We have been optimizing our robot car a lot recently. There are a few new changes:

(1) A new 5 way line follower has been added to replace the original ones because they are too big for such a competition.

(2) The layout has been siginificantly re-adjusted – not sure if we made good choices lol

(3) Some other sensors have been added.

(4) We are having some challenges in recognizing color sticks. Still trying to adjust the hardware and codings.

Time is limited for all these works!
