This paper presents an implementation of trajectory planning method while considering velocity constraints for a two-wheeled mobile robot (TMR) on Xenomai. A Bezier curve is utilized to make an S-curved path. A convolution operator is used to generate a velocity profile of the travel distance of the planned path while considering the velocity constraints of the TMR. The trajectory planning and ...

This paper aims to design and generate a loft surface using three distinct curves (Hermitee cubic curve, straight line, quadratic Bezier curve) analyze its characteristics in isotropic space type-2-Bishop. Moreover, the surface's 1st 2nd - fundamental forms were investigated. In addition, their Gaussian, mean, second Gaussian curvatures I3 computed first type-2-Bishop curvatures. Furthermore, r...

A handrail is widely applied to assist the standing up motion of elderly and disabled people. We developed the power assisted handrail which aim to synchronize with user's standing up motion. The handrail system consists of a linear actuator, a PC for control. The trajectory of handrail could design which is based on Bezier curve. We had an experiment to confirm the functionality of this system...

We present an obstacle avoiding path planning method based on a Voronoi diagram. We use a tactical visibility measure to obtain the shortest path length with the lowest local probability to be discovered based on the map topology. A Voronoi-based navigation mesh for finding the shortest smooth path with the lowest visibility along the path is used. The piecewise linear rough path in the Voronoi...

The creative industries have become the government's attention for contributing to economic accretion. But due lack of artistic creativity and appeal, evolution craft section is not optimal. So that it was needed a variations relief items increase attractiveness. In general, industrial objects design are still limited space geometry or Bezier curve degree two. Therefore, curves selected modifie...

This is the first one in a sequence of several papers dedicated to the development of applications of Euler Beta-function B-splines (BFBS) to Computer-aided Geometric Design (CAGD) and, in particular, for geometric modelling of parametric curves, surfaces and volume deformations. This study is an analogue of the study conducted in [12, 10] for the case of expo-rational Bsplines (ERBS). An impor...

Aiming at complex road conditions and difficult path planning of semi-structured roads in a park, robust method based on sequential quadratic programming (SQP) algorithm optimization is proposed. Firstly, an improved vector field histogram (VFH) used to determine the optimal passable area, then determination target state given area; Secondly, according starting point state, description obstacle...

According to the requirements for tower crane welding robots, precisely planning the welding trajectory is essential. The optimal model for the least-time trajectory planning for the robot is established by Bezier curve, which has the characteristic of sub-section processing. With the consideration of constraints such as joint angular velocity and acceleration, the specific operation steps of g...
