This robot is driven by ATmega 16 and uses advanced line following algorithm (written using Embedded C); it can trace straight line, obtuse turns, right turns, acute turns and can detect perpendicular junctions. It can also detect obstacles and stop at a safe distance. It also detects caves (using Proximity Sensor) and reduces its speed when inside one. The robot won 1st place in the competition held during Kaizen Robotics Program.
