UAV automatic take-off and landing safety issue has been one of the key techniques to restrict its development. In this paper, taking a three-wheel UAV for the subject, ground taxiing modeling and control scheme of taxiing taking-off are studied. The control law designing of taxiing lateral deviation correction and longitudinal control law with the elevator are put forward. Lateral control structure...
This paper presents a novel type of tree-climbing robot. The main parts of the robot are 2 vehicles, which are attached on the trunk of a tree and were stick tightly on the tree because of a holding device. A kind of spine array is distributed on the wheels, and the friction is enhanced. Static stress analysis shows that the robot can overcome gravity and can be attached reliably to the tree trunk...
Interactive control strategies have been widely used in many rehabilitation robotic devices. The distinctive feature of these strategies is that the patient can be encouraged to actively participant in the therapy program. In this paper, a novel adaptive impedance control method, which allows the patient to actively influence the robot movement trajectory, is presented. The control algorithm developed...
The implementation requirements are multiplex in equipment requirement demonstration, which leads to the flexible flows of equipment requirement demonstration. And the flexible flows have to achieve the corresponding contents. So the method designing the flexible flows of equipment requirement demonstration is proposed. Firstly, according to the characteristic of equipment requirement demonstration,...
Wireless Sensor Networks (WSNs) have gained worldwide attentions in recent years. Since WSNs can be conveniently deployed to monitor a given field of interest, they have been considered as a great long-term economic potential for military, environmental, and scientific applications etc. One of the most active areas of research in WSNs is the coverage which is one of the most essential functions to...
