Line Follower Robot Circuit |
 This circuit consists of two parts : main board and the line sensing board.
The voltage regulation part, the circuit of PIC16F628A microcontroller, L293D motor driver are placed on the main board. The four leds on two sides of L293D motor driver is for observing the outputs to the motors.
Four CNY70 reflective optical sensors are used to detect the path with 74HC14 Schmitt trigger. The circuit can be programmed to detect the white path on black surface or vice versa. |

Obstacle Avoider Robot Circuit |
 Obstacle avoider robot circuit consists of three circuits. One of them is the main circuit which contains the microcontroller and motor driver parts. The other two circuits are obstacle sensors.
This obstacle avoider robot circuit is controlled with PIC16F628A microcontroller. The motors are driven by L293D motor driver. Voltage regulation circuit and a buzzer to give signal while detecting an obstacle.
The obstacle detecting sensors were prepared with
two TSOP1738 IR receiving modules and IR transmitting leds. |

Light Following Robot Circuit |
 Light following robot circuit consists of three circuits. One of them is the main circuit which contains the microcontroller and motor driver parts. The other two circuits are light detecting sensors.
The main circuit was controlled by a PIC16F628A microcontroller. The motors are driven by L293D motor driver. Voltage regulation circuit was prepared with a 7805 voltage regulator.
The light detecting sensors were prepared with
two LDRs (light dependent resistors). The sensitivity of the sensors can be set by using the trimpots on each sensor circuit. |

Mini Sumo Robot Circuit |
 Mini sumo robot circuit includes also control part, opponent detecting part and surface detecting part like sumo robot circuit.
It has three TSOP1738 IR receiving modules to detect the opponent and two CNY70 reflectvie optical sensors to detect the white path around the sumo robot arena.
The voltage regulation circuit, PIC16F628A microcontroller circuit and L293D motor driver circuit is placed on the control part. |
