But it does not work for me. Actually, I've already checked closed thread #2 and #6, but I am still confusing. \r\n\r\nMy situation is the follwoings:\r\n1. My PC and ev3 can communicate vis ssh.\r\n2. ultrasonic.launch works. I could see the value from ultrasonic sensor.\r\n\r\nI compiled every packages which provided in \"Hacks4ROS/h4r_ev3_ctrl \" in my PC. So, I am thinking that\r\nit is possible that when I run \"roslaunch motors.lauch\", \"h4r_ev3_manager\" in my PC is started. \r\n\r\nWhen I do \"rosnode list\", I can see \"/ev3dev/ev3_manager_node\", but the following command does not work.\r\nrostopic pub /ev3dev/OutPortA/command std_msgs/Float64 \"data: 5.0\" \r\n\r\nDo I need to modify \"motors.launch\" according to my environment? I need a hint. \r\n\r\nThank you.\r\n\r\nmd\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/Hacks4ROS/h4r_ev3_ctrl/issues/comments/400542228","html_url":"https://github.com/Hacks4ROS/h4r_ev3_ctrl/issues/11#issuecomment-400542228","issue_url":"https://api.github.com/repos/Hacks4ROS/h4r_ev3_ctrl/issues/11","id":400542228,"node_id":"MDEyOklzc3VlQ29tbWVudDQwMDU0MjIyOA==","user":{"login":"rongfeng-china","id":8527188,"node_id":"MDQ6VXNlcjg1MjcxODg=","avatar_url":"https://avatars1.githubusercontent.com/u/8527188?v=4","gravatar_id":"","url":"https://api.github.com/users/rongfeng-china","html_url":"https://github.com/rongfeng-china","followers_url":"https://api.github.com/users/rongfeng-china/followers","following_url":"https://api.github.com/users/rongfeng-china/following{/other_user}","gists_url":"https://api.github.com/users/rongfeng-china/gists{/gist_id}","starred_url":"https://api.github.com/users/rongfeng-china/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/rongfeng-china/subscriptions","organizations_url":"https://api.github.com/users/rongfeng-china/orgs","repos_url":"https://api.github.com/users/rongfeng-china/repos","events_url":"https://api.github.com/users/rongfeng-china/events{/privacy}","received_events_url":"https://api.github.com/users/rongfeng-china/received_events","type":"User","site_admin":false},"created_at":"2018-06-27T04:53:38Z","updated_at":"2018-06-27T04:53:38Z","author_association":"NONE","body":"Thanks, my lego can connect with PC with USB cable. I also wrote some scripts to control the motors. They are working well now.  Thank you!!\r\n\r\nI'm considering to use wifi rather than USB for connection. I tried two wifi adapters: 1. Realtek Semiconductor Corp. RTL8191SU 802.11n WLAN Adapter 2. Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter.\r\nI checked with 'lsusb' and the device can be detected. However 'ifconfig' does not show the wifi infomation. \r\n![screenshot from 2018-06-26 22-44-55](https://user-images.githubusercontent.com/8527188/41953545-8f9f6a06-7993-11e8-8244-c51f7b265d6d.png)\r\n\r\nI also tried to install the driver for rtl8191, but it seems very tedious and not successful. Have you tried wifi connection and could you give some more explanations? Thanks\r\n"}}
