For example, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present specification. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
The radar module, the robot, and the autopilot module according to the present specification will be described in detail below with reference to the accompanying drawings. The features of the following examples and embodiments may be combined with each other without conflict.
Referring to fig. 1-2, a robot according to the present disclosure includes a radar assembly that can be used to detect the position of an object to prevent the robot from colliding with the object during travel. The radar assembly comprises a radar 1 and a reflecting device 2 located at one side of the radar 1. The robot can also be an autopilot assembly, such as an autopilot takeaway cart or a restaurant autopilot serving cart.
The reflecting device 2 can be prevented from being fixed to the radar 1 by, for example, a snap, etc., the radar 1 being assembled to a support (not shown) of the robot; or the radar 1 and the reflecting device 2 are assembled on a bracket of the robot respectively.
The reflection device 2 includes a main body 20 having a recess 201, and a first reflection portion 202 and a second reflection portion 203 located in the recess 201. The first reflective portion 202 is perpendicular to the second reflective portion 203, and the second reflective portion 203 is located above the first reflective portion 202.
The radar 1 is partially located in the recess 201. In the illustrated embodiment, the radar 1 can emit electromagnetic waves to the 360-degree range of the peripheral plane of the radar 1, that is, the maximum included angle between two beams of electromagnetic waves emitted by the radar 1 is 360 degrees. Wherein, the electromagnetic wave within the range of more than 0 degree and less than 180 degrees can be shielded and reflected by the reflection device 2 and then emitted. That is, an angle between one of the electromagnetic waves and the other electromagnetic wave that can be irradiated to the first reflection portion 202 is greater than 0 degree and smaller than 180 degrees. For example, the first beam of electromagnetic waves 10 is irradiated onto the first reflection part 202, reflected by the first reflection part 202, irradiated onto the second reflection part 203, and reflected by the second reflection part 203 to form a second beam of electromagnetic waves 11 parallel to the first beam of electromagnetic waves 10 and then emitted. After irradiating to the object, after reflection, irradiating to the second reflection part 203, after reflection of the second reflection part 203, irradiating to the first reflection part 202, after transmission of the first reflection part 202, entering the radar 1, so as to detect the position of the object. The second beam of electromagnetic waves 11 is located above the first beam of electromagnetic waves 10. The first beam of electromagnetic waves 10 is in the opposite direction to the second beam of electromagnetic waves 11. The electromagnetic wave within the range of more than or equal to 180 degrees and less than or equal to 360 degrees is not shielded by the reflecting device 2, is directly emitted, irradiates an object, and is reflected to the radar 1 so as to detect the position of the object.
The distance measured by the electromagnetic wave within the range of 180 to 360 degrees is the actual distance from the radar 1 to the object. If the distance from the first beam of electromagnetic waves 10 to the first reflection part 202 is d1, the reflection distance from the first reflection part 202 to the second reflection part 203 of the first beam of electromagnetic waves 10 is d 2. And subtracting 2 x d1 from the measured distance of the second beam of electromagnetic waves 11 and then subtracting d2 to obtain the actual distance from the radar 1 to the object.
In the illustrated embodiment, the electromagnetic wave within the range of 0 degree to 180 degrees is shielded and reflected by the reflection device 2 and then emitted, but the present application is not limited thereto. The range of the radar 1 sheltered from the reflecting device 2 can be changed according to actual needs, and the range is not limited in the application.
In the radar module according to the embodiment of the present invention, the reflection device 2 is provided to reflect the electromagnetic wave emitted from the radar 1 and emit the reflected electromagnetic wave, thereby increasing the detection range of the radar 1.
