Serial Connection to Hokuyo from Master
Hi,
I am currently getting the error:
[ERROR] [1531729856.715593296]: Error connecting to Hokuyo: Could not open serial Hokuyo:
/dev/ttyACM0 @ 115200
could not open serial device.
Initially, after encountering this problem, I was able to resolve it by adding myself to the dialout list as suggested: https://answers.ros.org/question/2866... I was able to view the data from the Hokuyo after doing this.
I am now trying to access the Hokuyo from a different machine. On the drone (where the Hokuyo is connected), I changed ROS_MASTER_URI and ROS_IP to match the PC. On the PC, I then ran:
$ roscore
$ ssh drone-user@drone-IP
I am able to run '$ rostopic list' correctly. However, after typing '$ rosrun urg_node urg_node', I receive the error mentioned above.
Any help is greatly appreciated.
Thanks,
Justin
