How does one control and navigate the AGV?
AGV carts use two types of navigation to determine location. The first is the so-called counting navigation. It’s a very simple solution that doesn’t need specialized equipment for operation. However, its disadvantage is the tendency to accumulate calculation errors. Such errors must therefore be corrected on a regular basis. The second type of navigation is used for this. It may be based on several different operating methods, which are agreed below.
AGV Lean Cart robots don’t need to navigate: magnetic induction, magnetic loop or optical loop. Thanks to this, Lean Cart robots are easy and quick to implement in any environment, and their integration with other machines and devices working in the enterprise does not require any interference with the infrastructure.
Control and navigation in AGV robots
How does one control and navigate the AGV?
AGV carts use two types of navigation to determine location. The first is the so-called counting navigation. It’s a very simple solution that doesn’t need specialized equipment for operation. However, its disadvantage is the tendency to accumulate calculation errors. Such errors must, therefore, be corrected regularly. This is where the second type of navigation comes into play. It may be based on several different operating methods, some of which are discussed below.

Thanks to this, Lean Cart robots are easy and quick to implement in any environment, and their integration with other machines and devices working in the enterprise does not require any interference with the infrastructure.
AGV robots are equipped with a scanner that emits a laser beam. The emitted beam “sweeps” around the cart up to several times a second. By using the triangulation method, it can be positioned. The position of the cart is calculated on an ongoing basis using counting navigation and, if necessary, corrected based on measurements from the laser. Currently, the accuracy of determining the position of the cart can reach even single millimeters.
The use of gyroscopes in navigating AGV cart
In the gyroscopic method, mechanical or optical gyroscopic devices are used to determine the direction of travel. It requires additional calibration devices, so-called transponders, which are mounted at characteristic points of the route, i.e.: at bends, intersections, arches, in places where the AGV carts stop, etc. This method can provide very good positioning, but only if the carts are equipped with high-quality equipment. High quality goes hand in hand with price, which means that high-sensitivity gyroscopic navigation is expensive. Another disadvantage of this solution is also that it’s quite difficult to implement it for routes with complex shapes and a large number of intersections.
The use of these methods of navigation in the Lean Cart AGV robot family has brought us to create our proprietary hybrid navigation that expands the possibilities of working and using Lean Cart robots in industry.
Innovative mobile robots – a revolution in the transport of materials
Lean Cart – an intelligent system of automatically controlled vehicles
We invite you to familiarize yourself with our revolutionary concept regarding the transport of materials. We manufacture so-called AGV forklifts. We have ten years of experience in the design and construction of intralogistics systems. Our robots are characterized by fast implementation and no need for any optical markers due to the intelligent hybrid navigation system. The vehicles are fully autonomous and equipped with safety, navigation, and location systems. All these arguments make them meet the clients’ needs regarding the requirements of Industry 4.0.
The warehouse transport trucks in question are equipped with a very intelligent automatic control system. Thanks to it, transport can be replaced by the use of forklifts and pallet trucks. Thanks to AGV robots, materials can be moved directly – without requiring an operator’s involvement. Despite the innovation, Lean Cart technology is extremely simple – both when it comes to its installation and implementation in any warehouse and production space. It works based on the method of an intelligent combination of modern radio communication technologies in combination with adaptive software to deliver parts and products in the workplace.
Lean-Tech Ltd. offers attractive production solutions – e.g. pallet transport of heavy loads or their delivery. The scope of services also includes assembly of complete production lines. Mobile robots can be used in various conditions in all industries. Their possibilities are practically unlimited due to the universality and versatility of these means of internal transport.
A wide range of offers
Lean Cart’s offer is fully adapted to the needs and expectations of consumers. The most popular are all robots transporting goods, which are placed on hauled carts, as well as on special transport platforms ideally suited for transporting Euro-pallets. The unquestionable advantage of mobile robots is their autonomy. Thanks to extensive IT systems, they can monitor their surroundings. Thanks to having vision systems
they recognize shapes, which translates into the detection and identification of transport platforms as well as automatic charging stations. Mobile robots also have telemetry systems enabling continuous monitoring and diagnostics. More importantly, the software in question is independent of the operating system. Thanks to this, they can be used both on computers and tablets or smartphones.
AGV carts – we focus on innovation
The AGV cart appears as a modern device used to determine the position based on two types of navigation – i.e. counting navigation and laser navigation. The robots are equipped with a modern scanner that emits a laser beam sweeping its surroundings with a frequency of up to several times per second. The location of a given cart is calculated utilizing counting navigation. This allows you to determine the position of the trolley with accuracy up to individual millimeters. The robots are very easy and quick to implement, and their integration with other machines does not involve any interference with the infrastructure. Thanks to innovative hybrid navigation, AGV trolleys can be successfully used in various industries.
Flexibility, efficiency, reliability
If we aim to characterize the mobile AGV robots manufactured by Lean Cart in three words, it will be the following combination: flexibility, efficiency, and reliability. The robots are flexible since the dimension and shape are adapted to the individual needs and expectations of consumers. This is possible thanks to the use of appropriate accessories and components that allow us to shape our devices to any form ordered by customers. Flexibility is one thing. Equally important is the performance of AGV robots equipped with a wide range of drives. It allows you to transport products up to a weight of 1500 kg with a speed of up to 1.2 m / s. Furthermore, the power supply system allows for rapid battery replacement or, depending on the selected technology – instant charging. The minimum operating time of the units is up to 8 hours, and it can be extended up to 7 days. Lean Cart mobile robots are of high quality. All materials that are used to build platforms come from leading manufacturers so that customers have constant access to technical service and the possibility of professional advice in this regard.
