For a robot to accomplish a given high-level task – such as grabbing an object on a conveyor belt and placing it on a shelf – this task must be translated into low-level commands understandable by the robot operating system. This whole process, known as "motion planning," can be broken down into a number of steps, as illustrated in Fig. …

Factors to consider when selecting idler spacing are belt weight, material weight, idler load rating, belt sag, idler life, belt rating, belt tension, and radius in vertical curves
Well designed conveyors are very robust and reliable machines. These inherent features of belt conveyors can lead to complacency where standard procedures are ignored and attitudes about the dangers of conveyors become lackadaisical. Conveyors can be abused by overloading, improper operation, or lack of maintenance and still perform.

Belt Widths The belt widths are as follows: 18, 24, 30, 36, 42, 48, 54, 60, 72, 84, and 96 inches. The width of the narrower belts may be governed by the size of lumps to be handled. Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt.
