In this video, I test a QDD robotic actuator that I fabricated using a 3D printer, paired with my custom-built ESC. The actuator incorporates a cycloidal reducer for high speed and torque, and I employ SVPWM for precise control. From design insights and assembly steps to a detailed performance test, I showcase the potential of this actuator and discuss future improvements.
