Line Follower Robot Without Microcontroller
Line follower robot without microcontrollerThis is a simple line follower robot that is designed for the purpose of applying pwm control with opamps without using any microprocessor. It follows the white path on a black surface.

The robot has five CNY70 reflective optical sensors and five NE555 opamps. Two mosfets (IRFZ44) was used to drive the motors. There is also a 74HC14 Schmitt Triger on the circuit board to transmit the signals from CNY70 sensors to the opamps

Although the robot has no microcontrollers, it is still very effective and has a smooth motion on the path.

CYCLOPS ( Obstacle Avoider Robot )
Obstacle Avoider Robot Cyclops Cyclops is a obstacle avoider robot with one obstacle detector. This obstacle detector is prepared with an IR led and IR receiving module. To detect the obstacle all around the robot the obstacle detector was mounted on a stepper motor. The stepper motor comb the surroundig of robot by turning clockwise and counterclockwise.

Sumo Robot
Sumo Robot ProjectStandart sumo robot model has four TSOP1738 IR sensors to detect its opponent and two CNY70 reflective optosensors to detect the white path around the arena. As the actuators two powerfull geared DC motors were used and these motors were controlled with L298 integrated motor driver circuit. The sumo robot is controlled by PIC16F628A microcontroller. The voltage is supplied by a 12 V accumulator.

Obstacle Avoider Line Follower Robot
Obstacle Avoider Line Follower RobotThis is a standart line following and obstacle avoiding robot model. As a line follower it follows the white path on black surface. When it detects an obstacle on the way it stops a short time and changs its way to not crush the obstacle. Therefore, it keeps moving and finds its own way. It has three CNY70 reflective optosensors to detect the white path on black surface and an IR sensor to detect the obstacles  while it follows the path. The IR sensor circuit was prepared by using TSOP1738 IR Receiver. It is controlled by PIC16F628A microcontroller that was programmed with C. Its two dc motors are driven by L293D.

HUNTER ( Mini Sumo Robot)
Mini Sumo Robot HunterHunter is a four wheeled mini sumo robot with geared dc motors. The geared DC motors are 6 V 600 rpm. To control the high speed of these motors and not to get out of the sumo robot arena, it has a specific programme. It detects its opponent by its TSOP1738 IR sensors. There are 4 IR sennsors; two of them are on the front face and the other two are on the each sides. To detect the white path around the arena, it uses two QRD1114 reflective optosensors. It is controlled by PIC16F877A and the DC motors are controlled with L293D integrated motor driver circuit.
