Editing Exoskeletons and the Architecture of the Augmented Human (section)

* '''Powered Exoskeleton''' — A wearable mobile machine that is powered by a system of electric motors, pneumatics, levers, hydraulics, or a combination of technologies that allow for limb movement with increased strength and endurance.
* '''Passive vs. Active Exoskeletons''' — *Active*: Uses heavy batteries and motors (actuators) to physically push and lift the human's limbs. *Passive*: Has no motors or batteries. Uses springs, dampeners, and counterweights to mechanically store and release the human's own kinetic energy, reducing fatigue without requiring a power source.
* '''Rehabilitation Exoskeletons''' — Medical devices used in physical therapy clinics. A patient who has suffered a stroke or spinal cord injury is strapped into the machine. The machine physically forces their paralyzed legs through the exact, perfect motion of walking.
* '''Neuroplasticity''' — The biological magic behind rehab exoskeletons. When the robot physically forces the paralyzed leg to walk, sensory signals are sent back up the spine. The brain receives this data and slowly begins to physically rewire new neural pathways around the damaged brain tissue, eventually allowing the patient to regain biological control.
* '''Industrial Exoskeletons''' — Wearable devices deployed in factories (like Ford or Boeing). Often passive upper-body suits that provide mechanical support for workers who have to hold heavy drills above their heads for 8 hours a day, drastically reducing shoulder and back injuries.
* '''Military Exoskeletons (e.g., HULC)''' — Highly advanced, active suits funded by groups like DARPA. Designed to allow infantry soldiers to carry 200 pounds of armor and ammunition across brutal mountain terrain at a sprint, without destroying their knees or exhausting their cardiovascular system.
* '''Intention Detection''' — The massive software challenge. The exoskeleton must know you want to walk *before* you actually walk. If the robot pushes your leg a split-second after you move, it feels like dragging dead weight. The sensors must instantly read the microscopic muscle twitches to predict and perfectly sync with human intent.
* '''Electromyography (EMG) Sensors''' — Stickers placed directly on the human skin that read the electrical signals sent from the brain to the muscle. Advanced exoskeletons use EMG to read the electrical command to move, allowing the robotic motors to fire at the exact millisecond the biological muscle fires.
* '''Kinematic Compatibility''' — The architectural challenge of designing the suit so its mechanical hinges align absolutely, perfectly with the chaotic, complex, sliding joints of the human knee and hip. If they misalign, the robot will brutally twist and break the human's bones.
* '''The Metabolic Cost''' — The primary metric of success for an exoskeleton. The suit is only successful if wearing it actually reduces the amount of oxygen and calories the human burns to complete a task.
