Adaptive Multi-Input Robotic Feeder for Enhanced Accessibility and Independence

University of Pittsburgh researchers have developed a multi-input robotic feeding device designed to assist individuals who cannot use their arms to feed themselves. This innovative device features a robotic arm equipped with a spoon that can scoop food from multiple bowls using different input methods, including touchscreen control via an iPad and voice activation. The device aims to improve the independence and quality of life for individuals with disabilities by providing a reliable and versatile feeding solution.

Description

The multi-input robotic feeder consists of a robotic arm with a spoon at the end, capable of scooping food using various motions to ensure complete retrieval from bowls and prevent overfilling. The device offers two input methods: touchscreen control via an iPad and voice activation. These input methods provide flexibility and ease of use for individuals with different needs and preferences. The robotic feeder is designed to be user-friendly and adaptable, making it suitable for a wide range of users.

Applications

• Assistive technology for individuals with disabilities
• Feeding assistance in healthcare settings
• Enhancing independence for individuals with limited mobility
• Rehabilitation and therapy for spinal cord injury patients

Advantages

The multi-input robotic feeder offers versatile input methods (touchscreen and voice control) to accommodate different user needs, efficient scooping motions to ensure complete retrieval of food from bowls, and prevention of overfilling to minimize food loss during feeding. These features collectively improve the independence and quality of life for individuals with disabilities, making the device compatible with existing assistive technology systems.

Invention Readiness

The technology has been developed into prototypes, with one device using touchscreen control via an iPad and another using voice activation. The iPad-controlled device has been provided to a client, and the voice-activated device is currently in use at UPMC Mercy in the spinal cord rehabilitation unit. The technology is ready for further development and commercialization.
