I am excited to share my experience at the recent 20230921 ROS Lawn Tractor Meeting. As a lawn tractor enthusiast, attending this gathering was a dream come true for me. In this blog post, I will provide you with a firsthand account of the event and highlight all the incredible things I learned and witnessed throughout the day. So, join me as I take you through the remarkable world of lawn tractors and the unforgettable moments from this fantastic meeting.


In this article, I will be discussing the recent ROS Lawn Tractor meeting that took place on September 21, 2023. The meeting was primarily focused on various topics related to the performance of the lawn tractor, including the effects of GPS update rate, steering speed, path planning, and the use of a simulator. Throughout the meeting, Jeff and Al, both experts in the field, shared their insights and concerns, leading to a fruitful discussion that aimed to improve the lawn tractor’s overall performance.

Effects of GPS Update Rate

During the meeting, Jeff delved into the importance of GPS update rate and its impact on the lawn tractor’s performance. According to him, a higher update rate allows for more accurate positioning and navigation. This ensures that the lawn tractor stays on the desired path, avoiding any potential obstacles in its way. However, Jeff expressed his confusion as to why the simulator worked better than the real vehicle when it came to maintaining accuracy.

Steering Speed and Path Planning

In addition to GPS update rate, Jeff also emphasized the significance of steering speed in the context of path planning. He explained how the lawn tractor’s ability to steer efficiently determines how well it follows a predetermined path. He suggested that improvements in the steering mechanism could potentially lead to more precise path planning and ultimately enhance the overall performance of the lawn tractor.

The Mystery of the Simulator’s Superiority

Jeff’s confusion regarding the simulator’s superior performance compared to the real vehicle sparked a captivating discussion during the meeting. Everyone contemplated the reasons behind this difference and brainstormed potential solutions. Jeff proposed some changes that could potentially bridging the gap between the simulator and the real-world performance of the lawn tractor.

Al’s Miro Board and Latest Video

During the meeting, Al shared his latest video, showcasing his Miro Board and its functionalities. He explained how the Miro Board helped facilitate collaboration and brainstorming among the team members. Additionally, he discussed a potential plan to upload the video on YouTube, enabling a wider audience to benefit from the insights and ideas shared during the meeting.

Help with Position Values on Plot Juggler

As the meeting progressed, Al sought assistance regarding the extraction of position values on Plot Juggler. He expressed his desire to create a coverage plot for testing, focusing on GPS rates and adaptive look-ahead in Pure Pursuit. Al’s request paved the way for a detailed discussion on data analysis tools and techniques, with the aim of generating valuable insights for the lawn tractor’s performance optimization.

Comments on Al’s Latest Video and Future Plans

Towards the end of the meeting, Jeff provided valuable comments and feedback on Al’s latest video, appreciating the efforts put into creating the content. He encouraged Al to upload the video to YouTube, as it contained valuable information for the ROS community as a whole.


The ROS Lawn Tractor meeting held on September 21, 2023, proved to be an engaging and enriching experience for all participants. Jeff and Al’s insights on the effects of GPS update rate, steering speed, path planning, and the utilization of a simulator opened up new perspectives on improving the lawn tractor’s performance. The discussion on Al’s Miro Board and his latest video not only highlighted the importance of collaboration but also showcased the potential of sharing knowledge with a wider audience. Moving forward, the ideas and suggestions shared during the meeting will undoubtedly contribute to the continuous enhancement of the ROS Lawn Tractor’s capabilities.
