One of the biggest problems of construction machines that make people's lives easier is digging efficiency. In this study, a new excavator teeth model with a biomimetic approach was developed to solve the problem of digging efficiency. This biomimetic digging teeth model is inspired by the front claw of the armadillo, which is naturally a successful digging animal. In the bucket, only the teeth are biomimetic and in the armadillo teeth model, the 5 mm deep thinned parts on the sides of the standard bucket are determined as 25 mm deep in the armadillo teeth model for extra lightness. In addition, a standard digging tooth was designed and finite element analysis of this standard design and the armadillo design was carried out using different steels. The designs were created using the CATIA V5 R21 program. The analyzes were carried out using the Ansys Workbench 18.1 program. Three different steel groups were used for the analysis results. These were St-37, S690QL, and Weldox900 E steels. Total deformation, safety factor, equivalent stress, and cost analysis were carried out. The average stress values were 228.85 MPa for the standard teeth and 162.01 MPa for the armadillo teeth.
