2014-03-12 13:44:33 -0500 asked a question Controlling pr2 robot in ROS Hydro-Gazebo 1.9

Hi all,

So, I basically want to implement a path planning algorithm by simulating a scenario in "ROS-Gazebo" and I am using "ROS Hydro-Gazebo 1.9" distributions. My algorithm assumes that the robot is omni-directional i.e., it can move in both x and y coordinates, independently. As I have found out, "pr2" and "care-o-bot" are two robots that offer omni-directional motion. The only feature that I need from them is the omni-directional wheels and other features such as laser, arm, etc. are not needed. I would also need to get the odometry data.

Problem: I am not aware of any control plugin or library to control and move the "pr2" in "ROS Hydro-Gazebo 1.9". I am able to bring up the "pr2" in "Gazebo" using "roslaunch" command. But I cannot control it and move it around. To give an idea of what I want, in another case I am able to control a pioneer2dx using a differential drive controller plugin (libgazebo_ros_diff_drive.so). I wonder if such a thing exists for "pr2". If not, is there any other solutions to my problem?

I would greatly appreciate any helps towards finding a solution for my problem.

Thanks,

Ali

Hi all,

I am fairly new to ROS and Gazebo and I apologize if this question seems easy in advance.

2012-12-12 12:01:16 -0500 asked a question Sick lms 200 interface

Hello!

I am very new to robotics society, so I apologize for this silly question. I have a sick lms 200 (laser rangefinder) which is not connected to robot yet. I have just connected it to computer and I am able to get data from it by use of drivers produced by sick company. But, I need to interface with it through c++ or MATLAB. Also my system is windows and not LINUX. I do not have that much knowledge of computer science. The ROS developed code is for linux and The ARIA developed codes for interfacing with sick, seems to be written for a robot mounted sick. Therefore, I am not able to use them, because there is no robot installed yet. I will truly appreciate if anyone could help me on this problem. I am confused and I do not know what to do.

Your friend, Ali
