The solution concerns the protection of sheep against wolf attacks by modifying the Best-cover mobile shelter. The modification consists in covering the shelter using KARI networks. This ensures that wolves do not reach the sheep. The essence of the technical solution lies in the fact that the KARI nets are attached to the skeleton of the shelter so that the wolves do not climb through, crawl or jump. The functional sample was manufactured by Best-cover, s.r.o. Hořepník.
