I think the wiring diagram shows pins 2, 3, 5, & 6 being used for the encoder inputs but the arduino code uses 2, 3, 4, & 5. Made my robot go in circles on rviz.

Hello!

A wonderful job! Can you help me a little bit with the speed_to_pwm ration. How did you obtain it?

All the best!

WHen connecting to rplidar and running the launch file, one error keeps on coming i.e., LOST SYN TO DEVICE, RESTARTING

Hello
Your arduino firmware there is lots of different variable and some constant values. Some of them don't have any comment. Can you write comment for these lines ?

//990 and 1000 ?
speed_act_left=((pos_left/990)*2*PI)*(1000/LOOPTIME)*radius;           

//0.882 and 0.00235 ?
PWM_leftMotor = constrain(((speed_req_left+sgn(speed_req_left)*0.0882)/0.00235) + (speed_cmd_left/0.00235), -255, 255); 

Hi, i am doing an project like you project but i have used RPlidar A1 instead KINECT. So i want to ask you how to create launch file to use with RPlidar A1( i use motor with encoder and arduino + pi3 like you). Pls help me! Thanks you very much!

Hi Robin,

I am working on a similar project. I am also using Arduino to give the motor commands. Do you think I should add IMU to the RasPi directly (using GPIO pins) or I should add it to Arduino, which is already controlling the motor?

Hi,
forgive my english .. it's really bad ..
I have a problem with your project.
when i launch roslaunch nox nox_bringup.launch on Rpi
everything is ok except this:
[joint_state_publisher-1] process has died [pid 3887, exit code -6, cmd /home/ubuntu/catkin_ws/src/joint_state_publisher/joint_state_publisher/scripts/joint_state_publisher __name:=joint_state_publisher __log:=/home/ubuntu/.ros/log/b7e3dfe8-7d05-11ea-9aa0-080027e45c80/joint_state_publisher-1.log].
log file: /home/ubuntu/.ros/log/b7e3dfe8-7d05-11ea-9aa0-080027e45c80/joint_state_publisher-1*.log
since odometry doesn't work, could this be the problem?
