Obi 3

DESCRIPTION

Obi 3 is a Medical-Robots from Desin. It is built for Medical-Assistance, Helping. Key figures: 3.2 kg, 240 min runtime, price $19,950, released 2025.

Obi 3 is the third generation of Desin's Obi, a robotic self-feeding device for people with upper-extremity mobility impairments, such as those living with ALS, cerebral palsy, muscular dystrophy, multiple sclerosis, Parkinson's disease, spinal cord injury, spinal muscular atrophy or amputation. It is a medical device intended to compensate for the function of a human arm during meals: with the momentary touch of a switch, the user chooses between four food compartments on its plate and commands when the robotic arm scoops a bite and delivers it to the mouth. It works with any switch that uses a 3.5 mm jack, including pressure, pad, light-touch, pillow and sip-and-puff switches, so it can be operated by any part of the body that can press one. A caregiver sets the delivery position by guiding the arm by hand in Teach Mode, and Obi automatically repositions food in a bowl after six scoops. The magnetically attached spoon flexes or falls off if met with force, and collision detection makes the arm stop and back away. Compared with the second generation, Obi 3 adds Patient Power-On by switch, a Reward Mode with a 30-second celebratory motion, delivery to the mouth up to 3 seconds faster, about 5 cm more horizontal reach in Teach Mode, in-bowl collision back-up for hard food pieces, and a new magnetic utensil adapter with small, classic and large spoons and a spork, also in red for users with low vision. It weighs about 3.2 kg, is smaller than a placemat, is water resistant and runs 3 to 4 hours on a rechargeable lithium-ion battery. Obi is an FDA Class 1 medical device (510(k) exempt) and CE marked, and is sold in more than 20 countries with a 12-month warranty.
