In order to reduce the burden of caregivers, a target following and obstacle avoidance embedded intelligent wheelchair is designed and implemented with fuzzy control. The location of persons and obstacles around wheelchairs can be detected in real time by laser scanning radar, and the target can be identified accurately combining RSSI localization method. The position error of the target person and the obstacles relative to the wheelchair is used as the input. The fuzzy control rules are established by using the fuzzy control method, and the comprehensive decision of following and avoiding obstacles is made to control the translational velocity and rotational velocity of the wheelchair .Experiment shows that the wheelchair can identify target person and obstacles, meanwhile it can follow the target and avoid obstacles accurately.
