The forced swim test (FST) is a method for measuring the pharmacological effects of antidepressants or changes in stress-evoked behavior in laboratory animals such as rats and mice. However, traditional manual or automatic measurement methods using video recorded at 30 fps (frames per second) have not always been accurate and objective because laboratory(More)
In this paper, we propose an automatic behavior recognition algorithm for laboratory mice to determine their typical model behaviors and hence detect the degrees of diseases via animal testings for behavioral pharmacology. The algorithm can quantify several model behaviors of mice by detecting the repetitive motions of fore or hind limbs at several hertz;(More)
Conductive rubber material has been widely investigated as a sensor and transducer material due to its high piezoresistive, conductive properties. In this paper, we report on a flexible tactile sensor which is based on conductive rubber filled with carbon black. Firstly, a physical model related linear elasticity mechanics and franklinic analogue method is(More)
In this paper, we develop a novel robotic arm wrestling system integrated with mechanical arm, elbow/wrist force sensors, servo motor, encoder, 3-D MEMS accelerometer, and USB camera. The arm wrestling robot (AWR) is intended to play arm wrestling game with real human on a table for entertainment. The designing scenario of the prototype model's hardware is(More)
A novel real-time motion analysis system was developed for detecting the scratching behavior of laboratory mice in long-time experiments, which enables automated behavior quantification for new drug development in diseases such as atopic dermatitis and so on. This system can detect quick movements of laboratory mice, such as scratching, by introducing a(More)
This paper presents a novel 2 DOF robotic arm wrestling system integrated with mechanical arm, elbow/wrist force sensors, servo motor, encoder, 3-D MEMS accelerometer, and USB camera. The arm wrestling robot (AWR) is used to play arm wrestling game with human for entertainment. Based on the force testing equipment, we acquire the data of surface(More)
Manual detection in photo finishing is subjective and of low efficiency. In this study, an automatic detection method is proposed to detect the finish line on the photograph. The object is abstracted by a self-adaption background substraction algorithm based on the specific feature of line scan image. Then an estimative target region mehod is proposed to(More)
By capturing three-dimensional motions of small markers on the heart of a small laboratory animal with 1000 fps stereo images, we realized a cardiac motion analysis system to quantify the rate of change in the myocardial area of its heart, which indicates the myocardium's activity for a rhythmic expansion/contraction motion in a local area. Using this(More)
