Development and evaluation of a laser plane slope generator system for application in land leveling and construction process

Laser measuring and control systems are one of the most important practical technologies and have a wide usage in medical, civil, manufacturing and agricultural fields. A wide variety of industrial products are developed for computerized control of earth moving processes. Machines like grader, loader, scraper, and tractor are able to be equipped with these devices and operate precisely and effectively. The operation is based on producing a reference laser plane in 3 or 4 meters above the ground and then the machine makes a plane with the similar pattern on the ground. Laser plane sometimes has to be completely horizontal and sometimes sloped in one way or sloped in a dual or complex way. Conventional transmitters and generators of laser plane are automatic and have a high price, about 5000$. This research proposes a mechanical-electrical method to replace with the automatic one, and has evaluated its efficiency. As a result, although the precision of this method is lower than automatic one, its price is 1/5 of the automatic method. The possibility of expanding the market of civil and agricultural laser devices increases with this system due to its low price.
