开展轻小型化、低功耗激光通信光端机设计、环境适应性与补偿技术研究以及大气信道内激光通信物理层与数据链路层参数优化研究，然后研制主光端机和从光端机，并进行外场演示验证试验与性能评价。本项目的实施，将对空间激光通信组网与未来空间信息网络建设具有重要的科学意义和实用价值。

多履带行走装置担负着大型采矿装备的承载和行驶，其行走轨迹的可控性直接影响矿山生产的安全性和开采效率。多履带行走装置通过将转向履带偏转一定角度，利用地面对转向履带的侧向力克服转向阻力的转向方式导致转向轨迹可控性差、履带链和支重轮磨损严重。本项目提出多履带行走装置的非均衡独立驱动模式，联合差速法和偏转法实现协同转向控制，并基于此开展多履带行走装置自适应行走机理及关键技术研究。首先建立多履带行走装置机电耦合动力学模型，优化不同条件下履带驱动和转向系统参数的匹配方案；提出考虑转向稳定性及能耗的多履带行走装置路径规
