Abstract: An assistive robotic arm for people with severe disabilities is presented in this paper. Its user interface using eye movements consists of a Web camera, computer, and microcontroller with display unit. Using the robotic arm system, we performed two experiments: (1) transferring water task and (2) eating soup task. It was found from the experimental results that the assistive robotic arm system could stably and appropriately transfer more than 82 % of water and 86 % of soup to the respective positions.
