Re: Connection problem via UART

Hello,

This code looks like some modification of our ROS node.
It takes serial port name from ROS parameters instead command line parameters as in our node.
May be something occurs with serial port name when it passes through ROS parameters API.

Re: IMU Quaternion 2 values are always 0

Hello,

What version of software do you use?
As I remember, we have fixed this issue in last software update (V6.210).
If you have updated the software and the issue is not fixed for you, please clarify what kind of system (IA or NIA) and what types of beacons do you use?

Re: Data of device A is not collected when B is occluded (same to B and C, C and D, etc)

Hello, Yes, this is known issue, we have also found it recently - in NIA on higher update rates, when one of the mobile beacons can't be tracked, it also locks tracking of one another mobile beacon. We will fix this issue in next software update. Current workaround is to reduce update rate to 4 Hz o...

Re: Connection problem via UART

Hello, 1. If you connect via real UART on the mobile beacon, do you use any UART to USB converter for connection to PC? 2. If you use virtual UART over USB (direct USB connection of hedge to PC), try execute reset of the hedge after connection. It can be done by hardware reset button on the beacon o...

Re: Having problem to setup the marvelmind's "Starter Set NIA-SmallDrone"

Hello, Have you followed the manual in part of getting access to the serial port (adding user to dialout group)? By default Linux can lock access to the serial port for users.  If you connect a beacon instead of the modem via USB, do you see it in the dashboard? Try type 'ls /dev/ttyACM*' in the ter...

Re: About the submap

Hello,

We have measured all required distances between submaps manually when tested V100 robot.
Also we have used floorplan picture uploaded to dashboard to check correct location of the beacons.

Re: Big Map with Drone

Hello, 1. Yes, you can use mini-Rx as stationary beacons. But in this case you will need to specify positions of stationary beacons or distances between them manually, because mini-Rx doesn't have ultrasonic emitter, so map can't be build auomatically. 2. You can use HW4.9 or Super-Beacon as mobile ...

Re: Big Map with Drone

Hello, If it is possible, you can place stationary beacons as a grid with 20 meters size, as shown on atached picture. To cover 100x100 meters area you will need 36 beacons and 25 submaps. Each submap will have 4 beacons on will overlab 2,3 or 4 close submaps. Service zones should overlap by 1...2 m...

Re: Ultrasound precision small room

Hello, On the screenshot I see you have 'Number of periods' 1 for the mobile beacon. This may be too weak ultrasonic emission even for so small distances. Please try 5 or 50 periods. If this will not help, please share file generated by 'Save map' button and screenshots of the embedded oscilloscope....

Re: About the submap

Hello, It seems M1/M2 function have some issues. We will check and fix it in next software update. Thank you for the feedback. This function helps to move submaps correctly relative to each other. You don't need it if you know real relative locations of submaps, or if submaps have common beacons. In...
