Our path planner is divided into two phases: First, let the robot study its maneuvering environment before giving a task, and then based on the studied map the robot is able to generate a safe and smooth path to its desired goal by using our potential field based collision avoidance algorithm. The environment exploration is done by adopting reduced(More)
MOTIVATION Differential detection on symptom-related pathogens (SRP) is critical for fast identification and accurate control against epidemic diseases. Conventional polymerase chain reaction (PCR) requires a large number of unique primers to amplify selected SRP target sequences. With multiple-use primers (mu-primers), multiple targets can be amplified and(More)
This paper presents a trajectory planning strategy of a wheeled mobile robot in an obstructed environment. In order to sense its surrounding environment, the mobile robot is assumed to be equipped with a laser range finder. The potential field method is utilized to create force fields around obstacles and a goal. Look-ahead control is adopted to steer the(More)

—Wordline voltage generating circuit with high speed active mode and low power standby mode is proposed. In the active mode, two different ring oscillators with high clock frequency (f CLK) 170MHz, and low clock frequency (f CLK) 25MHz which is also the operating frequency of the entire circuit, are employed. The proposed circuit has a short response time(More)
