The AE-03 is a professional wearable lower limb exoskeleton rehabilitation robot for motorized hip, knee and ankle joint gait training.

Key Features —

• Motorized Lower Limb Joint Actuation — Powered Gait Assistance : The AE-03's exoskeleton frame integrates electric motors at the hip and knee joints — providing the powered mechanical assistance that enables patients with paralysis, severe paresis, or significant lower limb weakness to perform complete, biomechanically correct gait cycles. 

The motorized joints provide:

• Hip joint actuation: Controlling hip flexion and extension to drive the swing and stance phases of the gait cycle.
• Knee joint actuation: Controlling knee flexion during swing and knee extension during stance — the two most clinically critical joint movements for functional gait.
• Coordinated bilateral movement: Both lower limbs are guided through the gait cycle in synchrony, maintaining the bilateral temporal coordination essential for physiologically normal walking patterns.

Multiple Training Modes — Covering the Full Rehabilitation Spectrum : The AE-03 supports multiple training modes that cover the full clinical severity spectrum from complete lower limb paralysis through to near-independent ambulation:

• Passive Mode: The exoskeleton's motors drive all lower limb joint movement — the patient's legs move through the correct gait pattern driven entirely by the robot without requiring any voluntary effort. This mode enables gait training for patients with complete lower limb paralysis or zero voluntary lower limb activation.
• Active-Assisted Mode: Sensors detect the patient's voluntary movement intention — any voluntary effort to move the lower limbs triggers or amplifies the exoskeleton's assistance, with the robot contributing only the additional force needed to complete the movement. This mode directly reinforces voluntary motor commands with mechanical assistance.
• Active/Resistance Mode: As the patient's voluntary lower limb function recovers, the exoskeleton can transition to providing resistance against voluntary movement — training the patient's recovering lower limb muscles to overcome the exoskeleton's controlled resistance rather than simply following its assistance. This progressive resistance mode bridges the transition from exoskeleton-dependent gait to independent walking.

Adjustable Anthropometric Parameters — Fitting Every Patient The BZRH03's exoskeleton frame is fully adjustable to accommodate the range of adult patient body dimensions:

• Hip joint height adjustment — fitting patients of different overall statures
• Thigh segment length adjustment — matching the patient's femur length
• Shank segment length adjustment — matching the patient's tibia length
• Width adjustment — accommodating different hip widths and pelvic geometries

Safety Systems — Patient Protection During Unsupported Walking A mid-therapy failure is not just a technical inconvenience; it is a direct patient safety risk. The BZRH03 incorporates multiple safety mechanisms:

• Fall detection: Accelerometers and gyroscopes continuously monitor the patient's centre of gravity and postural stability — detecting fall events and triggering emergency joint locking to prevent uncontrolled collapse.
• Emergency stop: Physical emergency stop controls accessible to both the patient and supervising therapist enable immediate cessation of all joint movement.
• Joint range limiters: Hardware joint stops prevent the exoskeleton from driving joints beyond safe anatomical limits regardless of control system commands.
• Torque limiting: Motor torque output is limited to prevent application of forces that could cause joint injury.

Gait Parameter Control — Precise Clinical Prescription : Walking speed, step length, cadence, and assistance level are all adjustable — enabling the treating physiotherapist to prescribe specific gait training parameters matched to the patient's current rehabilitation stage. Progressive increases in walking speed, reduced assistance, and longer session durations are all quantifiable and reproducible.

Rechargeable Battery — Clinical Session Duration The AE-03's battery-powered operation enables wireless, untethered overground walking. The rechargeable battery system provides sufficient operational duration for standard clinical session lengths.
