2019-02-19 14:10:05 -0500	marked best answer	Dynamixel X with OpenCM 9.04C and ROS possible or OpenCR/U2D2 need? Dear all, I plan to build a robot arm with Dynamixel X servos. I also want to use ROS tools and drivers for the servos. I found there is a cheap OpenCM 9.04C Controller board (~20USD) available, also the U2D2 USB Interface (~50USD) and then the OpenCR Board (~200USD). In the ROS packages I only found the OpenCR mentioned. My plan is that ROS runs on the PC and I just need the interface from there to Dynamixel X. My question is: Can I control the Dynamixel X (T version with 3 cables) on ROS through the OpenCM 9.04 board? And can you name me the ROS packages I need for this? Or do I need to buy one of the 2 other boards (U2D2 or OpenCR)? Thank you for any help, I'm new to Dynamixel ;-)

2019-02-08 12:23:56 -0500	marked best answer	Advantages of Dynamixel X -T / -R TTL vs RS-485 I'm planning to buy servos for a humanoid robot that I control with ROS, is there any disadvantage of the TTL vs RS-485 versions? EMC/Electric disturbance / how many servos on one line/bus are possible... or others?

2016-08-22 22:51:46 -0500	commented answer	Autostart ROS Topic was closed by the admin, however it might be helpful for people still searching for this how I solved it on Raspbian: Just copied the scripts that need to be sourced (see above) directly into the /etc/rc.local.

2016-08-15 20:51:59 -0500	asked a question	ROS Kinetic on Ubuntu Mate 16.04 ARMHF (Raspberry Pi 3) I'm trying to install ROS Kinetic on Ubuntu Mate 16.04 following these instructions: http://wiki.ros.org/kinetic/Installat... The site says that armhf is supportet. However when executing `sudo apt-get install ros-kinetic-desktop-full` I always get the error `unable to locate package ros-kinetic-desktop-full` Same for desktop or basic install. Is there any idea what I could do? `ros-latest.list` contains as first line `deb http://packages.ros.org/ros/ubuntu xenial main`, that should be ok...

2014-10-24 10:48:07 -0500	marked best answer	Indigo on Raspberry/Debian - dependency problem / catkin error Hello together, I try to get Indigo work on the raasberry pi (raspbian) and get the same probems as mentioned here: http://answers.ros.org/question/19225... As there is no solution yet, I post some more details, maybe someone can help: I'm following the steps from the tutorial here: http://wiki.ros.org/indigo/Installati... . With the following command, I get the dependency problem: pi@raspberrypi ~/ros_catkin_ws $ rosdep install --from-paths src --ignore-src --rosdistro indigo -y --os=debian:wheezy ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: roslisp: No definition of [libconsole-bridge-dev] for OS [debian] collada_parser: No definition of [liburdfdom-headers-dev] for OS [debian] rosconsole_bridge: No definition of [libconsole-bridge-dev] for OS [debian] class_loader: No definition of [libconsole-bridge-dev] for OS [debian] urdf: No definition of [liburdfdom-headers-dev] for OS [debian] collada_urdf: No definition of [liburdfdom-headers-dev] for OS [debian] urdf_parser_plugin: No definition of [liburdfdom-headers-dev] for OS [debian] cpp_common: No definition of [libconsole-bridge-dev] for OS [debian] geometric_shapes: No definition of [libconsole-bridge-dev] for OS [debian] rosbag_storage: No definition of [libconsole-bridge-dev] for OS [debian] tf2: No definition of [libconsole-bridge-dev] for OS [debian] Is there a way to get this solved? I also tryed to install the packages with apt-get, but could not find a source that provides the packages for raspberry pi. And I found that manual installation of the armhf packages from sides like https://packages.debian.org/search?ke... does not work, as the dependencies go on and on forever... Then I red that I could just skip the step above, so I went on to the next step and get the error as follows. Is this error maybe due to some other root cause, and can someone help to solve this?

2014-10-24 08:07:15 -0500	marked best answer	Using ROS for Biped motion planning I bought a 60cm humanoid robot with RC-Servos. I'm already able to drive all servos with ROS. Are there ROS packages for BIPED motion planning available? Also the question arose, if URBI might have advanatages compared to ROS for a biped?
