1 简介
移动机器人路径规划一直是一个比较热门的话题,A星算法以及其扩展性算法被广范地应用于求解移动机器人的最优路径.该文在研究机器人路径规划算法中,详细阐述了传统A星算法的基本原理,并通过栅格法分割了机器人路径规划区域,利用MATLAB仿真平台生成了机器人二维路径仿真地图对其进行仿真实验,并对结果进行分析和研究,为今后进一步的研究提供经验.
2 部分代码
function varargout = A_GUI(varargin)
% A_GUI MATLAB code for A_GUI.fig
% A_GUI, by itself, creates a new A_GUI or raises the existing
% singleton*.
%
% H = A_GUI returns the handle to a new A_GUI or the handle to
% the existing singleton*.
%
% --- Executes on selection change in popupmenu1.
function popupmenu1_Callback(hObject, eventdata, handles)
% hObject handle to popupmenu1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
row = [15 20 25 300];
global n_r
n_r = row(get(handles.popupmenu1, 'value'));
% Hints: contents = cellstr(get(hObject,'String')) returns popupmenu1 contents as cell array
% contents{get(hObject,'Value')} returns selected item from popupmenu1
% --- Executes during object creation, after setting all properties.
function popupmenu1_CreateFcn(hObject, eventdata, handles)
% hObject handle to popupmenu1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles empty - handles not created until after all CreateFcns called
% Hint: popupmenu controls usually have a white background on Windows.
% See ISPC and COMPUTER.

set(hObject,'BackgroundColor','white');
end
% --- Executes on selection change in popupmenu2.

function text5_Callback(hObject, eventdata, handles)
% hObject handle to text5 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Hints: get(hObject,'String') returns contents of text5 as text
% str2double(get(hObject,'String')) returns contents of text5 as a double
