My first robot.

Thanks for the suggestions CBenson. I already have an topic there robotshop.com/letsmakerobot … -lawnmower and I think you have also commented on it :slight_smile: But to be honest that forum board is [font=arial, sans-serif][highlight=#ffffff]causing difficulty or annoyance when try to add things there. Image upload does not work, When one try to edit one always need [/highlight][/font][font=arial, sans-serif][size=2]approval etc. So I think i stick to forum boards that works great and is straight forward, otherwise its to much time consuming :wink:[/size][/font]
[font=arial, sans-serif][/font]
[font=arial, sans-serif][size=2]I will review the other suggestion and maybe submit :slight_smile:[/size][/font]

[size=2][font=arial, sans-serif]Update:[/font][font=Helvetica, Arial, sans-serif]Testing the drive system. I need to remake the pulleys because they are slipping. Otherwise everything works fine![/font]

Feel free to replace the placeholder image on LMR with a photo of the last progress. When I had originally seen the post there, I was wondering what was going on until you added the CAD. The build log here shows it is much more than an idea / CAD drawing.
Note that even minor updates to the LMR push it back to the top of the list.

Cbenson, I have tried to edit on LMR and also tried upload pictures but upload want work and I always get marked as “spam”

Anyways, today I did the first test drive! Yey! One pulley still makes annoying sounds.

Congratulations! I can say I was certainly NOT expecting to see the Robomow RC306 on the lawn. Had you opted for a green shell for yours, it would really look commercial.

Thanks CBenson! I am running a RC312.

But is quite disappointed with the absence of smartness :slight_smile:

[size=2][font=Arial]Tonight I have begun building the robot’s URDF for better and nicer visualization in RVIZ when driving around. I also hooked up the 9DOF to test and confirm its functionally .I am using the (SparkFun 9DoF Razor IMU M0 - SEN-14001) and it was not easy to get it to work over ROS, but finally it did :wink:[/font][/size][size=2][font=Arial][/font][/size][size=2][font=Arial]The URDF will be an exact copy of the real robot and I will mostly use combined STL´S files as meshes for the URDF.[/font][/size][size=2][font=Arial]

[/font][/size][size=2][font=Arial][/font][/size][size=2][font=Arial]The robot will use two IMU´s, RTK, LiDAR, Wheel Odom, (also maybe VO if it works good outside) To get a good localization for the robot in the real world. I will also try to use robot localization package (sensor fusion) to combine several sensors data and get [highlight=#ffffff]state estimation. Lets see how it goes further down the line.[/highlight][/font][/size][size=2][font=Arial][/font][/size][size=2][font=Arial][highlight=#ffffff]My mission for this week is to mount 1xIMU, liDAR and try to run gmapping in the real world ([/highlight]previously shown as a simulation) and test virtual fences.[/font][/size][size=2][font=Arial][/font][/size][size=2][font=Arial]/RF[/font][/size]

The URDF is very time consuming but its coming along nicely. I have added all joints and are now working on to make them work as in reality.
The wheels are working great and the visualization in RVIZ presents the reality very well.

I have also started to work with the IMU joint and the ability to visualize the rotation of the robot (pitch, roll,yaw). To got this working I am using robot_localization pkg (sensor_fusion) Here I am fusing Odom and IMU to odometry/filtered. The visualization is still not very good for the IMU and will need some more love :slight_smile:

Long time since I posted here. :slight_smile: Jumping between different projects (which ones involves a new LiDAR for this robot) since the Sweep is working back and forth.

Anyways, I was also asked to design a concept for the ardumower project. So the last couple of days that´s have been main focus.

Here is the first concept picture of the Ardumower Arctic Hare




Looks like you are doing well on your first robot. Good job bro keep going and thanks for sharing your work with us.

Just an small status update:
Project is going a bit slower now since I am exploring possibilities of using AI on the robot. Training the robot to stay within the lawn, detect obstacles.

Here is a few small demos:

Jetson TX2 Deep Q learning in ROS Gazebo via camera. Goal is stay on lawn, avoid obstacles. We are getting there! (sorry for the bad video quality) :wink:

YOLOv3 on Jetson TX2 obstacles detection at 3.5FPS.

Looking good :slight_smile: I started working on my new project, it’s hard and hard for now. Good luck with yours

I see this project went dormant for a while. Is it already fully working?
