简介
在这个例子中,我们将使用softMC模拟器来创建Delta机器人,从终端观看一些参数,最后用roboDK运行机器人。
我们从roboDK库中选择Delta机器人,机器人参数:
Rbig = 110 [mm]
L1 = 100 [mm]
L2 = 270 [mm]
Rsmall = 40 [mm]
Gear 1:10
典型速度是 18,000/10 [deg/sec] 3000 [RPM]
典型最大速度 30,000/10 [deg/sec]
典型加速度/减速度 720,000/10 [deg/sec]
典型最大加速度/减速度 900,000/10 [deg/sec]
典型加加速度 2,160,000/10 [deg/sec]
典型最大加加速度 2,700,000/10 [deg/sec]
注意:
工具坐标值为: tool = #{0,0,15,0}
运行softMC SIM
使用VM运行softMC模拟器,mc作为登录系统登录和密码,输入ifconfig找到softMC模拟器IP地址,在下面的例子中是192.168.56.103
运行ControlStudio
运行ControlStudio,并确保运行相应的固件版本,在下面的例子中,我们运行固件0.4.17.2-C2
创建并运行CONFIG.PRG文件
配置器不生成CONFIG.PRG文件,这是必需的文件。
最简单的CONFIG.PRG文件将如下所示:
Sys.NumberAxes = 4
program
Sys.Name = "DVG_Delta"
Print "system is running - " ; Sys.Name
Sys.DoubleFormat = 1 ; viewing the watch number
end program
注意:由于Delta机器人需要4个轴,所以Sys.NumberAxes至少为4。
在打开配置器之前,请确保通过使用"Save and Load"将其上传到softMC并在终端中发送">reset all"来运行CONFIG.PRG文件。
运行配置器打开新项目
从ControlStudio运行配置程序并打开新的Project
重要注意事项:
- 您在模拟中运行时,您在Buses文件夹下看不到任何驱动器
- 确保能看到4个轴(A1 A2 A3 A4)
创建新文件夹
现在我们将创建我们的文件夹和我们的配置文件,我们将使用"Save As"创建"New"文件夹,并将我们的配置文件命名为Delta。
配置驱动器和轴
定义驱动器
由于我们使用softMC模拟器,我们没有任何驱动器,可以跳到下一步
定义轴
点击第一个轴,其配置窗口将显示:
- 选择"Axis Type"。Delta选择"Rotary Gear"。
- 设置正确的减速比。 我们该值保持为1
对每个使用的轴重复最后一步。
提示:
如果您有类似的轴,您可以是用鼠标单击轴复制整个轴执行所有设置。
轴的配置窗口有一些选项卡。 "Properties"选项卡允许设置轴属性。 为每个轴适当设置以下属性
重要: 这些值是减速后的最终值
对于模拟机器人,将"Simulated Axis"属性更改为"True"
velocity is 18,000 [deg/sec] 3000 [RPM]
max velocity is 30,000 [deg/sec]
Acceleration/Deceleration 720,000 [deg/sec]
Max Acceleration/Deceleration 900,000 [deg/sec]
Jerk is 2,160,000 [deg/sec]
max Jerk is 2,700,000 [deg/sec]
Position error max 10
创建Delta机器人
右键单击组图标,然后选择添加组
选择 Robot
组名称 DELTA
选择 delta xyzr [rrrr]
单击所有四轴,注意框架颜色从红色变为绿色。
综合
此选项卡允许切换链接到组的轴,并更改轴属性,因为您有多于4轴。
耦合
- 对于Delta机器人,不应定义耦合矩阵(定义电机轴是否仅旋转特定关节或多于一个关节。)
- 每个轴的关节位置限制。
属性
此选项卡允许设置机器人属性,如:位置限制,速度限制,加速限制等
注意:
- 确保在simple/Cartesian表“PeMax”(-->delta.pemax=10)中将位置误差设置为最大值10 (-->delta.pemax=10)
配置
该选项表有3个子选项表:
- 确保将工具Z轴设置为15以适应RoboDK(-->delta.tool=#{0,0,15,0})

Delta参数
这里我们设置Delta机器人的机械参数:
Rbig = 110 [mm]
L1 = 100 [mm]
L2 = 270 [mm]
Rsmall = 40 [mm]
建立&配置
现在我们已经准备好生成安装和通信文件,并在softMC上运行它们,点击"Build
&Configure"

Build & Configure 前 | Build & Configure 后 |
---|---|
关闭配置器
创建解决方案
要创建解决方案,我们必须执行以下操作:
- 打开由Build&Configure创建的Project(apj文件)
- 将其另存为解决方案(asn文件)
- 将Config.prg从控制器添加到PC
- 使用资源管理器将任何用户预览程序复制到文件夹
- 将文件添加到解决方案树
添加监视
我们可以从终端查看拥有的轴
-->?grouplist
DELTA:A1,A2,A3,A4
添加启用Delta机器人位置反馈和XYZR值的监视。
运行机器人
现在运行机器人
现在我们可以运行机器人
-->Delta.en=1
-->move delta {0,0,0,20}
重新循环运行机器人
执行以下操作:
- 运行并启动softMCSIM
- 运行ControlStudio并连接到您的softMCSIM
- 打开您的"Delta" 解决方案
- 双击程序文件"StartPRG.PRG"
- 点击图标"Save and Load"
Delta 机器人就绪
用roboDK运行机器人
打开TCP / IP服务器以使用RoboDK
保存加载并运行SERV4DEL.PRG,确保您在ControlStudio消息日志中看到"socket 2 is set"
提示:使用Windows键+左边的错误,在左半边的窗口上得到ControlStudio。
