A Self-care Assistive Robot for the People with Lower Extremity Dyskinesia

In order to help the people with lower extremity dyskinesia work and live in a better way, a self-care assistive robot is proposed in this paper. The robot mainly consists of a flexible moving chassis, an adjustable seat, a step training mechanism, a lifting arm and an electrical control system. Compared with traditional walking AIDS, such as wheelchairs, the ideal objective of the robot is that it can assist users to independently complete daily activities, such as getting in and out bed, going to the toilet, rehabilitation training, outdoor travel and shopping in supermarkets without the help of other people, so that users can basically take care of themselves and their living quality has been greatly improved. In particular, the user can perform all the operations with one hand alone, which is very beneficial for patients with hemiplegia. The experimental results show that, the principle prototype basically realized the functions of assistive standing up, sitting pose adjustment, assistive sitting down and step training, which laid a foundation for the further optimization work.
