2016-06-04 13:02:36 -0500 | asked a question | Modeling a heavy tricycle robot I am modeling (ros kinetic + gazebo7) heavy (more than 700 kg.) tricycle robot. To control its movements in Gazebo simulator I am using gazebo_ros_tricycle_drive plugin. All seems to work more or less when I control model using teleop_twist_keyboard.py utility, but when using standard navigation stack and specifying targets on a map my model is not stopping near given target, but continues to roll as if by inertia. Should I tweak some (which ones?) parameters in aforementioned tricycle plugin or in URDF model of the robot? Or should I instead use |

2016-06-03 04:42:44 -0500 | asked a question | Use different LaserScan source for obstacle avoidance Is it possible to use different LaserScan source for obstacle avoidance? In my robot model I have several laser scanners installed and want to use one for navigation and the other one (possible more than one) for obstacle avoidance. I am using ROS Indigo and Kinetic with standard navigation stack. |
