Joakim Moll developed foundational servo motor rotation control for a robotic arm in the ctaqvist/Knowit-NFK-25 repository, focusing on embedded systems and hardware control using Python. He implemented servo object initialization and designed a real-time loop to cycle the arm through minimum, mid, and maximum positions with managed delays, enabling reliable hardware-in-the-loop testing. This work established a testable base for automated arm movement, supporting future hardware integration and feature expansion. The approach demonstrated disciplined version control and effective delay management, providing depth in embedded robotics engineering while addressing the need for robust, repeatable movement control without reported bugs during the period.
