What a brilliant contraption !
Was that your own design ?
It's like the six million dollar mannequin, a bionic robot you can punch the snot out of.
I feel like going to Target and beating up one of their display mannequins now.
It was actually my wife's idea, though she was joking at the time. I was working a lot of OT and swing shift, and even though I'd accumulated a decent amount of formal training I could never spar. "You should make a dummy that hangs off of a pole in front of you, like a big cat toy."
"Hmmm. It would have to be on casters..." and off to the races. It uses a bunch of anchor points and pulleys on the back, and three lines control the arm movements, one that mimics the bicep, one the triceps and one the lats that also limits overtravel. In addition to the demo'd strikes it can also do an overhand stab/hammer fist. I gave it grabby hands in a later upgrade, so I could work with wooden knife and padded stick.
It is "The Bully" courtesy of Gut Check Productions. The body pads are very dense and it has a lumber and large size PVC frame, so padding on the hands/shins etc is mandatory. Will tolerate full power Muay Thai shin kicks to the leg or body, sweeps, any hand strike, rattan sticks, whatever. You can also use it for preliminary takedown entry, heel-picks, upright arm drags.
Has two modes - a partner can work the handles or you can wear the belt. Rotating the upper body relative to the lower is what pulls ropes/creates the energy for the strikes.
Training with a buddy working the controls is like fighting the Terminator - as hard as you can hit only slows it down, the advance is relentless and makes you really get in the habit of moving laterally, evading, hit hard and away, strike the arms when possible - all the stuff that will improve your odds in a real brawl. Plus, they can't see 100%, so you really need to mind your D or you'll get a fat lip, bloody nose, lump on the forehead - the thing is a riot when its working!
Possibly the coolest thing about it, you can work on stuff that is just plain too dangerous to actually apply on a partner. Full power head butts, punching the back of the opponent's hands, full power stop-hits to the opponent's biceps.
Alas, the stress on the shoulders is enormous and I have yet to figure out a durable solution, only runs for about 30-40 hours before it needs a rebuild. It sits in my garage with one arm draped over its other shoulder, waiting to come to life again.
Still no sub for hands on person to person, but anything that reinforces good habits is a big plus.
