In this project our robot will sense wall according to sensor it will take action.
We design this vehicle for future automation. Assume that if any small robot is moving on the table then can it is possible robot can not fall from the table, when robot move to the end of table then robot sense the depth and at that time depth sense provide a signal to the microprocessor to stop the vehicle . It is also possible to reverse the robot on the table by using reversing the motor. When we reverse the motor then again we require a one more depth sensor on the back side of the robot.
For the depth sensing we use inra red rays . one photodiode and one infra red is connected in pair with the vehicle. We design the circuit so that when any car move on the track then both infra red sensor, front and back reflect the rays and circuit sense the track. If the track is okay then circuit sense the rays and move the motor forward. When the vehicle move forward then if the track is going to the depth region then infra red rays are not reflected from the surface and due to that processor get a signal and . vehicle move backward automatically.
