After debugging it further, I think this's due to a bug in ament_cmake where it does prefer the system installed package

That's very unfortunate, I would recommend you looking at run_move_group to see how to launch the move group node + RViz

2021-07-01 07:44:12 -0600 answered a question ROS2 rviz node -> two robots with different namespaces

It's not possible with MoveIt2 because we can't specify the namespace of the move group node when creating a move group

Hi all,

I'm getting this error

machine.env_loader must have been assigned before creating ssh child instance
The traceback for the exception was written to the log file

when running any .launch file on my local machine( I'm not using ssh at all)

I'm using ubuntu 16.04 + ROS kinetic

I have to admit that I missed up with /etc/hosts and ROS_MASTER_URI but I don't know what I did wrong :)

2018-02-28 20:26:57 -0600 marked best answer arduino rosserial with interrupt

Hi all,

I'm now building a robot which uses interrupt to count up the number of ticks and do the calculations in arduino nano, after that I decided to use rosserial library to send the number of ticks to the raspberry pi, when I put the code which send the number of ticks inside the void loop function it works, but if I but the code inside the interrupt handler I doesn't work very well and when it work it send strange numbers for example "6074229997415956480" number of ticks .

ISR(TIMER1_COMPA_vect){

    RTicks_msg.data = EncoderR.GetTicks();
    LTicks_msg.data = EncoderL.GetTicks();
    RTicksPup.publish(&RTicks_msg);
    LTicksPup.publish(&LTicks_msg);
    nh.spinOnce();
}

any help ..?

thanks,
