PyBullet（六）UR5机器人手臂模型_pybullet导入ur5

申明：停更了一段时间hhhhh，真是不好意思。由于英国疫情比较严重，自20年12月中旬回国之后，在深圳找了6个月的实习，想等到英国疫情好了之后再回去继续完成博士学业。最近公司的项目在搞UR5机器人手臂的控制，打算分步简单的记录一下，方便以后回顾。本篇文章只是简单的记录下UR5机器人的模型结构（urdf文件）。 这次项目直接在win10系统上面跑的，和在虚拟机上下载 "PyBullet"是一样的：

pip3 install pybullet
1

下载和安装时间会比较长，做好心理准备。

如果嫌复制粘贴太麻烦可以直接下载，下载地址：UR5机器人的urdf文件

这其中有7个文件需要下载：

base.stl
shoulder.stl
upperarm.stl
forearm.stl
wrist1.stl
wrist2.stl
wrist3.stl
