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