construction, road and lifting equipment.
It is important to understand that industrial robots within one robotic complex can be
used both for the manufacture of products of the same type with minor differences in size, and
for the manufacture of products that differ in design. At the same time, there are trends to
expand the scope of application of robotics in the construction industry, primarily through the
development of complex robotic technologies.
Figure 5 shows the process of preparation for welding of a truss tubular structure of a
construction tower crane. The quality of welding of such structures is largely determined by
the correct groove of the edges of the abutting parts. It is important that the permissible error
in the positioning of the welding head corresponds to the tolerances for the dimensions of the
parts being welded [3]. The production of parts to be welded with specified tolerances can be
provided by a robotic complex of blank production.
The use, along with a robotic welding complex, of a robotic complex with laser cutting of
edges is an example of an integrated approach to the creation of new robotic technologies.
