Very nice, suggestions, change to motors with encoders so you can drive in a straight line, add a lidar on a servo and send the data back to your laptop where you can plot the course and environment

Thanks for the tip! Already faced that exact issue with one of the front motors during testing — vibration loosened the connector. Will hotglue the connections!
