我正在尝试使用以下公式为给定的对象绘制一个势场:
U=-α_goal*e^(-((x-x_goal )^2/a_goal +(y-y_goal^2)/b_goal ) )
使用以下代码
# Set limits and number of points in grid
xmax = 10.0
xmin = -xmax
NX = 20
ymax = 10.0
ymin = -ymax
NY = 20
# Make grid and calculate vector components
x = linspace(xmin,
我用虚拟势场来控制一组机器人在二维环境中的运动,它们的位置由x和y坐标的矩阵给出。虚拟势场依赖于多个变量,其中之一是机器人间的距离.下面给出了我的代码的一个简短(非常简化的)示例。
x = sym('x',[4 2]); % four robots with x and y coordinates
xd = sym('xd',[1 2]); % a single destination
F = sym(ones(4,1)); % one potential function for each r
我需要一些帮助来启动djangoappengine测试程序。我按照上的说明操作,但是当我运行./manage.py runserver时。当在项目目录中时,我得到以下错误:
