| Aaron Sowers (asowers2) Sameeth Gosike (gosike2) Rebecca Cole (rjcole2) Often, as a user of an R/C car is enjoying driving, the radio signal from the controller may fall out of range as the car drives away from the controller. When the R/C car falls out of range, the R/C car will no longer move and the controller must either walk in the direction of the car, assuming they know where it is, or must go find the car. Our proposed solution is to first alert the user that the car is going out of range by indicator lights at controller and possibly a buzzer or vibration mechanism on the controller since most users do not look at the controllers as they operate the RC vehicles. Additionally, we can implement an LED light or Buzzer on the vehicle to announce its rough location. In order to implement this, a bandpass filter circuit can be used to limit the frequency range and then have separate circuitry to determine the power being transmitted on that range. A MCU can be used to determine if the receiving signal power is over/under threshold and feed this data to the controller through a RF transmitter/receiver or Bluetooth communication. The data feed to the controller will instruct which lights need to be on at any given time. The final item that we can implement is instructions on how to bring the car within range when it is near the end of the available range. While a return vector and autonomous return function can be implemented, we believe this takes away from the user’s control of the vehicle and that it may be an undesirable function. Therefore, we will implement another LED/announcement system that can notify the user whether to go forward, left, right or reverse to bring the car back into a reasonable range. This will also help the user understand where the car is if they do not have visual contact with the car. |
