The goal of this project is to be able to print it in a 20x20x20 3D printer. of course, this would also cause design difficulties, but also many parts that would need fit be fitted together. This project will ...

Re: Project robot lawnmower

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 vi...
