The final thesis focuses on the design and creation of an educational robotic arm, as well as the development and fabrication of a cycloidal reducer, suitable for Nema 17 motors. Firstly, we compared existing robotic arms and reducers, and based on this comparison, we proceeded to design prototype components using various materials. We also performed torque calculations for the most stressed axis of the robotic arm. This helped us determine the required power for the cycloidal reducer. For the robotic arm, stiffness tests were essential, evaluating the quality of the arm's component construction. We found that both the shape and the material, along with the manufacturing technology, are important for the robot's stability. In the case of the cycloidal reducer, precise component fabrication and ensuring great tolerances is highly important. Backlash tests and durability tests were crucial for the cycloidal reducer, offering a comprehensive understanding of the wear of the cycloid and its lifespan.
