I am not able to move the robot because of the following issue:

Hi, Did you get any error in the upper terminal? You are probably missing twist_mux. Please check with sudo apt install ros-noetic-twist-mux

Hello, unfortunately it is not solved. I do not think the problem is about the twist_mux

Upper Terminal:

[ERROR] [1688669003.309345017]: Couldn't open joystick /dev/input/js0. Will retry every second.

Hello Erencan To me it looks like the twist teleop keyboard is not running in the right namespace. Please use the keyboard_teleop:=true parameter in the smb.launch launch file. That should already start the keyboard teleop in the same terminal.

Hello,

I have already tried it before. It didn’t work.

I forgot to put the correct cmdvel topic name. Here is the solution:

$ rostopic list | grep cmd # /control/opc/cmd_vel $ rosrun teleop_twist_keyboard teleop_twist_keyboard.py /cmd_vel:=/control/opc/cmd_vel
