We did bad in the Independent university competition because we had some design flaw in our robot .So, we decided to improve our design and make it more light weight and compact. This time we used Arduino Nano instead of Arduino Mega which is based on ATMEGA328p based 8bit microcontroller. We use 18650 Li-ion battery. We also use ultrasonic sonar sensor to make sure the rover can pass through a tunnel without line.

We also improve our sensor. In this version we used famous sensor from Polulu. We are assuming this version will run perfectly in track.
