termit mine searching and exploring robot

explorer robot Termit 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 robotRobo-MI05 security and cleaning robot

Robo-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.

scorer ball playing robotScorer ball playing robot

Scorer is a ball playing robot. It has three geared dc motors. Two for the wheels and one for its robot hand. At the begining ęt searchs for the ball. It has two IR sensors for finding the ball when it detects the ball it moves to catch it and hold it by using robot hand. After it hold the ball it starts to search for the castle. The Scorer has two other IR sensors to find the castle and the castle also has an IR emitting circuit. Therefore when the Scorer find the castle it goes through the castle to make score and goalll!:) Scorer provides the contact by its LCD. It gives messages of all the steps that it follows. The main circuit of Scorer is controlled by PIC16F877A and the castle has also an IR emitting circuit that was prepared with a PIC16F628A.

terminator

terminator mini sumo

Terminator is a mini sumo robot with four mini dc motors. Its motors are powerfull Faulhaber motors and its wheels provide a good friction in order to be not pushed out of the arena. It has five IR sensors to detect its competitor. Two of them are on the front face, two of them are on the right and left faces and one is on the back. It is controlled by PIC16F628A microcontroller. There are two CNY70 sensors under the robot body to detect the white path around the arena. Terminator is the champion of the International Robotic Days in 2009 organised by Middle East Technical University.

symirna line follower

symirna line follower robot

Symirna is a fast line follower robot. It has two geared dc motors which are only 200 rpm. Despite of this low rpm of its motors, its design makes it fast. It has four CNY70 reflective optosensors to detect the white path on black surface. It is controlled by PIC16F628A. Its motor driver circuit was prepared with L293D. Symirna is the winner of the Line Following Robot Category of Robot Competition in 2008 organised by Istanbul Technical University and the third of the National Robot Competition in 2008 organised by Aegean Region Chamber of Industry.

obstacle avoider and 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.

Line Follower Robot Without MCU

This is a simple line follower robot that is designed for the purpose of applying pwm control with opamps without using any microprocessor. 5 CNY70 reflective optical sensors and 5 NE555 opamps are used. To drive the motors I've used two mosfets (IRFZ44). This line follower robot is very effective, it has a smooth motion on the path.
