Description

Technical Field

[0001] The utility model relates to the technical field of mobile robots, in particular to a mobile robot for sensing directions. Background Technique

[0002] As an intelligent machine that can work semi-autonomously or fully autonomously, robots have been widely used in many fields. Among them, when a mobile robot with a target tracking function is in use, it mainly collects surrounding images through its own image acquisition end, and transmits the collected images to a processing terminal for analysis, and then drives the robot to move to track the target according to the analysis results.

[0003] At present, the existing image acquisition end is usually directly exposed to the external environment, which makes it vulnerable to external factors. For example, it may be impacted. In addition, when an object blocks the image acquisition end, such as a plastic bag or other lighter objects being blown onto the image acquisition end, since it is difficult to deal with these blocking objects, it will affect the effect of the image acquisition end collecting images, and thus have an adverse impact on the target tracking of the robot. In view of this, we propose a mobile robot for sensing directions. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a mobile robot for sensing directions, which can solve the problems raised in the above background technique.

[0005] To achieve the above object, the mobile robot for sensing directions proposed by the utility model includes a seat, a placement seat is fixedly connected to the top of the seat, a support plate is fixedly connected to the inner wall of the placement seat, a lifting structure is arranged on the support plate, and a cleaning structure is arranged on the lifting structure.

The output end of the third motor is fixedly connected to a second gear. An installation groove is formed in the fixed seat. The third motor is fixedly connected to the inner wall of the installation groove. A cover plate is threaded on the inner wall of the installation groove.

[0012] Preferably, a rotating ring is rotatably connected to the inner wall of the fixed seat. An external gear ring is fixedly connected to the outer wall of the rotating ring.

[0014] The utility model provides a mobile robot for sensing direction, which has the following beneficial effects:

[0015] (1) When the image acquisition device of the mobile robot for sensing direction is blocked, starting the second motor can drive the rotating plate and the image acquisition device to rotate to observe the surroundings. At the same time, starting the third motor drives the second gear to rotate. Through the meshing with the external gear ring, the rotating ring rotates, and then drives the cleaning rod to wipe the surface of the transparent cover, so that the residues on the surface of the transparent cover are removed, solving the problem that the blocking object affects the image acquisition effect of the image acquisition device, ensuring that the device can perform stable tracking work in various environments, and improving the reliability and stability of the robot target tracking.
