Research on laser beam riding guided excavator

Many projects are in dire need of horizontal and depth controlled. We devised a control system that will equip excavator to make it digging at a controllable depth base on the laser beam riding guiding and obliquity sensing technology. Our system captures the signal of angle and depth of the bucket grab, makes geometry operation, then gives the depth result of the shovel point. We applied the system to a excavator and made experimentations. The result indicated that the system can ensure a 2 centimeter precision.
