Self guided vehicles is an autonomous navigation and positioning technology that does not radiate energy to the outside and does not rely on external information. The advantage is that after determining the initial conditions, the current position, direction, and speed can be determined without relying on external references. This kind of precise geography environment and precise location under the influence of the outside world can then continuously measure the position change and maintain the dynamic attitude reference accurately. With the advancement of science and technology, the “self guided vehicles” positioning technology with lower cost and smaller size has been gradually promoted to industrial and military fields, and has been more maturely applied in public security fire fighting and emergency rescue.
self guided vehicles AGV is suitable for the following scenarios:
1. The space is relatively narrow, requiring AGV to move forward, backward or sideways;
2. Large scenes with long distances and complicated path laying require multiple AGVs to cooperate to complete tasks;
3. No fixed route is needed, AGV can move with full freedom;
4. Occasions of frequent route changes and site expansion;
5. Other applications where it is not convenient to lay magnetic stripe and other equipment.
Taking the self guided vehicles AGV positioning product independently developed by IKV as an example, the positioning accuracy reaches 0.3%, which is equivalent to walking 1 km with an error of less than 3 meters, which can provide high-precision heading, pitch, and roll for AGVs and forklifts. After obtaining the driving wheel data and the inertial guidance acceleration information, it can output robust inertial navigation positioning results. According to the AGV driving speed of 3m / s, the positioning error within 10s is better than 5cm (excluding the effects of environmental interference, AGV jitter, and slippage).
In the actual application scenario of AGV, the area of storage, factory, etc. is often relatively large. In the case of large scenes and long distances, due to the inherent drift rate of inertial navigation, there will still be a large cumulative error, which requires external information for calibration. IKV robots will try their best to overcome difficulties, reduce errors to a minimum, and bring customers more self guided vehicles AGV.
