Electric hot-melt nut ironing device

I recreated the author's original model, modified it into an electric version, and added a mechanical lifting structure driven by a steering gear to realize the ascending and descending movement of the manipulator. You only need to prepare a standard steering gear driver or a standard steering gear tester for the whole driving process. Later, you can also modify it into a version controlled by stm32, and you can play it yourself.The required bill of materials is: M3×25 screws,MG995 standard steering gear,Six 608zz bearings.You also need some hot melt adhesive to help you combine the two robotic arms.
