2012-10-30 16:50:51 -0500 | asked a question | hector_quadrotor not responding cmd_vel message Hello, I am having the 1.6.16s ros-fuerte-simulator gazebo with Ubuntu 12.04 (64bit). I am having a similar problem as this post: link:Hector_Quadrotor Gazebo - Quadrotor x/y position does not update The difference is I can control the quadrotor in the two demos but not when I tried to control the robot with my own code. The one extra thing is my robot pose is not updated as well after I publish the msg. So basically right now when I publish a twist message to '/cmd_vel' and then I check the state with /gazebo/get_model_state', the linear and angular component under twist are all zero. Does anyone know why? Here's my code (without the part that I set my robot's pose): def __init__(self, proj, shared_data, velocityTopic='/cmd_vel'): Thank you for your help. |
