Abstract: Rolling contact has been used by robotic devices to drive between configurations. The degrees of freedom (DOFs) of rolling contact pairs can be one, two, or three, depending on the geometry of the objects. This paper aimed ...

Abstract: The complex kinematic structure of a human thumb makes it difficult to capture and control the thumb motions. A further complication is that mapping the fingertip position alone leads to inadequate grasping postures for ...

Abstract: Exoskeletons can assist wearers to relearn natural movements when attached to the human body. However, most current devices are bulky and heavy, which limit their application. In this paper, we integrated type and dimensional ...

Abstract: Recently, robotic assistive leg exoskeletons have gained popularity because an increased number of people crave for powered devices to run faster and longer or carry heavier loads. However, these powered devices have the ...

Abstract: This paper describes the AmBot, a centipedeinspired amphibious robot for monitoring the SwanCanning River, the most important estuary system in Western Australia. The major challenge in developing such a robot lies in that ...

Abstract: The design of the intake port plays a critical role in the development of modern internal combustion (IC) engines. The traditional method of the intake port design is a timeconsuming process including a huge amount of tests ...

Abstract: Particle image velocimetry (PIV) system was used to measure the tumble structure of the incylinder airflow in a fourvalve optical gasoline direct injection (GDI) engine. The tumble ratio was controlled by a flap in the ...
