This is the paint robot project we designed with my teammates Berkem Can Özcan and Oktay Bozacı in the 1st final project of Mechatronics Engineering. It has been developed for painting the spinner part in robot aircraft engines. The operation is carried out by an operator in its current state. This causes both high costs and security risks. Different robot designs have been developed to automate this process. Cost analyzes of these designs were made.
