<table id="dg_equal" class="table-datagrid"></table> 设置可以编辑

要使表格 `#dg_equal` 可以编辑，需要确保以下几点：

1. 引入 EasyUI 的相关库文件，例如 `jquery.easyui.min.js` 和 `jquery.easyui.min.css`。
2. 引入 EasyUI 的编辑器插件，例如 `jquery.edatagrid.js`。
3. 在表格属性中添加 `editable: true`，例如：

<table id="dg_equal" class="table-datagrid" editable="true"></table>

然后，在 JavaScript 中初始化表格，并启用编辑模式，例如：

$('#dg_equal').edatagrid({
    url: 'get_data.php',
    saveUrl: 'save_data.php',
    updateUrl: 'update_data.php',
    destroyUrl: 'delete_data.php',
    columns: [[
        {field:'id',title:'ID',width:100,hidden:true},
        {field:'name',title:'Name',width:100},
        {field:'age',title:'Age',width:100,align:'right'}
    ]]
});

这样就可以将表格 `#dg_equal` 设置为可编辑状态了。

可以将机器人运动的目标点改为固定的圆周上的点，以实现运动轨迹为一个半径为3的圆。具体步骤如下：

1. 定义一个固定圆心为(0,0)、半径为3的圆，假设圆心角为theta。

2. 每次仿真时，将机器人的目标点设置为圆上的点(x,y)，其中x=3*cos(theta)、y=3*sin(theta)。

3. 每次仿真时，将theta增加一个固定值delta_theta，使机器人沿着圆周运动。

修改后的代码如下：
