@zhangshuoxiao 是不是小车的udev规则没有配置好，出现的错误是什么

@weijiz 老师，我在使用cartographer建图过程中感觉没有进行闭环，建出的图还是斜的，请问应该怎样操作？

@xiaoqiang 谢谢您啦

@Arieszzh 根据舵机上的型号标签，如果相同则可以替换，不同的话可以淘宝一款相同型号的电机进行替换

你好 还是这个错误 ERROR: cannot launch node of type [audio_capture/audio_capture]: can’t locate node [audio_capture] in package [audio_capture]

@Taiping 在 原装和国产ps3手柄ros驱动程序 中说：

Bluetooth: hci0: command 0x0c1a tx timeout

有16.04的机器吗，试试16.04。同时lsusb看一下蓝牙设备

@Jockey
这个是ros的标准日志。可以搜ros log看看。

监听话题

rostopic echo /galileo/cmds

@youngestuser 运行clinfo可以查看信息。

mount: mounting /dev/loop0 on //filesystem.squashfs faild: no such device
can not mount /dev/loop0 (/cdrom/casper/filesystem.squashfs) on //filesystem.squashfs

@ranzhu-uestcer rviz里面可以把点云显示大小调大一些，这样视觉效果上会更有稠密感

@rongrong1314 证书获取及使用方法

@weijiz -X不行,vnc就可以了,谢谢大佬

@terminal 超声波当作红外传感器处理。比如放在前方的超声波距离小于某值就停止前进。放在后面的超声波距离小于某值就停止后退。
