An improved nonlinear dynamic inverse guidance law is proposed for the problem of UAVs collision avoidance in this paper. First, a method based on collision cone boundary is investigated for collision detection. Second, an improved nonlinear dynamic inverse guidance law, which can be applied to multiple initial angles and speeds, is designed to ensure the security of UAVs collision avoidance. In addition,...
As the complex anatomical structure of the maxillofacial region, operation in this area is of high hazard and difficult to implement. Thus, a multi-arm medical robot assisting maxillofacial surgery, which can improve surgical precision and reduce surgeons' strain, was proposed. Firstly, overview of the whole robot system is introduced. Then this paper focuses on the control system which mainly consists...
The safety of navigation of ro-ro passenger ships has been perplexing the shipping circles, while the problem of vehicle safe stowing and securing is an important factor that affects the safe transportation of ro-ro passenger ships. Some specifications are put forward in home and abroad on the research of safe stowing and securing of vehicle on board ro-ro passenger ships. However, it is lacking in...
We propose a novel boundary-following algorithm that works in conjunction with any potential function that is guaranteed to take the robot to the target. The potential field must not have any local minima but is not required to avoid moving too closely to the boundary. The proposed method has several advantages: a) The calculation of the C-space is avoided, which can be costly especially if the robot...
