I want to share my robot with you. it was made in 2006.Its name is
TERMIT The TERMIT is a mine searching and exploratory robot and is
studied with solar energy.It's fully autonomous and remote
control.The robot uses 6 dc motors to move the wheels, camera and
robot arm. I use one pic16f877 and pic16f628 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.I will wait your comments.

mine-detection?
Flashy!
Navigation by IR? I’d love to see the details of that. I’m fostering a new-found hate for navigation by IR - but of course, I’m only using the 50c IR LEDs from the shop…
What is the mine-detection algorithm?
mine / metal detection
Hello
Mine detection was the purpose of my project in university. It was only a prototype, I couldn’t found enough budget to improve it. There is no metal foil around it. The thing that looks like metal foil is actually a plastic material. The robot works in the idea that the mines are placed on smooth surfaces. Therefore on the rough surfaces the robot arm that carries the metal detector is protected in a division under the robot’s body. The metal detector is inactive until the robot reaches a smooth surface. And when Termit reaches a smooth surface it automatically starts detection by getting out its robot arm carrying the detector. In this way the detector will be away enough to not detect the robot itself.
Actually this version of Termit was the second version of it. Firstly I built an explorer robot without metal detector. While I was designing it in 2005 I tried to perform mechanical design as good as it can move on rough surfaces with very little budget. At the link that I give you above there is a video of that first version of Termit ( without metal detector ). You can watch it in action on rough surface. I will prepare another video of the second version soon for you.

Gps and mapping system
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. I couldn’t have the opportunity of using GPS system so I have tired to perform a basic mapping system with little deviations which can be caused by the encoders.
The suspension system is very special for me because I did it by myself. Every parts of Termit was handmade. And also thank you for your comments
