Lego Mindstorms NXT - Auto Parking Car, Self-Parking Car

This car can search for a parking spot (using ultrasonic sensor), and when it finds an empty space, it starts measuring it, and if it was enough, it parks itself automatically. If the space is narrower, it parks itself in another way, like SMART car. If the space is too small to park, it keeps on searching for a parking spot.
The car can also move itself out of the parking spot when it receives a voice command.

Lego Mindstorms NXT - The car that watches out for its head

This small robot starts with raising its head a little up and keeping it raised because gravity pulls it down. It goes direct until it approaches any thing then it decelerates its speed (so that if it hits that thing, the hit is not hard). Then when it is 25cm far from that thing, it raises its head and turns back randomly either to the right or to the left. The randomness was important to get out from small spaces after many tries.
