The study of quadruped robots is an important branch of robotics. As is known to all, quadruped robots can go through the rough terrain easily and they are useful in field operation. Whether quadruped robot can interact softly with the environment is an important index to value its property. This paper presents the preliminary research of a quadruped robot, mainly focus on the mechanical design and...
Movement disorder in lower extremity has been a major concern for the elder worldwide. Early diagnosis and effective therapy monitoring is an important prerequisite to treat patients and reduce health care costs. Objective and non-invasive assessment strategies are an urgent need in order to achieve this goal. In this study, we apply a wearable, lightweight and easy applicable sensor based gait analysis...
Plantar pressure distribution and acceleration measurements are important to detect walking postures and states. This paper presents an in-shoe measurement and analysis system to do the detection. In-shoe information is acquired by the circuit board which is attached to the human's shank and transmitted to the remote receiver wirelessly. A real-time display and analysis software is developed. Experiments...
For the purpose of developing a comprehensive set of rehabilitation system, this paper presents a novel design of pressure sensing foot for lower limb exoskeleton. The pressure sensing foot measures plantar pressure and acceleration to give instruction of the contact between human foot and ground and reflects behavior of the wearer. Compared with previous works, the pressure sensing foot described...
In this paper, we present a method to plan gait for a four legged robot that we specially design for realizing stability locomotion. Gait is crucial to the four legged robot locomotion, especially when the robot intends to get through irregular terrains adaptively. Compare to six legged robot or more leg robot, four legged robot easily loses its stability and slip up. We firstly analyze the locomotion...
