In manual mode, the vehicle can be commanded through a wireless microphone to
1: turn left.
2: turn right.
4: about turn.
5: park left.
6: park right.
On getting the command of turn left, the vehicle turns towards left with 30 degree and after 3sec; it comes back to the original position. The degree in which the vehicle rotates, and the timing of coming back to the original position can be further adjusted based on our desired.
Right turn is same as that of left turn except for the fact that on getting command it turns towards right. All the modifications those are valid for the left turn is also true in this case.
Once the vehicle gets the command for “stop” it remains in the idle state. There after its control is hand over to the beginning state.
In about turn, the vehicle turns backward in two steps same as we did in our normal car. In first step the vehicle move only 90 degree and repeat the same in second step.
On getting the command to park left, the vehicle parks on the left side of the road in a single step.
Park right is same as that of park left, but here in this case, it parks towards the right side of the road.
You can also add two modes to the present design using two more switches. They are
In auto mode, the vehicle can be programmed to move at a particular place and park there. While moving, if any obstacle comes at the front of the vehicle, it will deviate its path automatically and come to the original path. The place where the vehicle is desired to move is the choice of the user; it can be either straight or bent path.
In our model, we have put three sensors at the front of the vehicle, so it is up to the user that, by what angle the vehicle should deviate. Further, it can be programmed on which side it should deviate, either left or right based on our desired. To alert the user that the vehicle is deviating an obstacle, a musical sound system is fitted in the vehicle, so that whenever it is deviating any obstacle, it will also play a music simultaneously.
It is the combination of both auto and manual mode. Here the vehicle can be commanded to move, to turn left or right. Further, while moving, if any obstacle comes on its path, it will deviate and come to its original path after deviating. However, if so happen that before coming to the original path, the sensor detects another obstacle; it will halt the movement of the vehicle, and play an alarm music as long as the obstacle is detected. The moment second obstacle is removed; the vehicle will continue its earlier execution.
