我正在遵循DroneKit-Python中的getting started指令,在VM中设置DroneKit。为了让自己更轻松,我从Setting up SITL using Vagrant开始。但是,我无法弄清楚如何让SITL运行并从示例脚本中与它进行对话。
我做了什么:
通过执行以下操作在“Setting up on Linux”中进行了测试:
param load ../ Tools / autotest / copter_params.parm
param set ARMING_CHECK 0
注意 - 不是“STABILIZE>”提示在我的MAVProxy提示符中可见。 这些成功(似乎是)成功
vagrant ssh
到
打开我对虚拟机的提示。我安装了dependencies as described here(修好后) pip规范):
sudo apt-get install python-pip python-numpy python-opencv python-serial python-pyparsing python-wxgtk2.8
然后是MAVProxy
sudo pip install MAVProxy
然后droneapi(注意,必须使用“sudo”安装)
sudo pip install droneapi
然后从命令提示符(vagrant @ vagrant-ubuntu-trusty-32:/ vagrant / ArduCopter $)获得git clone并导航到演示:
git clone http://github.com/diydrones/droneapi-python.git
cd droneapi-python/example/small_demo
我使用“mavproxy.py”(通过USB进行Linux VM通信的正确类型)启动了MavProxy。得到以下信息:
Auto-detected serial ports are:
/dev/ttyS31
/dev/ttyS30
...
/dev/ttyS1
/dev/ttyS0
Logging to mav.tlog
libdc1394 error: Failed to initialize libdc1394
最后,尽管有上述错误,我还是尝试加载并使用该模块。
MAV> module load droneapi.module.api
MAV> DroneAPI loaded
Loaded module droneapi.module.api
api start small_demo.py
MAV> Exception in APIThread-0:
Traceback (most recent call last):

File "/usr/local/lib/python2.7/dist-packages/droneapi/module/api.py", line 593, in <lambda>
APIThread(self, lambda: execfile(args[1], g), args[1])
...
注意“MAV&gt;”提示不是“手动&gt;”如文档中所列。
问题是“为什么这会失败,我需要做些什么才能让它发挥作用?”我猜测问题是SITL实际上并没有运行。
谢谢!
答案 0 :(得分:1)
从主机操作系统中的ardupilot代码的新结帐开始。
droneapi-python将安装,但让我们获取示例脚本:
ardupilot$ git clone http://github.com/diydrones/droneapi-python.git
打开流浪盒:
ardupilot$ vagrant up
按照"Setting up SITL using Vagrant":
中的说明启动SITLardupilot$ vagrant ssh -c "sim_vehicle.sh -j 2"
会有很多输出,但最后我看到了:
