 iNav, AGVP's intelligent NAVigation system,
is an inertial guidance technology used by Odyssey AGVs to maneuver in manuvaturing facilities of any type. |
iNav utilizes an onboard magnetic sensor to recognize small, powerful
magnets embedded in the floor. These sensors provide the onbard AGV Controller
with position deviations, allowing the vehicle to correct its heading.
iNav is augmented by Odyssey's dead reckoning system. A Drive Motor Encoder measures the vehicle's travel disstance with
65 Pulses per mm of travel and a Steer Motor Encoder measures the seteering angle with an accuracy of 200 pulses per
degree, providing what is possibly the most accurate dead reckoning system available. |
| Magnets are small - [.38" x .5"] - and are embedded in the facility floor. Steel or other elements within the floor do
not affect the magnets. |
 |
Advantages:
- Essentially the same cost as wire guidance
- Simple to install; one magnet every 20 feet of travel
- Ease of maintenance, individual magnets can be checked and replaced as necessary
- Not susceptible to moisture, floor variations or expansion joints
- No single point of failure
Disadvantages;
- Magnets degrade over time [10-15 years]
- Guidance accuracy is less than laser guidance or wire
