Line-follower robot

A small car that reads a black line on the floor and keeps itself on it. The easiest robot to start with — no soldering at all, everything bolts together with the wires already made up. Tune the code properly and it will take the curves without wandering off.

Difficulty: Beginner
Build time: 2 hours and 30 minutes
Soldering: None needed
Estimated total: 935EGP
