I made the plastic part 3 years ago as my first environment sensing robot (a bunch of ultrasonic sensors).
The saw-wheel only design was not good. So I extruded some circles to make the paddle wheels.
I also took out all the stuff on there (literally carried a bread board). So now I have a very basic setup, also very light (see the massive heavy battery it carried underneath).
This 2D car basically will be part of my newer/hopefully better navigation platform.
The WiFi buggy is another system connected to the navigation unit separately. The control is done by websocket.
The build is pretty simple electronically.
What's not visible is the 1 cell BMS which is in the red bundle on the right.
This is the build video (mostly electronics). At the very beginning you see the robot working and at the very end I show the basic web controller that steers it manually.
See the GitHub repo for info.
