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.

Mini Sumo Robot
Obstacle Avoider Robot This is a standart mini sumo robot model with two geared dc motors and three IR sensor. One IR sensor is on the front face, one is on the right and one is on the left face. It has also two CNY70 reflective sensors to detect the white path around the arena. It is controlled by PIC16F628A and it is use L293D as motor driver.

 

TERMIT 2 ( Mine Searching and Exploring Robot )
TERMIT 2, Mine searching and exploring robotTermit is a mine searching and exploring robot and is studied with solar energy. It was made in 2006. It's fully autonomous and remote control.The robot uses 6 dc motors to move the wheels, camera and robot arm. I use one PIC16F877A and PIC16F628A and two R/C devices. I use several mosfet for motor drives. To avoid obstacles I use five IR-sensors that give a picture of what the robot is approaching. From that information the robot decides if it should go to the left or the right. And if this robot detections a mine, it will transmit a signal to control center. The four wheels of termit have encoders. With those encoders Termit can save and transport the data of the path and also the coordinates of the founded points. The coordinate system of the Termit is an x-y system with a reference point that was taken from Termit's start point.

 

ROBO-MI05 ( Security and Cleaning Robot )
Robo-MI05 security and cleaning robotRobo-MI05 was made in 2005 for a competition organised by Middle East Technical University in Turkey and was awarded as the first. It is an indoor mobile robot. Robo-MI05 is completely autonomous and also can be remote controlled when it is wanted. Its mission is security and cleaning. It has an RC camera in order to transport the view to the computer. It has also two motion sensors to detect the obstacles or a movement. Its cleaning ability is provided with a vacuum broom which was made of a plastic cup. 

Robo-MI05 works in two ways. First, it autonomously works in a given environment by avoiding the obstacles without crushing them and sweeps. Second, man can watch its every movement with its mini RC camera and gives it commands by using a pc. Therefore, Robo-MI05 can be used as an exploring robot. When it has finished its cleaning mission, it is placed in a position at which it can see whole room. When it waits in that position Robo-MI05 is in stand-by position. Its RC camera is closed but its motion sensors are active. Whenever it motion sensors detects a movement it makes its RC camera became active and performs its security mission. It was programmed in C programming language.

 

FIRE-BOT
Fire-Bot robot project
Fire-Bot hobby robot

Fire-Bot is an autonomous mobile robot project, that can find the candles and blow them out. 
Fire-Bot is controlled by PIC16F877A. It has two DC motors and a servo motor. The DC motors are controlled with L293D integrated motor driver by using PWM of PIC16F877A. 

To detect the candles Fire-Bot uses its Sharp GP2Y0A21YK0F sensor and to determine whether or not it is close enough to the candle the robot has also a TSOP1738 IR sensor. At the beginning Fire-Bot measures the room's temperature with DS1821 temperature sensor placed on the fan and takes this temperature as the reference. When Fire-Bot catched the candle, it measures temperature and turns on the fan in order to blow the candle out. After the candles is blowed out, the fan is turned off.
