The large multi-functional autonomous robot designed by Weir, although derived from Perfikot's large engineering autonomous robot, if the two were placed together, one could immediately notice the difference.
To draw an analogy, one looks like a pragmatic craftsman with many tools, while the other resembles a shrewd and capable courier.
Although named multifunctional, the essence of the autonomous robot designed by Weir is to transport goods.
The reason it is called a multifunctional autonomous robot is mainly because it can autonomously clear, maintain, and repair roads and railways, while also possessing certain combat functions, able to be linked or fitted with specialized containers, etc...
Though most functions are transportation-oriented, that does not prevent it from being dubbed as multifunctional.
After these robots were made by Weir, they quickly began transporting supplies to settlements around Chernobyl, centered on Chernobyl itself, following pre-programmed maps.
