An assistive robotic arm for helping feed people with physical disabilities of the extremities is presented in this paper. In order to detect foods on a plate, HOG based food detectors were created and implemented in our robotic arm system. The system consists of a 6-axis robotic arm, Web camera, laptop computer, and microcontroller.

In this paper, an image processing method using CMOS camera was applied to an assistive system to care for bedridden people. It was experimentally demonstrated that 2-dimensional position tracking of the experimental subject's mouth was performed using image processing. Furthermore, 3-dimensional position tracking of the subject's mouth was measured using stereo matching measurement.
