Week 5: Final Adjustment

图片
Our work: 1.      Strengthen the restricted condition to enhance the error-tolerant rate of unpredictable situation. 2.      Reinforce the signal transmission by adding antenna on wireless communication module. Methods: For restraining the condition, reduce the setting distance number. In one judgment code, not only program one ultrasonic, but also range others. In that case, more completive condition could touch the rational level. In addition, two antennas were added to the pair of wireless communication module, which were used to extend the detecting ability.  Results: Figure 1: The final model of the automatic following car with antennas Problems: We want to attain a smooth movement. However, depends on the limitation of the hardware, such the calculating ability of processor, the heat will affect the capability and the affecting noise. Even the time delay is fluctuating.

'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...
