BW-DR03 with ROS wrong direction control
-
@jarubank edit xqserial.launch file, change those two parameters “wheel_radius” and “max_speed” to the true value of your car.
-
above picture is true value of my car. I use Zltech hub motor 13 inch
-
@jarubank maxspeed = 2 * 1.224/0.5 = 4.896, so maybe 5 is the true value of maxspeed.
-
@xiaoqiang maxspeed = 300rpm = 5 rps
-
“Error: TF_NAN_INPUT: Ignoring transform for child_frame_id “base_footprint” from authority “/motor_driver””
how to solve?
-
@jarubank the nan is a wrong data. I have updated the code, added a nan value filter . Use git pull, get the new code, then catkin_make .

-
@xiaoqiang BW-DR03 can break by electric break?
-
@jarubank no, the motor is braked by short circuit in BW-DR03
-
@xiaoqiang when /cmd_vel = 0 BW-DR03 will short circuit, right?
-
@jarubank right
