Week 3: We are almost there

Our work: 1.      Upgrade the construction by removing a slaver Arduino on the car 2.      The car initially could recognize the signal source and have some response movements. Method: The original hypothesis is to modulate each function as a component model. The alternative way is to synthesize the total car by using only one processor, which means impose one master processer instead of attachment slaver. Thus, there are only one master and one slaver communicating with wireless modulation which called as 315 mhz remote control. After connecting each wire, the predictable result is that when one distance of slaver ultrasonic is near to that of master, the wheels will rotate. These testing programs only ensure the conception was correct. The most complex part is to constrain the condition codes to make the response sense. In details, three slaver distances on the car compare to the distance on the controller, which difference is...

Week 5: Final Adjustment

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.
