Webb offers the widest selection of guidance options for its Automatic Guided Vehicles (AGVs). This allows us to provide our customers with the best possible solution at the lowest price. Our guidance options include:
- Inertial – Webb’s proven inertial guidance system is similar to the technology found in military guided missiles. Vehicles use a solid state gyro VCC3 (Vehicle Control Computer) to accurately maintain the intended path and speed and to perform required tasks. Transponders or SmartMarks® embedded in the floor are sensed by the vehicle to confirm the specific location of the vehicle. Inertial can operate in nearly any environment including tight aisles or extreme temperatures and has a longer lifespan than other guidance options.
- Laser – Vehicles navigate by using a laser scanner that measures angles and distances to reflectors that are mounted to walls and machines. Laser provides maximum flexibility for easy guidepath changes – no system shutdown necessary.
- Wire – Vehicles follow a low voltage, low frequency signal sent over in-floor wires. To change paths, the vehicles switch to a different frequency. This simple guidance system is widely used because of its accuracy and dependability.
- Magnetic tape – Vehicles follow magnetic tape that is installed on top of the floor – no cutting or drilling into the floor. This method is the most cost-effective and flexible allowing guidepath changes to be made in hours. Also, Webb provides a simple configuration tool called CartTools® for its magnetic tape-guided vehicles that allows customers to set up the functions to be performed by the vehicle at specific locations along the guidepath. CartTools is a Windows-based PC software package.
