IWR6843ISK: Question about the position and velocity information of the dynamic objects in front of the robot?

Part Number: IWR6843ISK

I want to avoid dynamic objects so I need to know the position and velocity of the objects in front of the robot. Could you help me with the following questions:

1) Is it possible to get the velocity of the objects using the radar IWR6843ISK in ROS?

2) Is there any package that can measure the position and the velocity in real-time using the RADAR IWR6843ISK in ROS?

I'm in using '' roslaunch ti_mmwave_rospkg 6843_multi_3d_0.launch '' and read the topic information from "/ti_mmwave/radar_scan"

3) Could you tell me what means the velocity value in the ROS topic?

    Hi,

    First, I would like to point out that in order to truly differentiate between static and dynamic objects while the robot is moving, you would need odometry data in order to account for the velocity of the robot. This is not currently part of the ROS demo, and you would have to either add this yourself, or only do the static vs dynamic object classification when the robot is not moving. In reference to the velocity value that is pulled by the data handler piece of the ROS driver, this is the radial velocity of the point in relation to the radar, based on the points doppler signature. Let me know if there are further questions.

    Best Regards,
