Hi. Today I am soldering from a DIY robot kit that drives along the line. The robot is not expensive and its work does not require complex components such as Arduino. It is enough to have a soldering iron, straight arms and some free time.
Such a robot is suitable for beginners, I would say the school project.
On the site of the seller a large selection of interesting DIY robots.
