cmd_vel_smoother
Interpolate velocity command to be published periodically with acceleration / deceleration limit.
What is this?
Basically this node interpolates velocity not to violate acceleration limit by decelating from last received velocity.
For example PR2 has 10Hz control loop in base_controller and if no cmd_vel has come within 0.1 seconds, the controller stops all the moving motors for safety.
If move_base node publishes cmd_vel lower than 10Hz (let it be 5Hz) but continues publishing, controllers send signal to motors forward for 500ms and stop for 500ms, which causes "rattle" (= moves and suddenly stops repeatedly) and can damages motors and other hardwares.
Parameters
-
~x_acc_lim(Double, default:0.1)
limit value of x-axis translational acceleration. This node publishes velocity not to violate this value.
-
~y_acc_lim(Double, default:0.1)
limit value of y-axis translational acceleration. This node publishes velocity not to violate this value.
-
~yaw_acc_lim(Double, default:0.1)
limit value of z-axis rotational acceleration. This node publishes velocity not to violate this value.
-
~desired_rate(Double, default:10.0)
This node interpolates velocity commands to keep the rate
-
~interpolate_max_frame(Int, default:5)
Max message count to be published from last received velocity command.
Discussion
- This package is originated from the discussion in https://github.com/ros-planning/navigation/issues/405 .
I have not looked into detail of implementation but it seems that similar nodes for turtlebot robots exist: https://github.com/yujinrobot/yujin_ocs/tree/devel/yocs_velocity_smoother .
