Plug and Use Step 1 Preparation Elements such as load-transfer stations, battery-charging stations, servers and the WLAN are positioned in the environment and tied in wherever necessary. Step 2 Installation Installations are performed and settings are made on individual components. This could be server software or connection to other systems such as lifts, doors and fire-protection systems. Step 3 Training run To learn the upcoming work environment, the UNITR B/8261 is driven through the environment with a joystick. The data gathered at this time is turned into a map of the physical environment, which from then on is needed for navigation later on. Step 4 Information about the physical environment To allow the UNITR B/8261 to interact with the physical environment, the stored map containing information (known as virtual objects) is linked in. In this way, for example, driving areas can be limited and manual transfer stations can be defined. Step 5 Ready for operation The UNITR B/8261 is now available to carry out your tasks.
Navigation Learning the physical environment In order to learn the physical environment in which it will be put to use, the unit requires only a single training run. For this purpose, the UNITR B/8261 is attached to a joystick and driven manually through the physical environment. Definition of driving areas and special objects Various routes are entered and positioned using the graphical user interface. To do so, you have a variety of tools and forms at your disposal. In the same way as defining routes, other aspects such as danger zones, transfer locations, doors, lifts and other similar information can be entered into the physical environment. This step requires no knowledge of programming whereby later adaptations and expansions are very easy to make.
Navigation Learning waypoints Waypoints are locations in the physical environment where actions such as transferring a load are performed. If a high level of precision is required, a waypoint can be self-learned through a teaching process on the UNITR B/8261. If an approximate position is adequate such as for a manual load transfer, the waypoint can be defined using the user interface. Navigation and projected routes Based on this data, the UNITR B/8261 calculates its optimal routes, all of which are traceable and available in various data formats. The navigation system requires no installation of magnets, induction loops, reflectors, etc. The projected route is a fundamentally important function which is needed to reach a destination in a safe manner. The UNITR B/8261 recognises obstacles at an early point in time using safety sensors. Depending on the situation, it stops, makes a detour or modifies its speed.
Navigation Mission planning Operator interaction The tasks to be executed by the UNITR B/8261, called missions, can be created or entered in several ways: automatically generated: connection options through data interfaces to ERP production control systems, etc. manually generated: input by using a web-based user interface from any computer in the network, through tablet PCs or even smartphones. A touch screen on the UNITR B/8261 gives the operator direct control. You can, for instance, confirm tasks or display information. Formerly inconceivable problems can nowadays be solved in an easy way by this direct interaction between user and AGV.
Changing modules Module-changing system The module-changing function makes it possible to execute a variety of tasks with only one AGV. This allows you to increase the utilisation factor, expand an existing system or implement a variety of applications in steps. The change takes place in the module-changing station, where the UNITR B/8261 automatically swaps in the module necessary for the next mission. The software is also modular, and an app for the user interface is installed along with a new module. Then the module is available for use. A most diverse range of uses Whether standard or special uses: MT Robot AG, working together with partners from its sector, offers corresponding solutions with the required background knowledge.

Our experts will work out a suitable concept so that all the advantages of the UNITR B/8261 can be put to work to meet your goals in an optimal way.
Safety Drive Safe Safety The UNITR B/8261 is used widely in both industrial settings as well as in the healthcare sector. This means that it is unavoidable that the vehicle must travel through public areas. With the UNITR B/8261 we have implemented a safety concept that enables its use in these areas. In addition to innovative sensor-based solutions, all construction features were developed and optimised with these challenging application areas in mind. Our safety precautions allow driverless motion in complex physical environments Drive Safe. Anticipated movements Drive Safe not only increase safety but also prevent idle time. You can find more documents about safety on our website.
Vehicle design Chassis / drive Energy system The UNITR B/8261 chassis consists of a differential drive made of two driven wheels in front and a passive trailing roller in the rear. An NIMH battery pack, charging electronics and energy management are combined into one unit to make up the energy system. The advantages and agility provided with this scheme can be seen particularly well in narrow operating areas as well as movement over thresholds (heights up to 20 mm). The combination of the proper charging strategy and the batteries power capacity results in optimal utilisation, availability and efficiency.
