IWR1843: Sense and Avoid Demo vs ROS Driver

Shine

Part Number: IWR1843

Hello Champs,

https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1067313/iwr1843boost-3d-pointcloud-detection-in-ros?tisearch=e2e-sitesearch

In the above post, it mentioned that the the visualization node of Sense and Avoid Demo is different from ROS driver. Customer wanted to know what's difference between the ti_mmwave_sensor start from Sense and the ti_mmwave_sensor start from Sense and Avoid Demo and ROS Driver, is there any difference between their point cloud quality?

Besides, he followed the steps in https://dev.ti.com/tirex/explore/node?node=A__AM9Z52z2Z8D6CF33aY6XjQ__com.ti.mmwave_industrial_toolbox__VLyFKFf__4.10.0 to start the ti_mmwave_sensor from ROS Driver. He wanted to know how to start the ti_mmwave_sensor from Sense and Avoid Demo?

Thanks

Hello Shine,

Can you clarify what two sensor starts the customer is comparing? Sense and Avoid + ROS Driver versus ROS Driver? There is a difference in visualization between Sense and Avoid and the other demos since they use different "RVIZ" files, but the configuration sent to the device is the same. What this means is the point cloud behavior is the same between the two, but what from the point cloud is kept and how that information is manipulated is different.

Note that the "Autonomous Robotics with ROS for mmWave" demo is indeed the Sense and Avoid demo, only difference is naming.
