A modular system is what gives the RTE Robot its broad variability. It consists of three perfectly coordinated components: the fully electrically powered basic vehicle, a kit of interchangeable add-on modules, and a robust radio remote control. The tracked vehicle has a standardized platform (quick coupling system) that accepts any type of live load, with the base area being the same dimensions as a Euro-pallet (1200 x 800 mm). The remote control device is not only used to issue travel commands, but also to control all optional equipment that can be incorporated or transported. The operating philosophy is the same as for radio remote controls in Rosenbauer vehicles.

The robot's live load is up to 650 kg, with a dead load of around 350 kg. The quick coupling system makes changing between add-on modules much faster. The changeover of particularly heavy superstructures can take place via an electronically operated live load changing system, which places it on a jacking system.

The robot is controlled with one hand (single-handed operation) using a joystick, while the add-on turret is controlled with the other hand using a joystick and function keys or toggle levers (on/off, flow and jet adjustment, etc.). The remote control can also be equipped with a 3.5“ display, which can show the images from cameras. A special feature on the control unit is the function key for the "Water discharge!" command, which is not given by the vehicle machinist, but by the operator of the robot. This command opens a flap specially installed on the turret. The control range is around 200 m, depending on the environment.

The RM15 turret live load module makes the RTE Robot an efficient firefighting unit. The Rosenbauer RM15 turret enables quantities of up to 2,000 l/min at throw ranges of 65 m. The turret is protected against the effects of heat by a stainless steel covering hood; in addition, a self-protection nozzle wets the entire superstructure module with extinguishing agent.

The RM35 turret live load module turns the RTE Robot into a high-performance firefighting unit. The Rosenbauer RM 35C turret enables volumes of up to 3,800 l/min at throw ranges of 80 m. The turret is protected against the effects of heat by a covering hood made of aluminum; in addition, a self-protection nozzle wets the entire superstructure module with extinguishing agent. An additional pressure outlet enables emergency crews to carry out post-extinguishing work directly from the robot using a nozzle.

With the roll-on/roll-off container transport live load module, the RTE Robot makes roll containers mobile and thereby ensures a considerable increase in flexibility in deployment. The multi-part platform is attached to the standard anchors on the robot without tools. A pair of access ramps is used to drive the roll-on/roll-off containers onto the live load module. The live load module is suitable for a wide variety of wheel configurations on the roll-on/roll-off container, such as two swivel and two fixed castors as well as four swivel castors.

The greater width of the RTE Robot, 1,070 mm, makes it possible to transport roll-on/roll-off containers in a unique way. Rails are attached directly to the chassis between the crawler tracks and the central body of the robot, on which the roll-on/roll-off container can stand. The larger track width and the lower position of the roll-on/roll-off container ensure a better center of gravity and, especially for driving on rough terrain, even greater stability. A pair of access ramps is used to drive the roll-on/roll-off containers onto the live load module. The live load module is suitable for a wide variety of wheel configurations on the roll-on/roll-off container, such as two swivel and two fixed castors as well as four swivel castors. However, the rollers must all have the same track width!
