MATLAB机器人简单正逆运动学GUI演示_matlab机器人运动演示

1、前言：机器人正逆运动学可以直接查看机器人工具箱的函数ikine和fkine,以及直接用teach（）函数演示正逆运动学。

如下：

L_1=20;
L_2=50;
L_3=40;
L(1)=Link([0 L_1 0 pi/2]);
L(2)=Link([0 0 L_2 0]);
L(3)=Link([0 0 L_3 0 ]);
Robot=SerialLink(L);

teach(Robot)

2、当在GUI中主要是数据输入求解的演示：（下面直接贴出代码），主要看

btn_Forward和btn_Inverse    %GUI的fig文件可以按照下图自己建立，也可直接下载我的资源：

function varargout = SimpleRobotGui(varargin)
% SIMPLEROBOTGUI MATLAB code for SimpleRobotGui.fig
%      SIMPLEROBOTGUI, by itself, creates a new SIMPLEROBOTGUI or raises the existing
%      singleton*.
%
%      H = SIMPLEROBOTGUI returns the handle to a new SIMPLEROBOTGUI or the handle to
%      the existing singleton*.
%
%      SIMPLEROBOTGUI('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in SIMPLEROBOTGUI.M with the given input arguments.
%
%      SIMPLEROBOTGUI('Property','Value',...) creates a new SIMPLEROBOTGUI or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before SimpleRobotGui_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to SimpleRobotGui_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
