Based on the tutorial 2: Obstacle Avoidance of Erle Rover,
After starting MAVProxy and gazebo, in the 3rd terminal once I run the following command line:
rosrun erle_rover_explorer erle_rover_explorer.py
The rover should start moving. However, the Rover doesn't. It stays still in the same position.
However, if I try to command the rover using MAVproxy, i.e. rc 3 1900, it can move.
What could be the reason? Please advice.
