Need a hand? This little robot arm is designed to empower people afflicted with physical disabilities, giving them back the dignity of feeding themselves. The robot arm will be useful for people suffering from ALS, cerebral palsy, MS, Parkinson's and brain or spinal injuries.

Created by the robotics firm Desin, Obi features four separate bowls for food and a robotic arm with a spoon that can learn the delivery location after being shown once by a caregiver. It has portion control settings, interchangeable spoons (a large and a small) and a spill-proof surface for easy clean up. Both, the spoons and the bowls, are dishwasher and microwave-safe.

How does it work? One button moves the arm between the bowls, and another selects that food, dips the spoon in and brings it up to the diner's mouth. The Obi arm will provide up to two to four hours of eating time for each charge of its internal batteries.

Device is available for US$4,500, which includes the plate, placemat, a large and small spoon, charging cable and user documentation.
