Design of upper limb exoskeleton for partially paralyzed patients

Human hands are essential in activities of daily dwelling, with a ramification of functions including touching, feeling, preserving, grasping, typing, handwriting, moulding, etc. however, disability from stroke or harm remains to be the main purpose of impairment global. Medical evidence suggests that repetitive physical activities and strengthening sports are vital to regain motor function and improve the first-class of lifestyles of patients stricken by hand impairments. The hand is part of the extremity of a human positioned at the distal phase of an arm or forelimb.

Our fundamental aim is to build such an exoskeleton assisting hand to conquer the incapacity hassle of the human hand with the usage of microcontrollers, microprocessors, and motors. In this challenge we have tried to perform our intention with the use of FSR sensor, relay module, equipment motor primarily based Actuator (excessive Torque) which cannot be viable without amassing an understanding of these devices. Getting statistics perfectly in time through sensors is a project that we have taken on, and accurate implementation is also a challenge that was taken on successfully.

Top 3 Learnings

1. We focussed to aid the upper limb impaired patients of Dhaka.
2. We thought of making a prototype with resources available in Dhaka.
3. We wanted to reduce the dependency ratio on the economy.
