Intelligent Wheelchair Bed (IWB) is an important direction. And it is also one of the most active research direction in the robot field. In this work, the obstacle avoidance algorithm based on the Artificial Potential Field (APF) using ultrasonic sensors is proposed and realized in order to achieve the real-time and continuing obstacle avoidance for the IWB. The IWB can keep on detecting the environment...
Real-time obstacle avoidance is one of the key issues to successful applications of mobile robot in the complex and unknown environment. However, now commonly used local obstacle avoidance strategies have some deficiencies. For example, VFH is superior to path planning, but it is not optimal when encountering with a obstacle which suddenly appears in front of the mobile robot. By the development of...
