Disclosed is an in-situ detection robot for loess geological information, including a housing, an active tensioning system, an auxiliary tensioning system, a control system, a drive system, and a detection system. The active tensioning system is configured to provide the robot with a tensioning force in an aperture direction of a loess hole for the robot to travel in the loess hole. The auxiliary tensioning system is configured to provide the robot with a pre-tensioning force for the robot to travel in the loess hole. The control system is configured to control a movement mode of the robot according to different travelling environments of the robot in the loess hole. The driving system is configured to provide the robot with a travelling power in the loess hole. The detection system is configured to detect related parameters of the loess geological information. The robot according to the present disclosure has a simple structure, can adapt to an aperture change of 100-150 mm, can effectively solve the problem in which the crawler pipe robot has a large radial size, has strong obstacle crossing ability and trafficability performance, and is applicable to the detection of geological information in the loess hole, which fills the existing technical gap.
