Re: How many beacons required

I need to be able to accurately position in 2D within a enclosed area of 2m x 8m. How many beacons are required for this? At the very minimum, you need 2 stationary beacons and 1 mobile beacon and 1 modem. Please, see for more details: https://marvelmind.com/download/ => https://marvelmind.com/pics...

Re: Can I create simultaneous paths?

I want to control 5 robots using Arduino in a large area but I don`t know if is possible to use the navigation system with more than one mobile beacon at the same time. If is possible, I want to know if there´s a limit of paths I can send at the same time to different robots. Yes, it is possible to...

Re: No data from hedgehog from in ROS after change to inverse mode

We are also having trouble with IA. Are the V4.9 Beacons truly a fixed ultrasonic frequency? Colleagues, Just to minimize the confusion with Inverse Architecture. You can't simply change the ultrasonic frequency for a transmitting beacon in the Dashboard, for example, HW v4.9, because it is defined...

Re: Movement of Stationary Beacons

Hello, There would not be a simple answer, because it depends on the size of the map and type of them - elongated, square, etc. - also, what kind of displacement - horizontal, vertical ... Our system is precise, but in normal conditions, thermal deformation would be just below our errors, so, we won...

Re: Getting multiple hedgehogs data at 100hz

What would be your recommandations (hardware / software) for recording multiple hedgehogs fusion data (3D positioning, simultaneously) at 100hz? I am thinking about storing the data to a SD card through SPI or UART board until the session is finished. Even better would be to transfer the data throu...

Re: Modem's config gets reset

Hello Maxim! I thought I posted the reply but apparently it didn't get uploaded. The weird thing is that when I plug in the "bad" modem to the other robot (5v dc-dc converter), it functions fine but the configuration gets reset whenever I plug it into the robot with the problem (also 5v d...

Re: Connecting HW4.9 Beacons to HW4.5 Modem

Hello, With high probability, there are two potential reasons: - Incorrect SW for a HW - Different radio profiles So, please: - Share the exact name of the SW you used for HW v4.5 beacons, modems and for HW v4.9 beacons - Share print screens of radio settings of beacons HW v4.9 and HW v4.5 and modem...

Re: Lidar in conjunction with beacons

Hello, I am working on an AGV localization and navigation project using the beacons and a RPLIDAR. I noticed the under the view tab of dashboard that there is a "lidars on robot" option. I've searched for more information on this but cannot find its implementation. Can you shed some light...
