EXOSKELETON
A passive, research-grade wearable exoskeleton engineered to capture, classify, and translate human gait patterns into actionable biomechanical data — enabling the next generation of personalized powered rehabilitation systems.
PRECISION
SENSING
PLATFORM
Avatar integrates absolute encoders at the hip and knee joints with multi-axis IMU sensors across the lower limbs and torso. Together, they provide a complete kinematic signature of each individual's gait cycle — capturing angle, displacement, velocity, and movement intent in real time.
CAPTURED
GAIT MODES
Avatar is validated across the full spectrum of daily life locomotion patterns, enabling comprehensive biomechanical profiling for both healthy and sub-healthy populations.
AVATAR
WORKFLOW
Avatar's core innovation lies in mapping the sub-healthy user's gait initiation signals onto the normative healthy gait cycle. These onset triggers — extracted from the Avatar data stream — serve as the AI training corpus for commissioning a bespoke powered exoskeleton, ensuring the assistive output mirrors natural, healthy locomotion rather than compensating for it.
This preserves the integrity of the unaffected limb and prevents the accelerated joint degeneration — affecting the contralateral knee and hip — that is commonly observed in long-term unilateral compensation strategies.

PROTECTING
THE
HEALTHY SIDE
In unilateral impairment cases, patients instinctively over-rely on their stronger limb. Without intervention, this compensation pattern accelerates degenerative joint disease in the knee and hip of the healthy side — a clinical trajectory that unfolds silently over 5 to 10 years.
Avatar's gait mapping and structured motion-intent data help restore a more symmetric movement pattern from the beginning of deployment. The goal is not only to record gait behavior, but also to support future powered assistance that protects the healthy limb while reducing long-term compensatory stress.
