Amphibious spherical excavating and sampling robot capable of moving in all directions

The invention discloses an amphibious spherical excavating and sampling robot capable of moving in all directions, according to the spherical robot, through the design of an inner spherical shell and an outer spherical shell, wheel thorns which are used for excavating and easy to wear are installed on the outer spherical shell, and the totally-closed spherical shell structure characteristic of the spherical robot is reserved, so that the robot can freely move in water; meanwhile, the pod rod design is applied to the spherical robot, so that when the robot achieves external operation, the integrity of the spherical structure is kept to the maximum extent, and the robot has good passing ability and extremely high environment adaptability and has great potential advantages and research value. 本发明公开一种可全向移动两栖球形挖掘采样机器人，该球形机器人通过内外球壳的设计，将用于挖掘的易磨损轮刺安装于外球壳，保留了球形机器人全封闭的球壳结构特点，使本发明所述机器人可在水中自由活动，同时将豆荚杆设计应用于球形机器人，使本发明机器人在实现对外操作时，最大程度的保持了球体结构完整性，使机器人具备良好的通过性和极强的环境适应能力，具有很大的潜在优势和研究价值。
