6 million people in India suffer from different locomotive disorders and there are no available technology to assist them. This hampers their day to day activities and one of most important would be having a meal independently. The specially challenged find the day to day tasks challenging and need to depend on others. People derive confidence from their sense of independence in the society.

This solution empowers the differently able to have their meals independently anywhere, bridging the gap between technology and disability.

Various attempts have been made to provide a feeder device which will assist or

help the physically disabled individuals to have their meal independently and

these devices are bulky and hence needs to be affixed at a single position and

cannot be carried from point to point where the patient/ physically disabled or the

end user is located.

US3907126 discloses a feeder apparatus for physically handicapped persons.

US5282711 discloses an assistive dining device, system and method for automatic

self operated self feeding.

Prior Art Research

1:

These existing devices and many more are bulky. Although these devices are essentially going to replace a personal caretaker, the user is still dependent on them. Here are few devices which take a different approach on taking on this challenge. These devices apart from feeding also act like as exoskeleton, building on the muscle memory.

Stable Slide Self-Feeding Support

LIFT-WARE

A lot of people relate this to liftware (now a Google owned company) helps stabilize unwanted hand tremor from Essential Tremor or Parkinson's Disease. Therefore this doesn't address to cerebral palsy

Another video which people can relate to is the one from this movie.
