2015-06-21 03:24:12 -0500 | marked best answer | permission denied when creating custom msg in rosserial I get the following error. But it did create Encoder.h in /usr/share/arduino/libraries/ros_lib/Encoder so I guess I'm ok? |
2014-01-28 17:26:56 -0500 | marked best answer | multiple clientservice in rosserial? I need multiple service clients on an arduino running rosserial. In setup() I have: nh.serviceClient(client1); nh.serviceClient(client2); Only the first is connecting. If I swap the order then client2 is the only one called. No error messages in either serial_node.py or by the Arduino. Anyone get multiple service clients to work? |
2014-01-28 17:26:54 -0500 | marked best answer | rosserial Device Lost Sync, restarting I'm using an Arduino 2560. Does anyone have any suggestions on how I can diagnose this? My total sketch size is 60k bytes. I won't include all the code since there's a lot but here's some relevant parts. At this point I have a touch screen menu and each part of the menu sets a global variable that tells me what the current menu page is and then I use a switch statement to branch off into individual loop functions. All works fine. One of the loop functions runs this: I've got 2 service clients and 1 publisher. From my understanding that's not too much. If I use rostopic echo /Analog when that part of the loop function is running sometimes it'll return results but usually it's nothing. I doubt it's the code below because it will timeout before I get to the menu that runs that. |
2014-01-28 17:26:40 -0500 | marked best answer | 'type' object is not subscriptable I have a node that is a service that lists wifi access points and their details. When I first run rosrun there's no errors. Then I make a service request and it says Error processing request: 'type' object is not subscriptable. I'm sure it's a basic Python error but I can't figure out what it is. Thanks! The relevant code: my .srv file: |
2014-01-28 17:26:32 -0500 | marked best answer | ros service client arduino not publishing There's no documentation on the ServiceClient rosserial_arduino script, hoping someone can give me a little help here. I have a Service server running and if I use rosservice call it works so I know the problem is with my Arduino script. It compiles and uploads to the Arduino correctly but nothing shows in the Service server in ROS. Here's the tcpip.srv file: Arduino script |
2014-01-28 17:26:32 -0500 | marked best answer | openni_launch problems with kinect and asus, electric and fuerte. I've tried getting openni_launch to work on Ubuntu 12.04 with fuerte and a Kinect, also on 11.10 with electric and Kinect and on 11.10 with an Asus Xtion Pro Live and now on a second computer running 11.10, electric and the Asus camera. I'm convinced that there's got to be something wrong with the package. I've followed the instructions to the letter. Latest attempt with 11.10, electric and Asus Xtion. Are there known problems? I've spent probably 40 hours trying to get it working and hired an experienced ROS developer who has probably 15-20 hours into trying to get it working. Are there known problems with it? Has the project been abandoned? |
2014-01-28 17:26:12 -0500 | marked best answer | kinect install instructions for electric not working http://www.ros.org/wiki/openni_kinect I've tried the apt-get install and the source based for electric on Ubuntu 11.10. When I run the following command it errors out. |
2014-01-28 17:26:08 -0500 | marked best answer | trouble subscribing to custom messages First ROS script, jumping into the deep end. I have an Arduino publishing data (it's working fine) to a topic called Adc. I'm trying to write a Subscriber to read that data and eventually write it to a CSV file. It compiles ok with no errors but shows nothing. The data types that are published are 5 different uint16s but when I tried "from std_msgs.msg import uint16) and then use uint16 below I get an error so I went back to String in the sample code. Am I on the right track here? |
2014-01-28 17:26:05 -0500 | marked best answer | Kinect camera not found with ROS Installed Ubuntu 12 and Fuerte first and couldn't get the Kinect camera to show up. Reinstalled Ubuntu 11.10 and Electric and stepped line by line through installation guide and installed it by using sudo apt-get install ros-electric-openni-kinect. When I tried to 'rosrun openni_launch openni.launch' I got permission errors from usblib (can't remember the exact error). Found the 55-primesense-usb.rules file and the permissions looked ok. Tried to then install all the OpenNI drivers directly from the website http://www.pansenti.com/wordpress/?page_id=1740 and now when I run 'rosrun openni...' I get this error. After running through all those steps when I run the example I get this. /x86-Release$ sudo ./Sample-Players 503 INFO New log started on 2012-06-11 19:15:24 636 INFO OpenNI version is 1.5.2 (Build 23)-Linux-x86 (Dec 28 2011 17:53:48) 680 INFO --- Filter Info --- Minimum Severity: UNKNOWN One or more of the following nodes could not be enumerated: I'm doing everything by the book and nothing is working. Any suggestions? I've been trying for 4 hours to get this camera working and am at my wits end. |
2014-01-28 17:26:05 -0500 | marked best answer | rosserial install with fuerte? Been trying to install rosserial with fuerte. Following the instructions here. http://www.ros.org/wiki/rosserial_arduino/Tutorials/Arduino%20IDE%20Setup BTW, someone needs to add a sudo to the first command. Took me about 10 minutes to figure that out. when I run rosmake rosserial_arduino I get this: mkdir: cannot create directory `build': Permission denied I tried chmod'ing the rosserial_arduino folder to 777 to see if that would fix it and it didn't. Any ideas. |
