My first robot got made not due to a sense of creativity, but rather for securing good grades. SNAIL, my first robot was the first part of Group Design Project at King's College London and it got made in Nov-Dec 2007. It was a simple line follower which was made from LEGO Mindstorms RCX 1.0 & Robotics Invention System software.
SNAIL was not quiet the snail when it came to speed ! and could complete a square of 100 cm (25cm x 4) in 4-5 seconds.
