I am an intern at AMMACHI Labs, Amrita University, Kollam, India and currently working with ErleCopters that we just purchased.
I have been following the simulation tutorial on http://docs.erlerobotics.com/simulation/vehicles/erle_copter/tutorial_1 . When I run ../Tools/autotest/sim_vehicle.sh -j 4 -f Gazebo in the terminal window, the following error shows up:
" Unknown command 'map overlay /home/optimus/simulation/drone_ws/src/ardupilot_sitl_gazebo_plugin/ardupilot_sitl_gazebo_plugin/worlds/almost_empty_world/map_w40m_h40m.png -35.363261 149.165230' "
Also, when I type, " roslaunch ardupilot_sitl_gazebo_plugin erlecopter_spawn.launch " in another terminal window, the XTerm window shows:
" Fatal: Failed to send on control socket: Connection Refused "
How can I solved this problem?
Thanks a ton!
