Navigation Technology

There are several forms of Navigation/Guidance Technology available today. Selecting the correct technology for your application is sometimes the difference between a successful and an unsuccessful system. The end user must acquire a reasonable knowledge of the guidance technology before making an informed decision about which navigation type to use.

The most popular forms of Automatic Guided Vehicle (AGV) navigation are laser, spot, magnetic tape, natural, and wire. Keep in mind that selecting the navigation/guidance technology involves reviewing the current project, as well as any future expansions/changes. The Transbotics’ Application Sales Team can walk you through the process and provide experienced direction and commentary.

Here are some examples of various navigation technology's key benefits:

 

Laser Guidance Technology

Laser Guidance
  • Area is mapped and stored in the vehicle’s computer memory
  • Multiple, fixed reference points, reflective strips, located within the operating area that can be detected by a laser head that is mounted on the vehicle
  • Guide path is easily changed and expanded
  • Most flexible for vehicle movement
  • Most reliable and secure form of navigation
  • Most accurate form of guidance
  • System can be expanded without alteration to the facility
  • Most dynamic control of blocking and traffic management
  • Recommended by TRANSBOTICS

 

Magnetic Spot Guidance Technology

Magnetic Spot Guidance, Inertial Guidance
  • Guide path is marked with magnetic pucks that are placed on or in the floor
  • Guide path sensor is mounted on the vehicle
  • Paths are open, the systems guide path can be changed
  • Extensive layouts can complicate the layout of magnetic pucks
  • Depending on the accuracy of the magnetic sensor, calibration of the position may be required for  different vehicles
  • System can be expanded without damage or major alteration to the facility

Magnetic Tape Guidance Technology

Tape Guidance
  • Guide path is marked with a magnetic tape that is placed on the floor surface
  • Guide path sensor is mounted on the vehicle
  • Paths are continuous
  • Paths are fixed, the systems guide path can be changed easily and quickly
  • Tape may have to be epoxy coated to floor
  • Recommended for Automatic Guided Carts (AGC)

Inductive Guidance Technology (Wire Guidance)

Wire Guidance
  • Floor is cut and a wire is imbedded to represent the guide path
  • Guide path sensor is mounted on the vehicle
  • Paths are well marked on the floor
  • Paths are continuous
  • Paths are fixed, the systems guide path is not easily changed
  • Expansion of the facility is not as flexible as some other navigation technologies and may be limited due to constraints

Natural Navigation

Automatic Guided Vehicle natural navigation
  • Area is mapped and stored in the vehicle's computer memory
  • Use of existing environment scanned by laser bumpers, with the aid of a few fixed reference points
  • Guide path is easily changed and expanded
  • Most flexible for vehicle movement
  • System can be expanded without alteration to the facility
  • Dynamic control of blocking and traffic management
  • Ideal for environments that can change frequently, but not significantly
  • Short installation times, reducing costs and minimizing the effect on operations
