I want to make another larger robot

[ROBOTIS-Will]

Hi

My turtlebot3 waffle is working well and I appreciate the work you guys have done to make this happen.

Now I want to make another larger robot and I have a few questions for you. This robot will have large wheels say 6 inch and be able to drive all around my house without having problems with the carpet like the waffle does

Can you recommend a motor controller and motor that can take 6 inch wheels that have good encoders built in that can be used.

The laptop I use for the TurtleBot3 has ubuntu 16.04 loaded on it with ros kinetic The raspberry pi 3B+ is set up with ubuntu 16.04 and kinetic as well

Regarding the releases of ubuntu and ros as time has moved on and I am making a larger robot should I use later releases of ubuntu and ros or stay with the 16.04 and kinetic versions as I know they work?

Also do the versions on the remote laptop and raspberry pi 3B+ (SBC) of ubuntu and ros need to be the same or can they be different ? this would be like, I keep ubuntu 16.04 on the laptop and update the raspberry pi to sat 18.04 or 21.1. Or must they be the same on both

regards Max

Hi. again. :)

It seems like an error that occurs when running roslaunch turtlebot3_bringup turtlebot3_remote.launch on the PC.

Please refer to the link below turtlebot3_remote.launch https://github.com/ROBOTIS-GIT/turtlebot3/blob/ba10294ccb02891cd6af456bd4662e77813e3245/turtlebot3_bringup/launch/turtlebot3_remote.launch#L5 Have you ever run roslaunch turtlebot3_bringup turtlebot3_remote.launch?

If so, you are supposed to type TB3_MODEL. $ export TURTLEBOT3_MODEL=waffle_pi

Please Give it a try and let me know the result. Thank you.

You might be interested in TurtleBot3 Carrier below. https://emanual.robotis.com/docs/en/platform/turtlebot3/locomotion/#turtlebot3-friends-carrier

A custom wheel design is available in the 3D modeling so that you can use 3D print the part The ROS version on Remote PC and TurtleBot SBC should be the same as different distributions don't guarantee compatibility.

Thanks!

Hi I have a turtlebot3 and I am trying to get the slam in rviz and the raspberry pi image at the same time I do the following

Laptop run rescore Robot run roslaunch turtlebot3_bringup turtlebot3.rpicamera.launch laptop run roslaunch turtlebot3_slam turtlebot3_slam.launch

rviz opens I get an image from the camera but no lidar data

Can you help by providing the exact commands to also get the lidar data

Hi @Mdbirley

Robot run roslaunch turtlebot3_bringup turtlebot3.rpicamera.launch

The turtlebot3_rpicamera.launch only activates the Raspi Camera. In order to run the SLAM, you'll need to activate the LDS sensor and other necessary functions from TurtleBot3 with below command.

$ roslaunch turtlebot3_bringup turtlebot3_robot.launch

If you wish to run both camera and basic features, you can merge the content in the turtlebot3_rpicamera.launch into the turtlebot3_robot.launch as below.

<launch>
  <arg name="multi_robot_name" default=""/>
  <arg name="set_lidar_frame_id" default="base_scan"/>

  <include file="$(find turtlebot3_bringup)/launch/turtlebot3_core.launch">
    <arg name="multi_robot_name" value="$(arg multi_robot_name)"/>
  </include>
  <include file="$(find turtlebot3_bringup)/launch/turtlebot3_lidar.launch">
    <arg name="set_frame_id" value="$(arg set_lidar_frame_id)"/>
  </include>

  <node pkg="turtlebot3_bringup" type="turtlebot3_diagnostics" name="turtlebot3_diagnostics" output="screen"/>

  <node pkg="raspicam_node" type="raspicam_node" name="raspicam_node" output="screen">
    <param name="camera_info_url" value="package://turtlebot3_bringup/camera_info/turtlebot3_rpicamera.yaml"/>

Thank you.

Hi again

I copied the code that you posted below into turtlebot3_robot.launch as below. I then ran roslaunch turtlebot3_bringup turtlebot3_robot.launch

I then ran the slam launch file

I got the lidar data in rviz but not camera image

Do I need to compile the code if so can you assist with the actual compile commands and directories.

max

Thank you

[ROBOTIS-Will]

@Mdbirley Could you confirm the list of topics that TurtleBot3 publishes from your laptop?

$ rostopic list

[Mdbirley]

I copied your launch code in to the bringup launch file

Ran rescore on the laptop ssh into the tb3 and ran the bring up

opened another terminal on the tb3 and ran rostopic list and got the following

then ran rostopic on the laptop and got the same list

then ran slam on the laptop

then ran rostopic list and got this

sill not sign of the raspberry pi camera. It would be useful so I can steer the TB3 without needing to follow it

looking forward to the solution

then ran rostopic on the laptop and got the similar list

@Mdbirley Thank you for pasting the output messages. The camera image related topics are not being published. Do you get any error/warning messages on the terminal during the launch?

[Mdbirley]

I will test again in the morning from memory northing serious

Hi I have a turtlebot 3 and I have just made another ros robot to see for myself what is involved.

The turtlebot 3 I manage through my ubuntu laptop running 16.04 All is working well. I run the code roscore on the PC then bringup on the raspberry pi and then, to save raspberry pi processing power I run RVIZ on the laptop.

I have been controlling the second robot “Mybot-1” by vnc into the raspberry pi however as the apple computer does not have ros installed I have to run all the nodes on the raspberry pi. This includes heavy memory users like rviz

I tried to set up the ~/.bashrc file on the Mybot-1 to be the same as the turtlebot 3 but I still can not see all the nodes or see data

Can you please provide me with the setup instruction if I want to manage either of the 2 rovers from the same laptop. I do not need to run them at the same time. I just want to offload the Rviz onto the laptop so the raspberry pi does not get overwhelmed

I would prefer rescore to be run on the remote micro processor

I guess that this would be the same as if I want to run two turtlebots from the same laptop (at different times)

Many thanks Regards
