@xiaoqiang when /cmd_vel = 0 BW-DR03 will short circuit, right?

@xiaoqiang BW-DR03 can break by electric break?

“Error: TF_NAN_INPUT: Ignoring transform for child_frame_id “base_footprint” from authority “/motor_driver””

how to solve?

above picture is true value of my car. I use Zltech hub motor 13 inch

Thank you!!

I have new problem when I publish cmd_vel 0.5m/s but /xqserial_server/Odom has 1.2m/s how to solve this?

Hi I’m Jaruwat form Thailand

I use BW-DR03 on Ubuntu ROS Melodic, pkg xqserial_server branches Lungu, connect with hub motor with True left wheel Ma1 H0 and right wheel Mb1 H1

I used Mtools for test BW-DR03 when I test on Open loop speed control mode positive PWM motor direction clockwise and PWM negative counterclockwise boths direction smooth

but when I connect BW-DR03 with ROS when I pub angular velocity robot direction is wrong such as positive angular velocity robot direction clockwise and negative angular velocity robot direction counterclockwise (no problem with linear velocity) how to solve this problem?

Thank you
