NASA Challenge: passive support system in motion, active Restraint for back and leg support for working in fixed positions

grabcad

I propose a very light, economical and effective siencillo exoskeleton (carbon fiber) that is passive when performing movements with the force of the muscles (as can be seen in the demonstrative video) and that is active in maintaining a fixed working position by slowing down the movement of the joints with electromagnets that function as electronic disc brakes , so the position of a person's back and legs is supported by simply pressing the energizing button on the coils of the electromagnets of the exoskeleton joints, and can be temporarily kept to the ground or fences by electromagnets that it possesses in the boots or claws acted by serbomotors
