Sure thing, let’s get to the heart of it. Start with a sturdy frame—steel tubing or a welded 2x4 skeleton, maybe 4‑5 inches thick so it can take a hit. Cover it with a layer of high‑density foam, then wrap a thick layer of shredded rubber or rubberized foam for the outer skin. That gives you both toughness and a little give when you strike. Now for movement, run a few heavy‑duty servo motors or a small DC gear motor along the shoulders and hips. Tie them to a simple link‑and‑pivot system so the dummy can shift weight and even lean in a chosen direction. If you want more realism, attach a small hydraulic or pneumatic cylinder to the chest that can push back against a grab—just a basic air pump and a quick‑release valve will do. Make the core of the dummy a weighted block of cast iron or lead bricks—enough to stay in place but not so heavy you can’t manipulate it. Add a few removable “target” pads on the shoulders and hips that you can bump up or lower to change the resistance level. Finally, wire everything to a small microcontroller. Program a simple PID loop to keep the dummy balanced when it’s being pressed. You’ll have a moving, resilient partner that won’t quit when you’re doing the clinch drills. Ready to start building?
