Design and Construction of a Low-Cost Ankle Exoskeleton for Neurorehabilitation System

This article presents the design and construction of an ankle exoskeleton intended for neurorehabilitation therapies, addressing the challenge of the high cost of such devices. The research proposes a low-cost exoskeleton, utilizing techniques such as 3D printing and the use of economical electronic components. The result is a modular design composed of three fundamental parts, operated by two servomotors that assist in dorsiflexion and plantar flexion movements of the foot. This exoskeleton has undergone several proof-of-concept tests with a BMI architecture, identifying areas for improvement that will serve as the basis for future iterations. This approach promises to make rehabilitation technology more accessible and efficient, facilitating its adoption in clinical and research settings.
