IWR6843ISK: Safety Bubble Lab

Part Number: IWR6843ISK

I am trying to test the IWR6843ISK. In the Resource Explorer for mmWave sensor, there is this Lab demo "Safety Bubble with ROS for mmWave". This is a bit similar to our use case, but we will not use a robot.

We just want to set a safety bubble, and then an alarm will sound if an object is within that safety bubble.

Is there a way to use this lab demo just to detect if an object is inside the safety bubble?

    Hello,

    Would you be using ROS? Is the sensor on a moving platform?

    If no to both above, then I would suggest using the area scanner demo: https://dev.ti.com/tirex/explore/node?node=APGSzBLXJLTE5H6k58VhkA__VLyFKFf__LATEST

    Hi. I will not be using ROS. The sensor is on a moving platform, thus I can't use the area scanner demo.

    Hi Zyra,

    Since you are not using ROS, I assume you need something custom. Our robotics demos will not help directly, but they will provide a solid reference. The robotics demos are built on top of the radar's Out of Box Demo. I would first build the hardware and software that allows for grabbing point cloud data from the mmWave sensors. What is your host processor, presumably the same processor that controls the robot? You would need to use a peripheral to connect to the mmWave sensor and build a parser for it.

    The Safety bubble demo uses a occupancy grid for the object detection. If you are not using ROS, you would probably have to develop something similar on your processor. Alternatively, I would still suggest the area scanner demo here. Although it seems like it is for a stationary case, you could repurpose the area scanner demo for a moving case. You could ignore the static point outputs.
