Providing Knee Movement Assistance using Android and IOT

Aging in living beings is a natural process and with aging one encounters challenges with walking or standing for long hours. Obsolete solutions like walking sticks do not provide satisfactory and effective solutions permanently neither can they be integrated with smart features to help in physical ailments. This paper aims to provide a knee brace made up of aluminium along with the device built using lead screw mechanism attached to the legs for the movement of the legs. This is made possible using 12V High Torque DC Geared Motor with 30 RPM and 21 Kg /Cm Rated torque. Lead Screw Mechanism uses the power generated by the motor to facilitate movement. Arduino Uno with the microchip ATmega328P controls the motor. The Bluetooth module (HC-05) helps in connecting the microcontroller to the Walk-Easy mobile app created. The Walk-Easy app allows the user to sit or stand using either buttons provided or through voice command. The Mobile App is integrated for user convenience, through which the movement is assisted as desired by the user. The main goal here is to realise a device to overcome these problems and provide effective solution to the knee related problem
