In this way, the light supplement module 10 illuminates and / or supplements light for the visual recognition module 20.

[0036] As shown in Figure 4 and Figure 5 ,Figure 4 A cross-sectional view of the front shell assembly 31 after the light compensation module 10 and the visual recognition module 20 are assembled, Figure 5 A cross-sectional view of the front shell assembly 31 after the light compensation module 10 and the visual recognition module 20 are assembled, Figure 4 A partial enlarged view of part A. In one embodiment, a light compensation module 10 is provided, which includes a mounting bracket 100 and a light compensation lamp 200. The mounting bracket 100 is arranged in a groove-shaped structure formed by two side plates and a bottom plate, and the cross section is generally The mounting bracket 100 is provided with a mounting groove 110, and the inner side wall of the lower side of the mounting groove 110 is provided with a first light reflection part 120. The light compensation lamp 200 is mounted on the bottom wall of the mounting groove 110.

When the robot performs a task in a scene with insufficient ambient light, the light compensation lamp 200 is turned on and emits light, and the first light reflection part 120 on the inner side wall of the lower side of the mounting groove 110 reflects the light shining on it to a farther place, so as to enhance the light in the far place and ensure that the image collected by the visual recognition module 20 does not appear underexposed in the far place, thereby improving the accuracy of visual recognition of the robot in a scene with insufficient external light.

[0038] In this embodiment, the light compensation lamp 200 can be a basic light emitting device such as a lamp strip or a lamp tube. The light compensation lamp 200 can be mounted on the bottom wall 111 of the mounting groove 110 by screwing, clamping, bonding or other fixed connection methods. The first light reflection part 120 is arranged as a light reflection surface, which can be configured as a light reflection sheet or a light reflection coating, and the first light reflection part 120 can be mounted on the inner side wall of one side of the mounting groove 110 by screwing, clamping, bonding, electroplating or other fixed connection methods.

[0044] Please continue to refer to Figure 5 In one embodiment, the light supplement module 10 further comprises a light homogenizing plate 300, which is located inside the installation groove 110 and is spaced apart from the light supplement lamp 200. Thus, the light homogenizing plate 300 can uniformly spread the light emitted by the light supplement lamp 200, so that more light is incident on the first light reflecting part 120, and the first light reflecting part 120 reflects more light to the far distance, ensuring that the light on the side of the target recognition area far away from the light supplement module 10 is sufficient, so that the uniformity of the light at the target recognition area is increased, thereby further improving the recognition accuracy of the robot in a dark environment.

[0045] Specific to the embodiment, the light uniformity plate 300 is set as a light scattering powder light uniformity plate, and the light scattering powder light uniformity plate is milky white. In this way, the light uniformity plate 300 can avoid the light compensation lamp 200 from being directly exposed in the user's visual angle, and improve the texture of the robot. In other embodiments, the light uniformity plate 300 can also be set as a light transmission light uniformity plate with stripes.

[0048] As shown in Figure 5 in an embodiment, the light compensation module 10 further comprises a light transmission lampshade 400, and the light transmission lampshade 400 is arranged on the slot of the mounting groove 110. In this way, the light transmission lampshade 400 plays a protective role at the same time, and the light in the slot can also pass through the light transmission lampshade 400 and irradiate to the target recognition area.

[0049] Further, the light transmission lampshade 400 comprises a light transmission part 410, and the light transmission part 410 is arranged in a spaced manner with the light uniformity plate 300. Preferably, the light transmission part 410, the light uniformity plate 300 and the light compensation lamp 200 are arranged in parallel.

[0050] As shown in ​ optionally, the light transmission lampshade 400 further comprises a mounting wing 420, and the mounting wing 420 is arranged on both sides of the light transmission part 410 and extends outward; the mounting bracket 100 further comprises a connecting part 160, and the connecting part 160 is arranged corresponding to the mounting wing 420, and the connecting part 160 is configured to be fixedly connected with the mounting wing 420 when the light transmission lampshade 400 is arranged on the mounting groove 110.
