The present technology is generally directed to a conveyor system and a method of using thereof. In various embodiments, the conveyor system includes: a conveyor belt; a frame; a plurality of rollers supported by the frame and configured to support the conveyor belt, wherein each of the plurality of rollers has two end portions and a middle portion between the two end portions along a length direction of the roller, the roller is supported by the frame at the two end portions, and the middle portion has a smaller diameter than the two end portions; a drive system configured to move the conveyor belt; and a control system configured to control the drive system.

A device for transporting objects, including a first conveyor element and a second conveyor element. The first conveyor element protrudes beyond the second conveyor element, a first conveying surface being formed by the first conveyor element, and a second conveying surface being formed by the second conveyor element. The first conveying element being movable in dependence on the weight of the object to be transported, so that a first object of a first weight is moved on the first conveying surface and a second object of a second weight is moved on the second conveying surface, the second weight being greater than the first weight.
