Proportional Line Following
From programs that rely entirely on proportional line following to those that use a PID-type program where "P" stands for the proportional line following component, proportional line following has proven to be a core mechanic in line following competitions.

Anty - LEGO Mindstorms Robot that behaves like an ant
Again a LEGO animal. This time it looks like an ant. It's interesting that this robot has no wheels and moves in a way very different from the rest of the "wheel robots".
There is much to be learned about mechanics from the way animals move. Ants are a good example. In the real world, an ant could carry a load of 20x its mass. It would be interesting to see how much load could this robot carry? Try it.

WRO Robot with a Ping Pong Balls Collecting Attachment - Full
This WRO robot is designed to collect a lot of ping pong balls in its container. It's built with LEGO Mindstorms EV3 45544 and 45560 sets. These are the LEGO Educational sets. The robot has two chains that collect the balls and push them into the container attachment. This is one of the larges robots we've uploaded at FLLCasts yet. You could learn a lot by following the building instructions and paying attention to the details of how this robot is built. All the alignment, all the connections. Really beautiful.

Varna - a sumo Robot from LEGO Mindstorms EV3
Nice idea. Lift the other robot and throw it in the air. Not easy, but Varna is trying to do it. It's a quite powerful robot with small wheels and gear ratio of x3. This means the power is increased 3 time from the motor to the wheel.
Surely you can work with it and even improve it.
