The most important thing is that the size of the robot and the chess board are appropriately chosen.ДЄfter the design of the robot is completed and built, a control system is needed to move the robot to the correct position. There are many robotics arm that you can purchase from RobotShop or Trossen Robotics. I is not nessesary to design the arm by your self. What is needed is to add a couple of resistors on each sensor, that will make sure that the output of the sensor is either 1 (high) or 0 (low). Without setting these standards, the sensors states will be вЂњfloatвЂќ when they are open, and NOT zero. A circuit that accomplishes this task is needed. In order for the microcontroller to determine whether the sensor is open or closed, the output of each sensor must be either 1 (high) or 0 (low). Before connecting them to the microcontroller, some standards are set. As it described before, each sensor will cause either an open or closed circuit. Next, the circuit that will handle the 64 sensors is designed.

By moving the checkers around the sensors will be opened and closed accordingly. Now, each checker has a small magnet beneath it that will affect the sensors. When a magnet approaches, the two leads will touch each other (attracted) which will cause a вЂњclosed circuitвЂќ, otherwise it is an вЂњopen circuitвЂќ. Inside the switch there are two pieces of metal. Operation of reed sensor is shown in fig (5). Whenever a magnetic field is sensed, the switch will turn on, otherwise it will be off.

These switches are sensitive to magnetic fields. Under each square, there is a magnetic sensor called вЂњReed SwitchвЂќ. For an appropriate size, the board size is set to be 40 by 40 Cm, with 2 by 2 Cm for each square. The first thing to design is the chess board.
