2014-01-28 17:23:06 -0500 | marked best answer | Turtlebot with not the same model irobot I have two turtlebots which are of the 4XXX series. I need to define the port number and the baud rate. But, I do not know how to do this. The turtlebots are built around the 5XX and the i-create. Any advice would be nice, please. Thank You in Advance. :-) |
2014-01-28 17:23:01 -0500 | marked best answer | cannot get Julius to run properly I get this error message: read waveform inputStat: adin_oss: device name = /dev/dsp (application default) Error: adin_oss: failed to open /dev/dsp failed to begin input stream Everything seems to be working until it reads the mic, then error. It is in the Rear input of the desktop. It cannot open it. I tried the voice recorder program and it inputs and outputs fine. What do I do now?? Thanks in advance. |

2011-11-23 14:45:19 -0500 | commented answer | Can't access turtlebot through ttyUSB0 I am having the same darn problem that I had on the other one. I can pull up the file and make changes, but I cannot save the new file. |
2011-11-23 14:10:54 -0500 | commented answer | Turtlebot with not the same model irobot Remember I am an Absolute NOVICE at this. |
2011-11-23 14:09:16 -0500 | commented answer | Turtlebot with not the same model irobot I was FINALLY able to edit the file turtlebot_node.py. the self.sci-57K was the right baud rate. But, in order to change the file, I had to Copy it out of the OPT directory into HOME. But, after modding the file, it still seems to look at the old place and shows me USB0 as before. |
2011-11-23 14:02:58 -0500 | commented answer | problem with ubuntu and permissions Exactly how would I create a new launch file and set up my ports? |
2011-11-23 13:54:49 -0500 | commented answer | problem with ubuntu and permissions OK, I copied the whole ROS directory to my HOME directory. So, as you said, I can now change the file. After I was able to save the file. I tried to run the turtlebot software, but, it still showed tty, USB0 instead of tty,S0 like I changed it to in the file. I checked it and it was how I changed it |

2011-11-22 13:00:07 -0500 | asked a question | getting permissions I installed ROS on both the Robot (netbook) and the desktop computers after installing UBUNTU. I am running a roomba, but not a 5XX or a create. I just need to CHANGE the port settings. I tried to change a file by gedit turtlebot_node.py which was supposed to have the tty,usb0 inside. Once I changed it, it would not let me save it because I did not have permissions. I have read the manuals and tried every which way to change it. Once I can see the port on the roomba and the kinect, then I can start doing the turtlebot, etc. Any ideas welcome. |
2011-11-20 07:45:44 -0500 | asked a question | problem with ubuntu and permissions I have installed turtlebot on my robot and also on the desktop. I am using the software on a 4XXX roomba. The baud rate is the same as the turtlebot. But, the port is not the same. I have tried and tried to edit the turtlebot_node.py configuration file and it will not let me save it. It says I don't have permissions. When I try to change the permissions, it tells me that I am not the owner so i cannot change the permission. This happens on both the netbook AND the desktop. I am loss to what to do next. chmod and chown do not seem to work. |
2011-11-16 09:05:59 -0500 | marked best answer | How can I set the path so the programs are always found? I would suggest taking a look at the introductory tutorials - particularly configuring the ROS environment. That includes information on setting up paths. |
2011-11-07 11:19:24 -0500 | asked a question | How can I set the path so the programs are always found? so far, I have installed UBUNTU. I have installed ROS. I have installed various relative Programs like Turtle-bot, etc. When I try to run the programs, the ROS can't find the files. How can I set the path so the programs are always found? it seems that I am doing this the hardway. What is the easyway? |
2011-11-07 06:54:23 -0500 | marked best answer | Turtlebot with not the same model irobot if you look in the code you will see a call for setting the baud rate in turtlebot_driver.py... create the SCI interface with the desired baud (something like self.sci= SerialCommandInterface(tty, YOURBAUD)) which basically calls serial with the baudrate if you would like to change the baudrate and port at a higher level change the turtlebot launch file to use the desire port and baud rate. both parameters are exposed at the node level in turtlebot_node.py |
