Line tracer robot:

Hi guys… today I took part in line tracer robot, a national level competition in which I won the 1st place. It is an autonomous robot which follows either black line in white area or white line in black area. It is completely controlled by micro controller. It consist of AT mega 16 controller, two 100 or 200 RPM motors for movement, photoelectric diodes are used as sensors to sense the black line, and a 12V battery is used for the power supply, when the robot is placed in an arena where a black line is drawn. The robot, with the help of the sensors follows the black line, the output of the sensor is given as an input to the micro controller which in turn rotates the wheel and moves the robot forward.

Auto mine robot-2010:

Hi Frnds, I participated in the national level auto mine robot competition, which drills from normal surface in an efficient manner and won the 1st place in it.

                                          

Working:

This auto mine robot is used for drilling. When this robot is placed in a pit, the flanges oscillate with the help of two 10RPM motors with 2kg torque (which are placed on either side of the flanges in the middle of the robot) and the digging mechanism which is at the top, touches the ground, rotates, collects the mud and discards it with the help of the tubes attached to it. For the movement of the whole robot 100 RPM motors is used. This is a manually controlled robot.This time I won the 1^st place as well.

My 1st step in Robotics…

This is my 1st year of college life; one of my friends asked me to partner him in a national level Robotics competition. I started to design a robot of my own for the given problem statement.
