Integrating Complete Locomotive Assistance and IoT-Based Health Care for the Disabled
While many hi-tech products available in the market aim at addressing different issues of the disabled, due to the sheer cost and inefficiency of such solutions, they have failed to reach the masses. This product is being developed with an intention to provide complete self-dependence to disabled people and the elderly in performing everyday work at extremely low cost. Locomotive assistance is provided by a customizable-accelerometer/voice command/IOT/touchscreen-enabled wheelchair, which can either be controlled by the disabled person himself, or by remote assistance (using IoT), supported by live camera feed. The personal assistant robot shall help in performing tasks like cleaning & mopping, moving objects like medicines, parcels, food, water, etc. This robot can be controlled by Voice control, RF module, or by Bluetooth interface (customizable) and shall optionally provide live camera feed too. The digital home aspect of the project shall automate the lighting & cooling. The door access, light, fan, entertainment system, power sockets, and other household appliances can also be controlled wirelessly using an IR remote. The emergency alert system shall work by manual control. This alert system shall notify the support teams in case of an emergency.
