How to install ROS on Poineer-3DX
Hi,everyone. I have a Poineer-3DX robot, the onboard computer system now is Windows 2000. I can connect the robot with my laptop(already installed with ROS hydro and Ubuntu 12.04) through a serial line。 My first question is: whether I should install ROS on the onboard computer? If I have to, how to install? The instruction of the installation is not clear.
My second question is :When I send the command
rostopic pub -1 /RosAria/cmd_vel geometry_msgs/Twist '{linear: {x: 0.1, y: 0.0, z: 0.0}, angular: {x: 0.0, y: 0.0, z: 0.0}}'
to the real robot, it can move, but very slowly even I change the linear x velocity to a bigger value, what's the problem? However, if I run the command to the simulator, the change of the velocity works.
Thank you guys.
This is just a guess (from working with p2os), but the robot may move slowly because somewhere in the params the max velocity value is set to a very small number. Sometimes, with ROS nodes, parameters are not documented well. See if you can find it in the source or if there is one set by the sim.
