Abstract

Rehabilitations by Brain Computer Interface (BCI) technology helps (DHS) and (ALS) patients eat, drink, and socialize by controlling head and neck movement. In this research the chosen model parallel robot configuration (3RSS) manipulator was designed using 3D printing technology from (PLA) material to give six main movements for the neck brace, were achieved quality, shape acceptability to used, reduction in cost, reduced manufacturing time, lightweight (1.8 kilogram) and wearable. This mechanism was also distinguished by the fact that only three servo motors were connected and six movements were obtained in the small working space between the shoulders and head, and its movement was controlled by brain signals (EEG) after filtering them, applying a specific algorithm to specify the type of movement required for the neck. The results showed specify positions 10 of the 16 electrodes in the brain that had the highest response to neck movements . Angles of neck rotation were obtained to the right and left (±40°), down and up (±20°), while flexion was to the right and left (±15°). Simulations and tests were conducted on three different materials, with the best material selected numerically, the robot's movements positions and angles were specify at every moment.
