'Follow me' car (A brief introduction)

  Recently, automatic technologies are increasingly being employed to make everyday tasks simpler and easier. Therefore, we decide to develop the automatic following technology. This technology has a very broad applications. For example, this technology can be used in an automatic following luggage. That means, the users do not need to pull their luggage because their suitcases will follow them automatically. In addition, this technology can also be used in some factories. O nce the automatic following technology is put to use, no more manpower will be wasted to transport weights. All the wagons can follow one person automatically. We plan to design an automatic following car as an example of the automatic following technology. The prototype of this product is shown in the picture below. Our automatic following car is consists of a car and a handle. The car can recognize the handle as a target and follow it.  Figure 1: The prototype of the automatical following c...

Week 4: We got it

Our work: 1. Refine the wire length in a proper visualization 2. Add some “feedback” functions to effectively control and monitor the car.  Method: Firstly, reduce the redundant wires such on the polarity. Next, to improve the integrated system, the feedback, as the significant part in a system, should be considered by adding monitor. The buzzer was chose as the output signal to inform customer that the car is out of limiting distance (50 cm) from their position. Two pins on the buzzer, one for ground and the other is for pin on Arduino, which could be activated by processor. Finally, the initial speed of car is too fast to easily test. Therefore, the PWM number was adjusted to 150 as the minimum number which could drive the motors. It is also have an interval to calculate the codes during the movement. What is more, the application of this model was re-discussed as the “auto-convey”, for example, it could be applied in factory, bank and supermarket. It will r...
