a second camera assembly coupled to a rear bumper of the vehicle body.

7. The autonomous vehicle of claim 6 , wherein the plurality of camera assemblies further comprise:

a third camera assembly coupled to a first door frame of the autonomous vehicle; and

a fourth camera assembly coupled to a second door frame of the autonomous vehicle, the second door frame spaced apart from the first door frame along a lateral direction of the vehicle body.

8. The autonomous vehicle of claim 5 , further comprising:

a first cleaning system configured to clean debris from a housing of the Lidar unit; and

a second cleaning system configured to clean debris from a lens of the camera.

9. The autonomous vehicle of claim 5 , wherein the camera mount defines an opening configured to accommodate a lens of the camera.

10. The autonomous vehicle of claim 5 , wherein the at least one camera assembly further comprises:

a retention plate configured to retain the camera within the cavity defined by the camera mount; and

a spring plate positioned between the camera mount and the retention plate.

11. The autonomous vehicle of claim 5 , wherein:

the Lidar unit contacts the first surface of the Lidar mount; and

the camera mount contacts the second surface of the Lidar mount.

12. The autonomous vehicle of claim 5 , wherein the camera is tilted at an acute angle relative to the Lidar mount.

13. The autonomous vehicle of claim 5 , wherein the camera has a 360 degree field of view.

14. An autonomous vehicle control system comprising:

a sensor platform comprising a Lidar mount and a camera mount, the Lidar mount couplable to an autonomous vehicle, the Lidar mount comprising a first surface and a second surface that is different than the first surface, the Lidar mount defining a first aperture and a second aperture, the first aperture and the second aperture respectively extending through the first surface of the Lidar mount and the second surface of the Lidar mount, the camera mount coupled to the second surface of the Lidar mount with a first fastener configured to extend through the first aperture defined by the Lidar mount, the camera mount defining a cavity;
