In this paper, we present a control system based on embedded system according to the features of humanoid robot. First, the image captured by the vision system is recognized through the improved look-up table method. And then with a smooth gait planning of turning motion for humanoid robot presented, the next several motions for the robot can be proposed by the local motion planner based on the...

Flapping flight is more maneuverable than steady flight. It is debated whether this advantage is necessarily accompanied by a trade-off in the flight efficiency. Here we ask if any flapping motion exists that is aerodynamically more efficient than the optimal steady motion. We solve the Navier-Stokes equation governing the fluid dynamics around a 2D flapping wing, and determine the minimal aero...

This paper considers the problem of path planning for teams of mobile robots. It presents a decoupled and prioritized approach to coordinate the movements of the mobile robots in their environment. Our algorithm computes the paths for the individual robots in the configuration-time space. Thereby it trades off the distance to both static objects as well as other robots and the length of the pat...

Space manipulator systems having spacecraft actuators turned off, operate in free-floating mode, and exhibit nonholonomic behaviour due to angular momentum conservation. The system is underactuated and a challenging problem is to control both the location of the end effector and the attitude of the base, using manipulator actuators only. A developed path planning method that perform this task i...

Our algorithm computes the paths for the individual robots in the configuration time-space.

We studied the fields of nine nearby open star clusters based on the Tycho–2 catalogue. We determined membership probabilities for the stars in the cluster fields from the stellar proper motions and used the Tycho–2 photometry to compute the initial mass function (IMF) of the clusters from the main sequence turn-off point down to approx. 1M⊙. We found IMF slopes ranging from Γ = −0.69 down to Γ...

to evaluate off-label and off-nccn guidelines uses of antineoplastic drugs in a major chinese hospital.totally 1122 patients were selected from july to december 2011. then, the off-label and off-nccn guidelines uses of antineoplastic drugs were analyzed.in 798 of 1122 patients (71.12%), drugs were used for off-label. in 317 of 1122 patients (28.25%), the drugs were prescribed for off-label and ...

In this thesis a low cost motion capture approach is presented and applied to measure cyclists’ kinematics. The motion capture system consists of low cost hardware and custom developed software. Based on still-frame, off-the-shelf digital cameras, the method represents a solution which is accessible to the average athlete. With the exception of off-the-shelf digital cameras the total cost of th...

OBJECTIVE The purpose of this study was to design and implement a transducer to measure accurately the isometric elbow moments produced by individuals with tetraplegia. DESIGN The device needed to be insensitive to off-axis moments and proximal joint motions and be capable of being used over a wide range of elbow and shoulder positions in an outpatient clinic setting. BACKGROUND Measurement...

In ostriches, the toes are the only body parts that contact loose sand surfaces. Thus, toe interphalangeal joint motions may play vital biomechanical roles. However, there is little research on ostrich phalangeal joint movements while walking or running on sand. The results from the three-dimensional motion track analysis system Simi Motion show that gait pattern has no significant effect on th...
