RETRACTED: An enhanced obstacle avoidance and path correction mechanism for an autonomous intelligent robot with multiple sensors (Retracted Article)

An enhanced obstacle avoidance and path correction mechanism with behavioral strategy is developed by using three ultrasonic sensors and one compass sensor for a small-size humanoid autonomous intelligent robot which can detect environmental information and correct the path automatically with 4 degrees-of-freedom to perform three types of walking motions, walking forward, turning left and turning right. A field test is conducted to verify the proposed mechanism with three experiments. The results show that the proposed mechanism outperforms previous research of robot obstacle avoidance in moving time, turning times and moving steps.
