Roboticwork Is Leading the Revolution in Construction Technology
Roboticwork belives that design, archicecture and construction can be more efficient threw 3D concrete printing. 3D concrete printer can reduce construction times by up to 50%, depending on the project. Additionally, this method can lower costs and energy use, making it an attractive option for sustainable construction. Our 3D concrete printing robotic arm M.A.R.S. sets new standards within the industry.

Technology
MARS redefines the 3D concrete printing robotic arms
Mars is a self-moving autonomous reproduction system. It is a 3D printing device of the SCARA robot type. It is capable of printing objects within a perimeter of 8 meters from its own center.
Mars uses its own belt chassis for movement, which, after reaching the point from which it is ready to print, is reconfigured into a position on three legs. These are spaced at 120-degree angles from the center of the device. The chassis consists of three belts. Each of them is rotatable in two axes. The belts are rotatable on a common base. A connectable column is attached to this base, along which the print head moves along a vertical axis. The printing mass consists of a dry concrete mixture, which is supplied in bags, in big bags, or in silos.
To control the device after starting the central power supply system, a graphical interface is used, portable from a computer using its own wifi network. The graphical interface is shareable with optional touch screens. It is made up of an intuitive base layer, which is used to operate all moving parts of the device. The system works with BIM (Building Information Modeling) Which is, in principle, a database of information about a building, which can be represented as a 3D model enriched with information, i.e. its individual building elements BIM objects contain geometric and non-geometric information.

Projects
MARS saves time and costs as proven in real world
MARS 3D concrete printing arm was used by the construction of water tower that was part of shopping complex based in Slovak Republic in Voderady. The construction process was fully onsite. Thanks to this it increases the efficiency and decreases the waste.
Technical information
CHASSIS
The 3D printer uses its own track chassis for movement, which, when it reaches the point from which it is ready to print, reconfigures into a position on three legs. These are positioned at 120-degree angles from the center of the device.
UNLIMITED PRINT HIGH
The 3D printing device uses a central column with the possibility of connecting meter segments. The height of the column is not limited and is fixed to the structure using metal rods attached to the column and the printed parts of the structure. Each meter segment of the column has three threads in the middle oriented in three directions, which allow the connection of anchor rods. After leveling the column, balancing is active up to approximately 1,500 mm of printing height.
ARM LEVELING
3D printing devices use active motor control for arm leveling, which means that the electronics keep the arms in a horizontal position even when exposed to external forces (e.g. wind, inertia). The two beams on which arm no. 1 is mounted are designed so that two motors using rods can change the angle of the arm in two axes by combining thrust. A gyroscopic sensor located in arm no. 1 provides the computer with data on the change in position. Based on this, the computer adjusts the correct position of arm no. 1 using one or the other motor, which also affects the leveling of arm no. 2.
LIFTING ARMS
After the print is finished, a non-printable circle with a diameter of 1.2m can remain in the center, through which the device can move down the
column. This allows the vertical raising of the arms, which is integrated into the design of the device. Thanks to the combination of leveling and lifting, the traction motors located in the central head in the upper part are sufficient for operation.
PRINT RANGE
The device is designed to print objects in a circular range with a diameter of 16m, with the ability to print at least to the inner circle with a diameter of 0.8m. The design of the Scara type print arm allows the print nozzle to approach the circumference of the central head of the device, which allows printing house partitions in the vicinity of the center of the printer.
TRANS AXLE
The transmission of the driving moment of the arm No. 2, which rotates around the end point of the arm No. 1, is ensured by a cardan, flexibly mounted in special bearings so that it is not affected by the tilting of the arm No. 1 due to self-leveling. Similar to racing cars, the gearbox is disconnected from the engine, which strains the system. The transmission of force between them is ensured by an aluminum hollow shaft. After the arm is raised, the cardan is disconnected.
SELF-LOCKING GEARBOXES
The precise movement of the arms is ensured by self-locking worms and gears. Their location and shape of the teeth are designed to eliminate play in the drive using pressure springs and mounting in special bearing housings. The gear transfers movement to arm No. 2 and is driven by a worm. The shape of the teeth is designed to touch the side walls without play. The system is secured against horizontal displacement by means of tension rods and an external carbon cover.
