机械抓安装

１．　机械抓驱动在ubuntu 16.04, ａｎａｃｏｎｄａ，ｒｏｓ环境中安装的.

由于机械抓是ｕｂｕｎｔｕ１４．０４版本，所以catkin_make之前，将内部文件做了修改

２．　anaconda 需要添加的库：

２．１　pymodbus库

下载地址为：https://github.com/riptideio/pymodbus

安装方法：

git clone git://github.com/bashwork/pymodbus.gitcd pymodbuspython setup.py install

２．２　pyserial库（pymodbus需要用）

下载地址：　https://github.com/pyserial/pyserial

安装方法：

　　　　在线的：conda install -c conda-forge pyserial

　　　　　　　或者：　pip install pyserial

由于本人网速超级慢，所以下载后安装的，安装方法

python setup.py install

３　安装ｓｅｏｍ

sudo apt-get install ros-ｋｉｎｅｔｉｃ-soem

４．　安装后的操作

插上机械抓ＵＳＢ

dmesg | grep tty

sudo chmod +777 /dev/ttyUSB1

然后运行：

ｒｏｓｃｏｒｅ

rosrun robotiq_c_model_control CModelRtuNode.py /dev/ttyUSB0

rosrun robotiq_c_model_control CModelSimpleController.py

５．　修改的命令
