Empowerment Through Design
Desin LLC / Obi
Eating is one of the most fundamental human experiences. The act of feeding oneself in the presence of others ties together families and is a fundamental means of participating in culture and community. For those who can’t participate, it’s a constant reminder that they are dependent on others for a basic source of their wellbeing. The intent of the Obi robot is to allow users with physical limitations to feed themselves and join in on this most basic human experience. The robot itself is a highly complex machine, so SF’s approach to the project was to maintain focus on creating a simple, friendly, and helpful user experience. Our entry into the program was to arm our startup client with consumer validation of the concept. Development work focused on two primary directions: packaging the mechanisms of the robot in an attractive non-threatening body, and creating a friendly, easy-to-use UX. The program also required attention to many details of form and behavior that would allow the robot to reliably pick up food and deliver it cleanly to the user.
Preserving the virtue of self-empowerment was the core of Sundberg-Ferar’s approach to designing the Obi feeding robot.
With six motors and complex control programming, the main challenge in designing the robot was to manage this complexity to provide a simple, friendly, and satisfying user experience. Hiding wiring and housing the complex system of motors in the feeding arm were a top priority, but smaller nuances, like creating a comfortable spoon shape, adding a lip to the bowl and designing movements to control drips were equally important to the overall experience. One of Obi’s most important innovations was to provide a means of “teaching” the robot where to place the spoon to feed the user. This was solved by implementing a touch sensor in the arm that would allow it to be easily moved to the correct position. Grasping and releasing the arm triggers Obi to loosen the arm for positioning, and to remember the released position as the feeding location. To validate our ideas SF conducted several rounds of consumer research and in-field testing. We worked directly with end users and home care providers to identify improvements and find nuances that would help the robot to perform better and be easier to use.
Designed as a modular platform with real-time interchangeable components, Dannar 4.0 can be configured with or without an operator cab, body enclosures, and platform decks. It is also interchangeable with work implements including forklift masts, dump beds, scissor lifts, water tanks, portable light units and interfaces with all standard Caterpillar, Bobcat, or John Deere attachments.

Demand for Obi has outgrown national borders and the product is now distributed in more than 20 countries. Obi also holds 10 US patents, and has been awarded both a place in the 2016 R&D Top 100, and the Gold Medal in the 2018 Medical Design Excellence Awards.
It is a rare and rewarding opportunity to contribute to a project that has the potential to positively impact the lives of so many. To some, Obi represents a reclaimed measure of their dignity; to others, it feels like a new super power. To those who assist this group of people, it is a small but meaningful respite and changes a needful task into an opportunity to interact and connect. May we all be so fortunate.
