Hi there. I am presenting you version 1.4.
The mayor change is that I’ve added third wheel to the back. I’m still experimenting with that but as you can see in the video observer can now drive over various obstacles without any problems. Also I moved Bluetooth module under the PCB to use the space that was there. Right now I’m drawing new PCB for observer, so that means next update will be version 2.0. I don’t want to spoil it, so I just say there’s going to be multiple sensors and when all will work out well I believe that version 2.0 will be awesome.
