After completing the first prototype, we noticed a few problems which we addressed in the following weeks. The first issue was the support wheels, which we replaced with a large ball caster at the rear center. Another issue was the large wheels. These were replaced with huge 3D-printed tires with silicone grips.
In the same week, we also finished wiring the main robot and screwed in the battery. After that, we uploaded the first code, and the robot was able to complete its first autonomous test drive.
