Abstract

The invention discloses a planet vehicle stabilizing platform. A supporting frame is arranged on a planet vehicle; a first adapter piece is rotatably connected to the supporting frame through a firstrotating shaft; a second adapter piece is rotatably connected to the first adapter piece through a second rotating shaft, and the first rotating shaft is perpendicular to the second rotating shaft; amovable platform is rotatably connected to the second adapter piece through a third rotating shaft, and the third rotating shaft is perpendicular to the second rotating shaft; a first driving device drives the movable platform to rotate around the first rotating shaft; the second driving device drives the movable platform to rotate around the second rotating shaft; the third driving device drivesthe movable platform to rotate around the third rotating shaft; and a stable object is arranged on the movable platform, and when the planet vehicle is unstable, the movable platform is driven to rotate around one or more of the first rotating shaft, the second rotating shaft and the third rotating shaft to restore to an initial position so that the stable object is kept stable. According to the stabilizing platform, the three driving devices are connected in parallel to drive the movable platform to rotate around the three shafts to counteract shaking, the stable object is kept stable, control precision is high, and a structure is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of stabilizing devices, in particular to a stabilizing platform for planetary vehicles. Background technique [0002] When human beings detect extraterrestrial celestial bodies, they usually use planetary rovers for inspection and detection, such as the surface patrols of extraterrestrial celestial bodies such as the moon, Mars, and asteroids. Planetary vehicles often have shooting equipment such as navigation cameras and panoramic cameras. Due to the poor road conditions on the surface of the planet, the planetary car will bump violently during fast driving, and it needs to take pictures of the road conditions in front of the road. The planetary car will analyze the photos taken for route planning and realize autonomous continuous driving. Therefore, the star rover is equipped with a stabilization device to stabilize the camera and prevent it from shaking. [0003] Existing stabilizing devices usually use...
