Paralyzed Patient Assist Robot
Assistive robot concept for helping paralyzed patients request support and control simple tasks.
Overview
This assistive robotics project focuses on improving independence for paralyzed patients. The robot concept can support simple actions such as calling for help, moving small items, or controlling nearby appliances through accessible input methods. It emphasizes practical human-centered engineering rather than only mechanical complexity.
