PreparationElements such as load-transfer stations, battery-charging stations, servers and the WLAN are positioned in the environment and tied in wherever necessary.

InstallationInstallations are performed and settings are made on individual compo-nents. This could be server software or connection to other systems such as lifts, doors and fire-protection systems.

Training runTo 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.

Information about the physical environmentTo 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.

Ready for operationThe UNITR B/8261 is now available to carry out your tasks.

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

Navigation

Learning waypoints

Waypoints are locations in the physical environment

where actions such as transferring a load are perfor-

med.

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. Depen-

ding on the situation, it stops, makes a detour or

modifies its speed.

Mission planning

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.

Operator interaction

A touch screen on the UNITR B/8261 gives the operator

direct control. You can, for instance, confirm tasks

or display information. Formerly inconceivable prob-

lems can nowadays be solved in an easy way by this

direct interaction between user and AGV.

Navigation

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 applica-

tions 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.

You can find detailed information about our standard

modules in the respective data sheets.

You can’t find a standard module that meets your

needs? 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

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.

Safety – Drive Safe

Chassis / drive

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.

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).

Energy system

An NIMH battery pack, charging electronics and

energy management are combined into one unit to

make up the energy system.

The combination of the proper charging strategy and

the batteries’ power capacity results in optimal

utilisation, availability and efficiency.

Loads and dimensions

A base unit made of aluminium and the use of

high-quality, lightweight materials result in a low

empty weight of 138 kg. The maximum load capacity

is 200 kg.

The overall small exterior dimensions of the UNITR

B/8261 allow excellent mobility even in physical

environments with very limited space.
